As you know, environment, nutrition and stress are the main factors that affect human health. Everything that enters our body from the outside helps or harms us.

They destroy our health by accumulating in the body, toxic substances, nitrates, pesticides, heavy metals, radiation and electromagnetic radiation.

Even in our homes we are not protected from influence external factors. We live surrounded by chemicals.

Finishing materials, detergents and cleaning products are based on synthetic materials that have a carcinogenic effect on the human body. If compared with ozone holes And acid rain, then the impact on the human body of synthetic materials inside our homes is much greater and what is most terrible is their constant impact on people, albeit in small doses.

Therefore, it is hardly surprising that diseases caused by the influence of external influences on the body are becoming more and more common. These are not only ordinary allergies, but also oncological diseases such as cancer.

on the human body

What can we say about electromagnetic fields? Electrical wires intertwined our homes, trapping us in a web like a trap. Exposure to radiation puts everyone at risk of various diseases. And it is unlikely that most of us will be able to change anything in this regard. This is not possible for anyone right now.

Therefore, I want to dwell in more detail on influence electromagnetic radiation on the human body.

Agree, it’s hard to imagine modern life without household appliances: computers, television receivers, cellular communications, radiation from microwave ovens, all this creates an electromagnetic field that can continue to exist for some time even after all devices are turned off, like static electricity.

The immune, nervous, reproductive and endocrine systems are especially sensitive to the influence of electromagnetic radiation on the human body. A person’s memory deteriorates, immunity decreases, and constant pressure due to an increase in adrenaline in the blood, sexual activity decreases, in women it increases Negative influence on fetal development during pregnancy.

Those people who are constantly forced to be exposed to electromagnetic radiation most often suffer from radio wave disease. It’s not for nothing that radiologists retire very early.

What should we do if we are constantly forced to be exposed to electromagnetic influence?

Electromagnetic radiation protection

To protect workers from electromagnetic radiation, enterprises use various absorbing, reflecting materials and deflecting devices.

In everyday life, the most effective protection is distance. They also use a shungite plate called magralit, which is installed on cell phones. This greatly reduces bad influence on the brain of a person talking on a cell phone. Watch a video about the Magralit shungite plate:

How to protect yourself if you are involuntarily exposed to electromagnetic radiation? First of all, you need to know the degree of danger to human health of each household appliance. To do this, look at the table:

Rules for protection against electromagnetic radiation at home

1. When you buy household appliances, you need to check whether they meet all safety requirements and sanitary standards.
2. The lower the power of a household appliance, the safer this device is for human health.
3. It is better if household appliances are equipped automatic control at a distance (by remote control)
4. The distance from a person’s permanent location of a household appliance must be at least 1.5 meters
5. If you decide to install electric floors in your home, then choose a system with a low level of electromagnetic field.
6. If you are forced to turn on several devices that emit radiation, then try to stay in this room as little as possible.
7. Electrical wires should not be stored rolled up in rings during operation; straighten the resulting loops.
8. Read the instructions for the devices carefully. Safe distances must be indicated there.
9. The safest position is next to the computer opposite the monitor. Stay close to the sides and back of the computer. It is better to keep the distance from the monitor at 50-70cm
10. At night, be sure to turn off your computer from the network, especially in the rooms where you sleep.
11. If you are choosing a place for a bed in a room, be sure to check whether there is a computer or TV next to the wall. Walls do not protect against magnetic fields.

Sources of electromagnetic radiation, which include overhead power lines of high and ultra-high voltage, technical means radio broadcasting, television, radio relay and satellite communications, radar and navigation systems, laser beacons, household appliances - Wi-Fi, microwave ovens, etc., have significantly affected the natural electromagnetic background. In large areas, especially near the passage air lines high and ultra-high voltage power transmission lines, radio and television centers, radar installations, the strength of electric and magnetic fields has increased from two to five orders of magnitude, creating a real danger for people, animals and flora. Radio frequency electromagnetic fields steel real threat to everything living. IN Lately the term appeared - electromagnetic pollution (EMP) anthropogenic origin or electromagnetic smog), denoting a set of electromagnetic fields of various frequencies that negatively affect a person.

Targeted use of electromagnetic (EM) energy in a wide variety of applications human activity led to the fact that the existing natural geomagnetic background - electrical and magnetic fields The electromagnetic field has been added to the Earth, atmospheric electricity, radio emission from the Sun and the Galaxy artificial origin. Its level significantly exceeds the level of natural electromagnetic background. The world's energy resources double every ten years, and specific gravity electromagnetic field (EMF) variables in the electric power industry during this time increases another three times.

In contrast to the body's reactions to low-frequency EMFs, high-frequency biological effects of electromagnetic radiation are caused mainly by the thermal energy released in the irradiated tissues. Physiological mechanisms of heat transfer do not compensate for the heat production of the body that occurs under the influence of high-frequency EMF.

In the frequency range from 1.0 to 300 MHz, the mechanisms of interaction of EMF with the body are determined by both conduction current and displacement current, and at a frequency of about 1 MHz the leading role belongs to the conduction current, and at frequencies above 20 MHz - to the displacement current. Both types of current cause tissue heating. The thermal effect increases as the frequency of the external field increases. High-frequency conduction current (at a frequency of more than 10 5 Hz), unlike low-frequency conduction current, does not excite nerves and muscles. The bias current also does not cause excitation.

The wavelength at frequencies from 1.0 to 3000 MHz exceeds the size of the human body. Such fields can have both local and general effects on it. The nature of the impact is determined by whether the whole body or part of it is in the field. For more high frequencies(frequency over 3000 MHz) wavelength smaller sizes human body, which determines only the local effect of EMF. In addition, with increasing frequency, the depth of penetration of electromagnetic waves into the body decreases. The penetration depth of electromagnetic radiation into any medium is the distance at which the field amplitude decreases by e times (e = 2.718...). Having overcome this path, the electromagnetic wave retains approximately 13% of its initial intensity. The penetration depth depends not only on the frequency of the external EMF, but also on the electrical properties of the tissues into which it penetrates. For fat and bone tissue, this value is an order of magnitude greater than for muscle tissue.

Since the characteristic relaxation frequency of water falls within the frequency range of microwave radiation, it is precisely aquatic environments organisms absorb the energy of microwave fields to the greatest extent. Microwave waves interact weakly with the skin and fatty tissue, and are intensively absorbed in muscles and internal organs. Therefore, muscles and viscera undergo the greatest heating during microwave therapy. A lot of heat is generated in the liquids filling various cavities.

Microwave radiation is widely used in radar. Violation of safety precautions when working on radar installations can cause very serious damage to health.

Of particular interest are works concerning the study of the influence on the central nervous system of low-intensity microwave fields modulated in the frequency range of the biological object’s own biological rhythms. It has been established that the threshold intensities for microwave radiation modulated in this range are significantly lower than those that are characteristic of pulsed and continuous radiation.

A low-energy microwave field, modulated in the rhythm of the brain’s own frequencies, has a pronounced cardiotropic effect. By exposing brain (nervous) tissue to EMFs modulated by the frequency of the brain’s own biorhythms, it is possible to enhance the biological effect of EMFs due to resonance phenomena.

A significant role is played by resonance processes associated with biological rhythms person. Resonant strengthening or weakening of these rhythms, the appearance of harmonics and subharmonics, and the results of cross-modulation in nonlinear cell elements can give rise to various psychophysiological effects with negative consequences.

Among the many electromagnetic phenomena special attention deserve microwave radiation (MVI), and the most significant contribution to microwave pollution of the OS is made by radar and radio relay stations and other objects, the operation of which is based on the generation of EMR in the microwave range. People who work at tropospheric, satellite, radio and radar stations experience headaches, irritability, drowsiness, weakened memory, etc.

Based on the dose and nature of exposure, acute and chronic damage from microwave radiation is distinguished (Table 1). Acute lesions include disorders resulting from short-term exposure to microwave energy flux density (EFD), which causes a thermogenic effect. Chronic damage is the result of prolonged exposure to MVI subthermal PPE.

*—intensity values ​​are the lowest found in the literature.

On the part of the cardiovascular system, neurocirculatory dystonia (NCD) of the hypertensive type and myocardial dystrophy, accompanied by rapidly progressing coronary insufficiency, were observed. The peripheral blood picture was characterized by leukopenia and thrombocytopenia. Specialists servicing electromagnetic devices reveal a phase nature of changes in the peripheral circulatory system. IN initial period There may be a moderate decrease in hemoglobin and red blood cells. Subsequently, these indicators increase and sometimes significantly exceed the norm. The number of leukocytes at first tends to increase compared to the norm. After seven to nine years of contact, a tendency toward a decrease in leukocytes appears. In persons with 7-12 years of experience, persistent leukopenia is possible. Some people experience changes in their blood clotting parameters.

Biological studies have established that the most sensitive to the effects of EMR are: central nervous system, eyes, gonads. In this case, disturbances in the activity of the cardiovascular, neuroendocrine, hematopoietic, immune systems and metabolic processes. Research has shown that the human reproductive system is very sensitive to EMF radiation. At the same time, quite a lot of high percent cases of impotence, decreased testosterone in the blood. Women may experience reproductive dysfunction (toxicosis of pregnancy, spontaneous miscarriages, pathology of childbirth).

The human body is not indifferent to the localization of EM energy on certain organs (when using hand-held radiotelephones, this is the head; portable walkie-talkies, the lower back or back). There is a clear dependence of bioeffects on the field intensity, polarization and direction of waves, the ratio of the sizes of organs and the human body with the EMR wavelength. The difficulty is that it is necessary to take into account all the variety of factors that determine the amount of absorbed EM energy, dielectric properties tissues, geometry, mass, orientation of a biological object, polarization of EMF, configuration and characteristics of the source, exposure, intensity and frequency of radiation, all features of the generation and propagation of microwave EMR.

Radiation at a frequency of 900 MHz, permitted for mobile radiotelephones, has a particularly high permeability, and a “resonance effect” often occurs in the head. True, there are large differences in individual sensitivity. There are many models and modifications of radiotelephones and they differ significantly from each other in power and wavelength. Therefore, it is possible to talk about the specific impact of a particular device only after appropriate certification.

The target for microwave radiation is a molecule with EM properties. These are, first of all, water molecules. The living human body mainly (95% in infancy and 60% in old age) consists of water. All substances, when dissolved in water, form hydration shells. Weak low-frequency EMFs change metastable structures in water, which sharply reduces the concentration of potassium ions and leads to the formation of active free radicals.

EM energy of microwave radiation affecting water goes into thermal energy and subsequent bioeffects in cells and tissues are associated with an increase in their temperature locally, and then with warming up the entire organism. The greater the magnitude of the microwave wave, the deeper the thermal burn in the tissues. An increase in temperature causes excitation of thermoreceptors. Mechanoreceptors in the lesion site are also irritated due to the “volume effect” of heated tissue fluid.

Simultaneously with the thermal effect, a resonance effect also appears in the destruction of DNA molecules, ATP, and a decrease in the degree of binding of K +, Ca 2+ and other ions. The permeability of membranes for K + and Na + changes. It has been proven that the main mechanism of the influence of LF EMR on biological objects is determined by the fact that at E = 30 kV/m, every second 10 4 Na + ions are introduced into the cell and the same number of K + ions are removed, which requires an increase in energy consumption.

The share of microwave energy absorption by water is: at frequencies of 1 GHz - 50%, 10 GHz - 90%, and at 30 GHz - 98%. The effect of microwave energy absorption by cells and tissues is a thermal and non-thermal effect. The structure and functions of the nerve cell, red blood cell, and other cells are disrupted. The most intensely overheated organs are those that do not contain blood vessels(lens, testes, ovaries, etc.). In this sense, the “target organ” for microwaves is the eye, gonads and sperm.

The thermal effect spreads to the central nervous system, exciting and overexciting it. The central nervous system is affected very early due to the direct and indirect action of microwave radiation through efferent system. IN vicious circles the endocrine, immune, cardiovascular, and respiratory systems are included. In the later stages, signs of energy exhaustion and depression of brain centers occur.

With chronic exposure to microwave radiation, radio wave disease develops with disruption of the functions of all regulatory systems, as a result of which labor productivity sharply drops and mental disorders are observed. Radiation in the radio range causes a person to experience noise and whistling. More than twenty years ago, even the discovery of the effect of radio audibility was reported. Its essence is that people who were in the field of a powerful radio broadcasting station heard " inner voices", speech, music, etc.

The complex of negative EMFs is the direct cause of many diseases. Human body responds sensitively to the wave load, first with a decrease in performance, weakening of attention, emotional instability, and then an avalanche of diseases of the nervous and cardiovascular systems, most internal organs and especially the kidneys and liver.

EMF has an adverse effect on the body and, under certain conditions, can serve as a prerequisite for the formation of pathological conditions among the population exposed to its chronic effects. EMF leads to the development of aging syndrome, the signs of which are decreased performance and immunity, the presence of many diseases, early disorder cholesterol levels, inhibition of the reproductive system, development of age-related pathology in early years (hypertonic disease, cerebral atherosclerosis). The timing of the occurrence of disorders in the body when exposed to EMFs depends on many factors: frequency range, duration of exposure (work experience), localization of exposure (general or local), the nature of the EMF (modulated, continuous, intermittent) and others. Wherein significant role individual characteristics of the organism play a role. It has been experimentally proven that exposure to modulated EMFs can cause effects opposite to those of unmodulated EMFs. The use of pulsed EMF in experiments makes it possible to obtain a more pronounced biological effect than with continuous irradiation. The great biological activity of pulsed radiation is also evidenced by the greater sensitivity of the cholinergic systems of the brain to them.

IN last years It has been convincingly proven that disturbances in body functions under the influence of microwave radiation occur not only due to the formation of excess heat in tissues. Consequently, the biophysical mechanisms of the effect of EMF on biological systems cannot be reduced to the two discussed above: overheating in high-frequency fields and excitation in low-frequency fields. Currently, the attention of researchers of the biological effects of electromagnetic radiation is focused on the third mechanism. It is called specific. The most characteristic feature of the specific effect of EMF on the body is that biological systems react to radiation of extremely low intensity, insufficient for excitation and heating, but such reactions do not occur in the entire range of EMF, but at certain frequencies. Therefore, the third type of reaction biological systems on EMF also has such names as resonant and weak interactions, frequency-dependent biological effects of EMF.

FREQUENCY DEPENDENT BIOLOGICAL EFFECTS OF EMF

The frequency-dependent biological effects of EMF described to date are few and yet diverse, which makes their classification difficult.

Under the influence of microwave radiation, some bacteria (for example, E. coli) synthesize a peculiar protein - colicin, which has antigenic properties for bacteria of other strains. This is observed only at certain frequencies (from 45.6 to 46.1 GHz) at a fairly low field intensity (down to 0.1 W m-2), although colicin synthesis also occurs under the influence of other factors. The formation of a new protein is usually explained by the selective effect of such factors, including electromagnetic waves of certain frequencies, on the genetic apparatus of the cell. The authors of this hypothesis believe that among the processes of storage and transmission genetic information It is not replication and transcription that change, but translation. It is likely that microwave radiation can disrupt the normal sequence of nucleotides in messenger RNA, resulting in the production of macromolecules unusual for the cell, which are not able to ensure the full performance of the corresponding functions. The synthesis of “incomplete” proteins is reflected primarily in those substrates that are actively renewed (for example, enzymes). Such disorders are associated with changes in the level of metabolic processes and physiological activity of animals, observed by a number of researchers.

Data on the effect of electromagnetic waves on the genetic apparatus of cells are scarce, contradictory and fragmentary. Thus, human gamma globulin loses its antigenic properties when exposed to electromagnetic radiation with a frequency of 13.1 - 13.3-13.9 - 14.4 MHz on the blood. EMFs of other frequencies do not lead to a similar effect. At the same time, it can be explained without invoking the hypothesis about the effect of electromagnetic waves on the genetic apparatus. There is an assumption about the possibility of interaction of external EMFs with components of the plasma membrane of the cell. This explains the increased release of calcium ions from brain tissue exposed to low-frequency electromagnetic radiation. This phenomenon occurs only at certain frequencies (6-16 Hz). It is especially effective to use harmonic vibrations low frequency, but UHF fields modulated by low frequencies (with a modulation depth of 80-90%).

The calcium hypothesis is based on information about the structure of the plasmalemma. Many of the molecules included in its composition have finite chains of amino sugars protruding into the peri-membrane space. They form numerous areas of immobile areas on the surface of the cell membrane. negative charges, having a strong affinity for H- and Ca 2 +. These cations are adsorbed by the plasmalemma from the intercellular medium. Probably, cations fixed by the polyanionic layer of the plasmalemma of the nerve cell can provide interaction with weak EMFs. The energy of such fields is not sufficient to change the ionic permeability of the excitable membrane (that is, to activate voltage-dependent ion channels in it), but this energy may be enough to disrupt the electrostatic connection of cations with membrane amino sugars. As a result, cations leave the surface of the plasmalemma and their excess is created in the intercellular environment. According to the calcium hypothesis, this applies primarily to calcium ions. A sharp increase in the Ca 2+ gradient on the plasma membranes of CNS neurons can cause excitation because nerve cells are excited by an incoming calcium current through the plasmalemma covering their bodies.

In addition to the ionic one, membrane and dipole theories of interaction of EMFs with microstructures are also considered, within the framework of which the conversion of EMF energy into kinetic energy molecules is also associated with ideas about fluctuation-probabilistic influence, realized through trigger amplifying mechanisms of a living system.

The specific effect of EMR is explained by the nonlinear nature of the field’s influence on microstructures. The mechanism of action of microwaves is to change the membrane permeability of the cell, which leads to a change in the function of the nucleotide cyclase system, affecting the activity of redox enzymes. Metabolism products via the humoral route cause changes in the physiological state. Some authors have suggested the existence of specific receptors for the perception of EMF in animals and humans.

Electromagnetic radiation of certain (resonant) frequencies can act as signals, that is, control the release of free energy biological system without introducing significant energy from the outside into this system. The criterion for the information impact of EMF is the predominance of the energy of the body's response reactions (changes in metabolism and physiological activity) over the energy of the external field that caused them. The energy effects of EMF are characterized by the fact that the energy of the response reactions of a biological system is less than the energy introduced into it by the field.

The biological effects of weak EMFs are determined by the high selective sensitivity to them (in a narrow spectral range) of a particular cell type. Apparently, neurons are most susceptible to weak fields. Specialized electroreceptors have been found in a few representatives of the animal world. They were not found on the person. However, the absence of both electroreceptors and specific “electrical” sensations does not indicate the impossibility of human perception of weak EMFs. One of the mechanisms of selective sensitivity of brain neurons to low-frequency radiation may be their interaction with cations (for example, Ca 2+ - according to the calcium hypothesis), when they are desorbed from the plasma membranes that previously bound them.

By analogy with the principle of operation of an amplifier (a weak signal at the input controls the redistribution of significant energy at the output), the mechanisms of response of biological systems to weak EMFs are defined as amplifying (or cooperative). Weak EMFs of certain frequencies are probably capable of performing the role of a trigger signal for some biological systems. They can interact both with charges fixed on cell membrane, and so, apparently, with intracellular substrates, right down to the genetic apparatus of the cell. However, the high gradient electric potential, existing on the plasmalemma, complicates the effect of EMF on intracellular systems. For some pathological conditions level membrane potential decreases, which can lead to greater vulnerability of intracellular processes to external fields. This is probably due to increased sensitivity patients to atmospheric phenomena.

Research last decades convincingly confirmed informational role and the significance for biological systems of ultra-weak EMFs, including in the ELF range under certain laws of their modulation.

Development of the idea that electrons and EMFs, as more labile than molecules (elements of living matter), carry energy, charges and information, being a kind of fuel for life processes, led many authors to the idea of ​​the existence in the body of a system for maintaining bioelectrical homeostasis, ensuring the normal physiological state of cells. The assumption that there is a mechanism of central regulation in the body physiological processes, consistent with the periodically changing parameters of the Earth's electric and magnetic fields and designed to protect against interference from sporadically occurring intense cosmic EMFs of all frequency ranges, leads to the idea of ​​the presence in a highly organized organism sensory system, perceiving changes in the EMF of the external environment.

• influence the course of biochemical reactions of intracellular metabolism;
• influence the enzymatic activity of proteins - enzymes in the brain, liver and other structures;
• influence (directly or indirectly) the processes of transmission of genetic information (transcription and translation processes);
• influence the levels of sulfhydryl and other groups that determine the polarity of protein molecules;
• act on neurohumoral regulation, in particular on the hypothalamic-pituitary and sympathoadrenal systems;
• change the dynamics of the immune response;
• change physicochemical characteristics glia, in particular, its electron-optical density;
• rebuild the pattern of impulse flows generated by neurons;
• change the functional activity of receptors and various ion channels.

Thus, as a result of the interaction of the body with the electrical component of the EMF, biological effects of three types can occur: excitation, heating and cooperative processes. Two of them are well studied and are explained within the framework of the concept energy interaction fields with an organism. The third effect, manifested in the perception of weak electromagnetic radiation by biological systems, has not been sufficiently studied. Its origin is apparently connected with the fact that during the evolution of biological systems, EMFs of certain frequencies performed in relation to them the mission of a carrier of information about the environment. This is obvious to the world. Information function other parts of the electromagnetic spectrum has not yet been proven or truly explained.

FEATURES OF INTERACTION OF DIGITAL NOISE WITH LIVING SYSTEMS AND PROBLEMS OF EMR BIOLOGICAL SAFETY

Widespread use digital technologies led to the emergence of a new component of the human electromagnetic environment - digital noise (DN). If in general electromagnetic pollution environment is a matter of concern for environmental specialists, the possible role of the digital component as an additional risk factor has not yet been considered. The need to isolate CS from the entire spectrum of the electromagnetic background is dictated by experiments on qualitatively new features of the bioeffects of CS at the cellular level.

Implementation of any new technology associated with radiation into the space surrounding a person electromagnetic waves, is inevitably accompanied by discussions about possible health consequences. This is especially true for mobile communications, since nowadays everyone knows that microwave radiation can be far from harmless, and the radio transmitter of the subscriber device operates directly near the ear, a few centimeters from the brain. Numerous studies, however, do not yet provide a clear answer to the question: how harmful is radiation? mobile phone for its user. The complexity of the problem, insufficient funding, and lobbying of manufacturing companies contribute to the fact that in the foreseeable future one can hardly expect to obtain clear conclusions on the problem under consideration. Therefore, for a qualitative assessment possible consequences EMR exposure mobile phone on the human body, we took advantage of the laws known in electromagnetic biology, as well as some provisions of the physics of living things.

The main safety criterion is considered to be the smallness of the increased EMR dose, which is determined from the considerations that the permissible exposure limit should be with a fairly good margin below the threshold, above which noticeable changes occur in the human body. International safety standards set a limit for the so-called Specific Absorption Rate (SAR), the time derivative of the EMF energy absorbed by a unit of mass in the volume of a body of a given shape and density. Depending on local standard, various countries SAR fluctuates within 10 -2 -10 -3 W/g, which, when converted into power flux density taking into account the averaging time interval, gives –10 -3 -10 -4 W/cm 2. Such orders of magnitude are guaranteed (by approximately an order of magnitude) to exceed the radiation level values ​​obtained in model calculations and in experiments with experimental volunteers. Note, however, that all calculations and measurements refer to the carrier frequency. The relative level of radiation power outside the operating band in the microwave-eHF range does not exceed 10% and, it would seem, is even more consistent with safety standards.

It is obvious that the creators of the standards took into account only linear dependence possible biological effects from the absorbed dose, guided by the principle “the less, the safer”. This is indeed true for the so-called thermal factor, which is responsible for heating biological tissue when absorbing EMR. However, numerous experiments on the effects of microwave and EHF fields on living systems of the different levels organization - from a microbial cell to a person - indicates the fundamental nonlinearity of receptivity (in this case they talk about the “information factor”). As a result, the concept of biologically safe intensity becomes, to put it mildly, vague.

Moreover, until recently, dependence biological reaction on the intensity of radiation (monochromatic or noise-like) was considered, although nonlinear, but still monotonic. CS introduces a new quality to the bioeffects of EMR - a non-monotonic dependence: with a decrease in intensity, the effect can disappear and reappear, even showing a tendency to change sign.

Let us touch upon one more aspect of the problem under discussion, namely the question of the “benefit” or “harmfulness” of a particular EMR frequency range for the body. The microwave range is considered to be rather “harmful”, including for exceeding EMR power levels (< 10 -7 Вт\см 2). С КВЧ все не так однозначно. В частности, показано, что положительное для организма (лечебное) воздействие излучений этого участка спектра, например в техноло­гиях КВЧ –терапии, имеет место лишь при соблюдении ряда условий. А именно — сверхнизкая, порядка тепловых шумов (<10 -19 Вт/см 2), интенсивность и строго детерминированная локализация воздействия. В общем же случае, судя по многочисленным экспериментам, могут наблюдаться биоэффекты разных знаков. Это означает, что, если не впадать в излишний оптимизм, следует учитывать потенциальную опасность физиологических последствий облучения низкоинтенсивными ЭМИ, в особенности головного мозга и ушной раковины, где расположено много активных точек.

What are the features of the impact of CS on living systems? Within the framework of the concept of an endogenous coherent field that forms the integral electromagnetic framework of a living organism, the possibility of the regulating influence of a weak external signal is assumed. It is important that such an effect must be resonant and purely individual in frequency composition, reflecting the spectrum of characteristic frequencies of a particular organism. It is obvious that digital noise with its “monochromatic broadband” spectrum turns out to be a universal tool that affects any living object. Moreover, if we are guided by the idea of ​​\u200b\u200bthe “affinity” of external EMR with the body’s own fields of cells, then CS is simultaneously the initiator of both restorative (EHF range) and destructive (microwave) processes.

Each substance has a certain radiation. It occurs due to the creation of an electromagnetic field around the material and its propagation in a certain direction. The further charged particles move from their source, the stronger the electromagnetic field of the substance, and therefore the stronger the electromagnetic radiation. In this case, the described radiation has the property of attenuation, that is, the further the electron is from its source, the less charge it has. Electromagnetic radiation has a certain effect on humans. They can both treat certain diseases and cause harm.

What is electromagnetic radiation

Electromagnetic radiation refers to waves of the same name that are formed under the influence of electric and magnetic fields. From the point of view of scientists, the unit of radiation is a quantum, but at the same time it also has the properties of a wave (for example, it attenuates as the object of influence moves away).

Currently, the following types of electromagnetic radiation are distinguished:

• Radio frequency (propagates in the form of radio waves);
• Heat or infrared rays;
• Optical waves that can be detected by the naked human eye (without special instruments);
• Hard and ultraviolet radiation, which are predominantly in the ultraviolet spectrum (they are also called ionized).

Nature of radiation sources

Sources of electromagnetic radiation are classified as follows:

• Artificial, when the electromagnetic field (EMF) is disturbed by special devices or equipment, usually created by man;
• Natural, when electromagnetic radiation comes from elements of nature. Thus, all electromagnetic fields and radiation generated by the planet Earth, electrical processes occurring in the layers of the atmosphere, and nuclear reactions in the Sun are natural.

Radiation is divided according to its level into low-level and high-level. It is the power of the source of electromagnetic waves that determines the parameters of the field strength and its radiation.

High-level emitters include:

• electricity transmission lines (mainly high-voltage, transporting the bulk of electricity and creating a large EMF);
• electric transport (trolleybuses, trams, metro, running on high-current energy);
• towers necessary for transmitting television and radio signals, as well as mobile communications signals;
• transformer substations and single current converters;
• lifting equipment that operates using an electromechanical power plant.

Examples of low-level sources of electromagnetic radiation are almost all household appliances, in particular:

• laptops, televisions and other devices equipped with a cathode ray tube display;
• irons, refrigerators, air conditioners and so on;
• low-current networks that ensure the transfer of energy from a source to various devices and equipment (the cables themselves, sockets, meters and other types of related devices).

In some cases, high-level electromagnetic radiation is necessary. For example, in medicine, where X-ray machines, MRI machines and other diagnostic tools generate a large one-time dose of radiation to the human body, but this is necessary for diagnosing or treating certain diseases.

Human electromagnetic field

The human body is not only a good conductor for electromagnetic waves, but also generates EMF itself, being a natural source of electromagnetic radiation (EMR). Oscillations of the bioelectric field are actively used to diagnose various diseases. For example, electrocardiograms and electroencephalograms make it possible to identify problems with the circulatory system, cardiovascular diseases, brain diseases, and so on in the early stages.

Attempts to measure the human electromagnetic field were made by scientists back in the 18th century, but without the availability of appropriate equipment that would have the necessary level of sensitivity, this was not possible. All studies were limited to only analyzing the effect of EMR on people.

A breakthrough in this matter was made thanks to discoveries in the physics of superconductivity, most of which occurred in the 60s of the last century. As a result of their introduction into science, instruments appeared that made it possible to more accurately measure the influence of the electromagnetic field on humans and to record the EMR itself of humans and other living organisms. This gave impetus to the development of a new branch of science - biomagnetism, which studied the EMF of animals and people, characterized by minimal values, as well as their influence on various natural processes.

The presence of a person’s own electromagnetic field harmonizes the functioning of all cells of the body. Some scientists call the EMF of people a biofield or aura. This area is studied by psychics. From their point of view, it is the biofield that is the body’s main defense against the negative influences of the external environment, including emotional ones. As soon as problems arise in the biofield, a person begins to get sick, he experiences various troubles, so it must be immediately restored, for which unconventional methods are used.

Effect of EMR on humans

In the process of research, scientists have found that prolonged exposure to electromagnetic waves on the human body can lead to various diseases, not all of which are curable. In most cases, a critical dose of EMR radiation can lead to pathological changes in human organs. The most disappointing conclusion is that changes as a result of exposure to EMF occur at the level of the genetic code, that is, the consequences can affect the children of the exposed person.

This state of affairs is explained by the fact that EMF has high biological activity, and this has an extremely negative effect on any living organisms. The level of exposure depends on three factors:

• the type of radiation in the field of which the person was;
• duration of stay at the radiation source;
• intensity or power of EMR.

The influence of electromagnetic waves on human health can be general or local. Thus, being close to a high-voltage power line, the entire body is irradiated; the effect of EMF occurs on all organs and on all parts of the body. A mobile phone, on the contrary, affects only those parts of the body or sensory organs near which it is located. Therefore, it is not recommended to talk on the phone for a long time to avoid high doses of radiation to the brain.

In addition to electromagnetic effects, there is also a temperature effect of EMF on living organisms. Since EMI is formed due to the movement of electrons along conductors in a certain direction, and the conductor has a certain resistance, as a result of the formation of EMF, the temperature of the conductor increases. This principle is used in microwave emitters, which convert electrical energy into heat, creating temperatures that allow metal to melt and other complex operations. However, this equipment has a significant side effect due to the high power of EMR and, accordingly, its impact on the tissues of human organs.

Important to remember! In everyday life, people also encounter EMR. This happens when using household appliances, mobile phones, traveling on electric vehicles, and so on. EMR is not removed from the body; it accumulates, which leads to diseases of the nervous system or brain. To avoid such developments, it is recommended to measure electromagnetic radiation in the apartment and periodically monitor its value.

Since EMR is of a wave nature, its influence on an object decreases with increasing distance, so it is enough to be at a safe distance from the source, and this will significantly reduce its negative impact.

Radiation protection

To avoid the described negative impact of EMR on the body, various methods of protection are actively used. In production, for example, protective screens are used that absorb radiation and significantly reduce its impact on humans. It is almost impossible to build such a structure at home, so household protection against EMP is based on the following recommendations:

1. You should be as far away from the radiation source as possible. So, for a power transmission line, the safe distance is 25 meters, for a monitor with a beam tube - only 30 cm. It is not recommended to bring mobile phones closer to your head than 2.5 cm. This makes conversation almost impossible, so a better recommendation would be to reduce negotiation time;
2. It is recommended to periodically measure the EMR level of used household appliances and monitor their operating time. This is especially true for children who often play computer games for a long time, thereby being exposed to radiation. Protection from electromagnetic radiation is the responsibility of parents, so you should set a clear mode for playing computer games or watching TV and strictly control it;
3. When the device is not in use, it must be turned off, since the device continues to generate EMF and radiate radiation while it is turned on. It will also make family members safer and healthier.

So, electromagnetic radiation brings both benefits and harm. Even a person himself emits waves of a certain frequency and power; they can be detected using special equipment. The greatest benefit from EMR is achieved in medicine, where it is used for diagnosis and treatment. However, constant exposure to radiation can lead to negative consequences in the human body, so high-quality protection from electromagnetic fields and radiation is required. In production it is organized in a special way, but in everyday life it is enough to follow a few simple recommendations.

Modern science has divided the material world around us into matter and field.

Does matter interact with the field? Or maybe they coexist in parallel and electromagnetic radiation does not affect the environment and living organisms? Let's find out how electromagnetic radiation acts on the human body.

The duality of the human body

Life on the planet originated under the influence of an abundant electromagnetic background. For thousands of years this background has not undergone significant changes. The influence of the electromagnetic field on various functions of a wide variety of living organisms was stable. This applies both to its simplest representatives and to the most highly organized creatures.

However, as humanity “matured,” the intensity of this background began to continuously increase due to artificial man-made sources: overhead power transmission lines, household electrical appliances, radio relay and cellular communication lines, and so on. The term “electromagnetic pollution” (smog) arose. It is understood as the totality of the entire spectrum of electromagnetic radiation that has a negative biological effect on living organisms. What is the mechanism of action of electromagnetic fields on a living organism, and what could be the consequences?

In search of an answer, we will have to accept the concept that a person not only has a material body consisting of an unimaginably complex combination of atoms and molecules, but also has another component - an electromagnetic field. It is the presence of these two components that ensures a person’s connection with the outside world.

The impact of the electromagnetic web on a person’s field affects his thoughts, behavior, physiological functions and even vitality.

A number of modern scientists believe that diseases of various organs and systems occur due to the pathological effects of external electromagnetic fields.

The spectrum of these frequencies is very wide - from gamma radiation to low-frequency electrical vibrations, so the changes they cause can be very diverse. The nature of the consequences is influenced not only by the frequency, but also by the intensity and time of exposure. Some frequencies cause thermal and informational effects, others have a destructive effect at the cellular level. In this case, decomposition products can cause poisoning of the body.

Norm of electromagnetic radiation for humans

Electromagnetic radiation turns into a pathogenic factor if its intensity exceeds the maximum permissible norms for humans, verified by many statistical data.

For radiation sources with frequencies:

Radio and television equipment, as well as cellular communications, operate in this frequency range. For high-voltage transmission lines, the threshold value is 160 kV/m. When the intensity of electromagnetic radiation exceeds the specified values, negative health effects are very likely. The actual voltage values ​​of the power line are 5–6 times less than the dangerous value.

Radio wave disease

As a result of clinical studies that began back in the 60s, it was found that under the influence of electromagnetic radiation on a person, changes occur in all the most important systems in his body. Therefore, it was proposed to introduce a new medical term - “radio wave disease”. According to researchers, its symptoms are already spreading to a third of the population.

Its main manifestations - dizziness, headaches, insomnia, fatigue, poor concentration, depression - are not particularly specific, so diagnosing this disease is difficult.

However, later these symptoms develop into serious chronic diseases:

• cardiac arrhythmia;
• fluctuations in blood sugar levels;
• chronic respiratory diseases, etc.

To assess the degree of danger of electromagnetic radiation for humans, let’s consider its effect on different systems of the body.

Impact of electromagnetic fields and radiation on the human body

1. The human nervous system is very sensitive to electromagnetic effects. Nerve cells of the brain (neurons) as a result of the “interference” of external fields deteriorate their conductivity. This can provoke severe and irreversible consequences for the person himself and his environment, since the changes affect the holy of holies - higher nervous activity. But it is she who is responsible for the entire system of conditioned and unconditioned reflexes. In addition, memory deteriorates, coordination of brain activity with the work of all parts of the body is disrupted. Mental disorders, including delusions, hallucinations and suicide attempts, are also very likely. Violation of the body's adaptive ability is fraught with exacerbation of chronic diseases.
2. The reaction of the immune system to exposure to electromagnetic waves is very negative. Not only does the immune system become suppressed, but the immune system also attacks its own body. This aggression is explained by a drop in the number of lymphocytes, which should ensure victory over the infection invading the body. These “valiant warriors” also become victims of electromagnetic radiation.
3. Blood quality plays a paramount role in human health. What is the effect of electromagnetic radiation on blood? All elements of this life-giving liquid have certain electrical potentials and charges. Electrical and magnetic components that form electromagnetic waves can cause destruction or, conversely, adhesion of red blood cells, platelets, and cause obstruction of cell membranes. And their effect on the hematopoietic organs causes disruptions in the functioning of the entire hematopoietic system. The body's reaction to such a pathology is the release of excessive doses of adrenaline. All these processes have a very negative effect on the work of the heart muscle, blood pressure, myocardial conductivity and can cause arrhythmia. The conclusion is not comforting - electromagnetic radiation has an extremely negative effect on the cardiovascular system.
4. The effect of an electromagnetic field on the endocrine system leads to stimulation of the most important endocrine glands - the pituitary gland, adrenal glands, thyroid gland, etc. This causes disruptions in the production of important hormones.
5. One of the consequences of disorders in the nervous and endocrine systems is negative changes in the sexual sphere. If we evaluate the degree of influence of electromagnetic radiation on male and female sexual function, then the sensitivity of the female reproductive system to electromagnetic influences is much higher than that of men. Associated with this is the danger of affecting pregnant women. Pathologies of child development at different stages of pregnancy can manifest themselves in a decrease in the rate of fetal development, defects in the formation of various organs, and even lead to premature birth. The first weeks and months of pregnancy are especially vulnerable. The embryo is still loosely attached to the placenta and an electromagnetic “shock” can interrupt its connection with the mother’s body. In the first three months, the most important organs and systems of the growing fetus are formed. And the misinformation that external electromagnetic fields can bring can distort the material carrier of the genetic code - DNA.

How to reduce the negative impact of electromagnetic radiation

The listed symptoms indicate the strongest biological influence of electromagnetic radiation on human health. The danger is aggravated by the fact that we do not feel the impact of these fields and the negative effect accumulates over time.

How to protect yourself and your loved ones from electromagnetic fields and radiation? Following the following recommendations will help minimize the consequences of using electronic household appliances.

Our everyday life includes more and more diverse technology that makes our lives easier and more beautiful. But the influence of electromagnetic radiation on humans is not a myth. The champions in terms of influence on humans are microwave ovens, electric grills, cell phones and some models of electric shavers. It is almost impossible to refuse these benefits of civilization, but we should always remember about the reasonable use of all the technology around us.

Continuous industrial progress and rapid development of science in the modern era have led to the widespread use of various household electrical appliances and electronic equipment. This creates great convenience for people in work, study and everyday life, and, at the same time, causes hidden harm to their health.

Science has proven that all consumer electronics, when used, generate electromagnetic waves of different frequencies to varying degrees. Electromagnetic waves are colorless, odorless, invisible, intangible, but at the same time they have great penetrating power, so that a person is defenseless against them. They have already become a new source of environmental pollution, gradually eroding the human body, negatively affecting human health, causing various diseases.

Electronic radiation has already become a new environmental disaster on a global scale.
To date, four International Congresses have been held around the world on the effects of low and ultra-low radiation on human health. The issue is recognized as so urgent that the problem of “electronic smog” has been put by the World Health Organization (WHO) in first place in terms of the danger of impact on human health. WHO considers “the current level of modern electromagnetic radiation and its impact on the population to be more dangerous than the effect of residual nuclear ionizing radiation.”

The International Commission on Non-Ionizing Radiation Protection of the countries of the European Union recommends that the governments of all states take the most effective preventive and technical means and measures to protect the population from the effects of “electromagnetic smog.” Special literature published in our country and abroad indicates the following manifestations of the harmful effects of electromagnetic radiation on the human body:

1. a gene mutation that increases the likelihood of cancer;
2. disturbances in the normal electrophysiology of the human body, which causes headaches, insomnia, tachycardia;
3. eye damage causing various ophthalmological diseases, in severe cases – up to complete loss of vision;
4. modification of signals sent by hormones of the parathyroid glands on cell membranes, inhibition of bone growth in children;
5. disruption of the transmembrane flow of calcium ions, which interferes with the normal development of the body in children and adolescents;
6. the cumulative effect that occurs with repeated harmful exposure to radiation ultimately leads to irreversible negative changes.

Biological effects of electromagnetic fields

Experimental data from both domestic and foreign researchers indicate high biological activity of EMF in all frequency ranges. At relatively high levels of irradiating EMF, modern theory recognizes a thermal mechanism of action. At a relatively low level of EMF (for example, for radio frequencies above 300 MHz it is less than 1 mW/cm2), it is customary to talk about the non-thermal or informational nature of the impact on the body. Numerous studies in the field of biological effects of EMF will allow us to determine the most sensitive systems of the human body: nervous, immune, endocrine and reproductive. These body systems are critical. The reactions of these systems must be taken into account when assessing the risk of EMF exposure to the population.
The biological effect of EMF under conditions of long-term exposure accumulates over many years, resulting in the development of long-term consequences, including degenerative processes of the central nervous system, blood cancer (leukemia), brain tumors, and hormonal diseases. EMFs can be especially dangerous for children, pregnant women (embryos), people with diseases of the central nervous, hormonal, and cardiovascular systems, allergy sufferers, and people with weakened immune systems.

Effect on the immune system

Currently, sufficient data have been accumulated indicating the negative impact of EMF on the immunological reactivity of the body. The results of research by Russian scientists give reason to believe that when exposed to EMF, the processes of immunogenesis are disrupted, more often in the direction of their inhibition. It has also been established that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. The occurrence of autoimmunity is associated not so much with a change in the antigenic structure of tissues, but with the pathology of the immune system, as a result of which it reacts against normal tissue antigens. According to this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The influence of high-intensity EMF on the body’s immune system is manifested in a suppressive effect on the T-system of cellular immunity. EMFs can contribute to nonspecific inhibition of immunogenesis, increased formation of antibodies to fetal tissues and stimulation of an autoimmune reaction in the body of a pregnant female.

Effect on the nervous system

A large number of studies carried out in Russia, and the monographic generalizations made, give grounds to classify the nervous system as one of the most sensitive systems in the human body to the effects of EMFs. At the level of the nerve cell, structural formations for the transmission of nerve impulses (synapse), at the level of isolated nerve structures, significant deviations occur when exposed to low-intensity EMF. Higher nervous activity and memory change in people who have contact with EMF. These individuals may be prone to developing stress reactions. Certain brain structures have increased sensitivity to EMF. Changes in the permeability of the blood-brain barrier can lead to unexpected adverse effects. The nervous system of the embryo exhibits particularly high sensitivity to EMF.

Effect on sexual function

Sexual dysfunction is usually associated with changes in its regulation by the nervous and neuroendocrine systems. Related to this are the results of work on studying the state of gonadotropic activity of the pituitary gland under the influence of EMF.

Repeated exposure to EMF causes a decrease in the activity of the pituitary gland

Any environmental factor that affects the female body during pregnancy and affects embryonic development is considered teratogenic. Many scientists attribute EMF to this group of factors.
Of primary importance in teratogenesis studies is the stage of pregnancy during which EMF exposure occurs. It is generally accepted that EMFs can, for example, cause deformities by acting at different stages of pregnancy. Although there are periods of maximum sensitivity to EMF. The most vulnerable periods are usually the early stages of embryo development, corresponding to the periods of implantation and early organogenesis.

An opinion was expressed about the possibility of a specific effect of EMF on the sexual function of women and on the embryo. A higher sensitivity to the effects of EMF of the ovaries than the testes was noted. It has been established that the sensitivity of the embryo to EMF is much higher than the sensitivity of the maternal body, and intrauterine damage to the fetus by EMF can occur at any stage of its development. The results of epidemiological studies will allow us to conclude that the presence of contact of women with electromagnetic radiation can lead to premature birth, affect the development of the fetus and, finally, increase the risk of developing congenital deformities.

Effect on the endocrine system and neurohumoral response

In the works of Russian scientists back in the 60s, in the interpretation of the mechanism of functional disorders under the influence of EMF, the leading place was given to changes in the pituitary-adrenal system. Studies have shown that under the influence of EMF, as a rule, stimulation of the pituitary-adrenaline system occurred, which was accompanied by an increase in the content of adrenaline in the blood and activation of blood coagulation processes. It was recognized that one of the systems that is early and naturally involved in the body's response to the influence of various environmental factors is the hypothalamic-pituitary-adrenal cortex system. The research results confirmed this position.

The earliest clinical manifestations of the consequences of exposure to EM radiation on humans are functional disorders of the nervous system, manifested primarily in the form of autonomic dysfunctions, neurasthenic and asthenic syndrome. Persons who have been in the area of ​​EM radiation for a long time complain of weakness, irritability, fatigue, weakened memory, and sleep disturbances.

Often these symptoms are accompanied by disorders of autonomic functions. Disorders of the cardiovascular system are manifested, as a rule, by neurocirculatory dystonia: lability of pulse and blood pressure, tendency to hypotension, pain in the heart, etc. Phase changes in the composition of peripheral blood (lability of indicators) are also noted with the subsequent development of moderate leukopenia, neuropenia, erythrocytopenia . Changes in the bone marrow are in the nature of a reactive compensatory stress of regeneration. Typically, these changes occur in people who, due to the nature of their work, were constantly exposed to EM radiation with a fairly high intensity. Those working with MF and EMF, as well as the population living in the area affected by EMF, complain of irritability and impatience. After 1-3 years, some people develop a feeling of internal tension and fussiness. Attention and memory are impaired. There are complaints about low sleep efficiency and fatigue. Considering the important role of the cerebral cortex and hypothalamus in the implementation of human mental functions, it can be expected that long-term repeated exposure to maximum permissible EM radiation (especially in the decimeter wavelength range) can lead to mental disorders.
