Technological progress also has a downside. The global use of various electrically powered equipment has caused pollution, which has been given the name - electromagnetic noise. In this article, we will consider the nature of this phenomenon, the degree of its impact on the human body and protective measures.

What is it and sources of radiation

Electromagnetic radiation is electromagnetic waves that occur when a magnetic or electric field is disturbed. Modern physics interprets this process within the framework of the theory of corpuscular-wave dualism. That is, the minimum portion of electromagnetic radiation is a quantum, but at the same time it has frequency-wave properties that determine its main characteristics.

The frequency spectrum of the electromagnetic field radiation makes it possible to classify it into the following types:

• radio frequency (these include radio waves);
• thermal (infrared);
• optical (that is, visible to the eye);
• radiation in the ultraviolet spectrum and hard (ionized).

A detailed illustration of the spectral range (electromagnetic emission scale) can be seen in the figure below.

Nature of radiation sources

Depending on the origin, sources of radiation of electromagnetic waves in world practice are usually classified into two types, namely:

• perturbations of the electromagnetic field of artificial origin;
• radiation from natural sources.

Radiations coming from the magnetic field around the Earth, electrical processes in the atmosphere of our planet, nuclear fusion in the depths of the sun - all of them are of natural origin.

As for artificial sources, they are a side effect caused by the operation of various electrical mechanisms and devices.

The radiation emanating from them can be low-level and high-level. The degree of intensity of the electromagnetic field radiation completely depends on the power levels of the sources.

Examples of high EMP sources include:

• Power lines are usually high-voltage;
• all types of electric transport, as well as the accompanying infrastructure;
• television and radio towers, as well as mobile and mobile communication stations;
• installations for converting the voltage of the electrical network (in particular, waves emanating from a transformer or distribution substation);
• elevators and other types of lifting equipment where an electromechanical power plant is used.

Typical sources emitting low-level radiation include the following electrical equipment:

• almost all devices with a CRT display (for example: a payment terminal or a computer);
• various types of household appliances, ranging from irons to climate systems;
• engineering systems that provide electricity to various objects (it means not only a power cable, but related equipment, such as sockets and electricity meters).

Separately, it is worth highlighting the special equipment used in medicine, which emits hard radiation (X-ray machines, MRI, etc.).

Impact on a person

In the course of numerous studies, radiobiologists came to a disappointing conclusion - prolonged radiation of electromagnetic waves can cause an "explosion" of diseases, that is, it causes the rapid development of pathological processes in the human body. Moreover, many of them introduce violations at the genetic level.

Video: How electromagnetic radiation affects people.

This is due to the fact that the electromagnetic field has a high level of biological activity, which negatively affects living organisms. The influence factor depends on the following components:

• the nature of the radiation produced;
• how long and with what intensity it continues.

The impact on human health of radiation, which has an electromagnetic nature, directly depends on the localization. It can be both local and general. In the latter case, large-scale irradiation occurs, for example, radiation produced by power lines.

Accordingly, local irradiation refers to the impact on certain parts of the body. Electromagnetic waves emanating from an electronic watch or a mobile phone are a vivid example of a local effect.

Separately, it is necessary to note the thermal effect of high-frequency electromagnetic radiation on living matter. The field energy is converted into thermal energy (due to the vibration of molecules), this effect is the basis for the operation of industrial microwave emitters used to heat various substances. Unlike benefits in industrial processes, thermal effects on the human body can be detrimental. From the point of view of radiobiology, it is not recommended to be near "warm" electrical equipment.

It must be taken into account that in everyday life we ​​are regularly exposed to radiation, and this happens not only at work, but also at home or when moving around the city. Over time, the biological effect accumulates and intensifies. With the growth of electromagnetic noise, the number of characteristic diseases of the brain or nervous system increases. Note that radiobiology is a rather young science, therefore, the harm caused to living organisms from electromagnetic radiation has not been thoroughly studied.

The figure shows the level of electromagnetic waves produced by conventional household appliances.

Note that the field strength level decreases significantly with distance. That is, in order to reduce its effect, it is enough to move away from the source at a certain distance.

The formula for calculating the norm (rationing) of electromagnetic field radiation is indicated in the relevant GOSTs and SanPiNs.

Radiation protection

In production, absorbing (protective) screens are actively used as a means of protecting against radiation. Unfortunately, it is not possible to protect yourself from electromagnetic field radiation using such equipment at home, since it is not designed for this.

• in order to reduce the impact of electromagnetic field radiation to almost zero, you should move away from power lines, radio and television towers at a distance of at least 25 meters (you must take into account the power of the source);
• for a CRT monitor and a TV, this distance is much smaller - about 30 cm;
• electronic watches should not be placed close to the pillow, the optimal distance for them is more than 5 cm;
• as for radios and cell phones, bringing them closer than 2.5 centimeters is not recommended.

Note that many people know how dangerous it is to stand near high-voltage power lines, but at the same time, most people do not attach importance to ordinary household electrical appliances. Although it is enough to put the system unit on the floor or move it away, and you will protect yourself and your loved ones. We advise you to do this, and then measure the background from the computer using an electromagnetic field radiation detector in order to visually verify its reduction.

This advice also applies to the placement of the refrigerator, many put it near the kitchen table, practical but unsafe.

No table will be able to indicate the exact safe distance from a particular electrical equipment, since emissions may vary, both depending on the model of the device and the country of manufacture. At the moment there is no single international standard, therefore, in different countries, the norms may have significant differences.

You can accurately determine the intensity of radiation using a special device - a fluxmeter. According to the standards adopted in Russia, the maximum allowable dose should not exceed 0.2 μT. We recommend measuring in the apartment using the above-mentioned device for measuring the degree of electromagnetic field radiation.

Fluxmeter - a device for measuring the degree of radiation of an electromagnetic field

Try to reduce the time when you are exposed to radiation, that is, do not stay close to working electrical appliances for a long time. For example, it is not at all necessary to constantly stand at the electric stove or microwave oven while cooking. Regarding electrical equipment, you can see that warm does not always mean safe.

Always turn off electrical appliances when not in use. People often leave various devices turned on, not considering that at this time electromagnetic radiation is emitted from electrical equipment. Turn off your laptop, printer or other equipment, it is unnecessary to be exposed to radiation once again, remember about your safety.

Mechanism of EMR influence

The human body, like any organism on Earth, has its own electromagnetic field, thanks to which all systems, organs and cells of the body work harmoniously. Human electromagnetic radiation is also called a biofield. The visual representation of the biofield, which some people see, and which can be built by a computer with the help of special devices, is also called an aura.

This field is the main protective shell of our body from the influence of external electromagnetic fields. When it is destroyed, the organs and systems of our body become easy prey for any disease-causing factors.

If other sources of radiation, much more powerful than the radiation of our body, act on our natural electromagnetic field, then it is distorted or even begins to collapse. And chaos begins in the body. This leads to disruption of the work of various organs and systems - diseases.

That is, for any person it is obvious that, for example, a buzzing transformer box or a powerful electric generator are dangerous, because they create a strong electromagnetic field around them. Safety time and distance standards have been calculated for workers when they are near such devices. But here's what is NOT obvious to most people:

The same effect of destruction of the biofield occurs when exposed to weak electromagnetic radiation, if the body is under their influence regularly and for long periods of time.

That is, the sources of danger are the most common household appliances that surround us every day. Things without which we can no longer imagine our lives: household appliances, computers, laptops, mobile phones, transport and other attributes of modern civilization.

In addition, a large crowd of people, the mood of a person and his attitude towards us, geopathogenic zones on the planet, magnetic storms, etc. have a significant impact on us. (for more details see page ).

Among scientists, there are still disputes about the dangers of electromagnetic radiation. Some say that it is dangerous, others, on the contrary, do not see any harm. I would like to clarify.

The most dangerous is not the electromagnetic waves themselves, without which no device could really work, but their information component, which cannot be detected by conventional oscilloscopes.

It has been experimentally established that electromagnetic radiations have a torsion (information) component. According to the studies of specialists from France, Russia, Ukraine and Switzerland, it is torsion fields, and not electromagnetic ones, that are the main factor in the negative impact on human health. Since it is the torsion field that transmits to a person all that negative information, from which headaches, irritations, insomnia, etc. begin.

How strong is the impact of the technology around us? We offer several videos for viewing:

How dangerous radiation surrounds us? Visual demonstration:

Of course, these are far from all the dangerous items that we use on a daily basis. More information about radiation sources can be found on the page:

Effect of electromagnetic radiation on human health

Weak electromagnetic fields (EMFs) of high frequency with a power of hundredths and even thousandths of a watt are dangerous for a person because the intensity of such fields coincides with the intensity of the radiation of the human body during the normal functioning of all systems and organs in his body. As a result of this interaction, a person's own field is distorted, which contributes to the development of various diseases, especially in the most weakened parts of the body.

The most dangerous property of such effects is that they accumulate over time in the body. As they say: "a drop of water wears away a stone." In people who, by occupation, use a lot of various equipment - computers, telephones - a decrease in immunity, frequent stress, a decrease in sexual activity, and increased fatigue were found.

And if we take into account the development of wireless technologies and the miniaturization of gadgets that allow us not to part with them around the clock... Today, almost every resident of the metropolis, who is somehow exposed to mobile and Wi-Fi networks, power lines, electric transport, etc., is at risk around the clock. .

The problem is that the danger is invisible and intangible, and begins to manifest itself only in the form of various diseases. At the same time, the cause of these diseases remains outside the field of view of medicine. With rare exceptions. And while you are healing the symptoms with the achievements of modern medicine, our invisible enemy stubbornly continues to undermine your health.

The most affected by electromagnetic fields are the circulatory system, brain, eyes, immune and reproductive systems. Someone will say: “So what? Surely this impact is not so strong - otherwise international organizations would have sounded the alarm long ago.

Facts:

Do you know that within 15 minutes after starting to work on the computer in a 9-10 year old child, changes in the blood and urine almost coincide with changes in the blood of a person with cancer? Similar changes appear in a 16-year-old teenager after half an hour, in an adult - after 2 hours of work at the monitor.

(we are talking about cathode ray monitors, which are gradually disappearing from everyday use, but are still found)

US researchers found:

• in most women who worked on computers during pregnancy, the fetus developed abnormally, and the probability of miscarriage approached 80%;
• brain cancer in electricians develops 13 times more often than in workers of other professions;

Effect of electromagnetic radiation on the nervous system:

The level of electromagnetic radiation, even without causing thermal effects, can affect the most important functional systems of the body. Most experts consider the nervous system to be the most vulnerable of them. The mechanism of action is very simple - it has been established that electromagnetic fields disrupt the permeability of cell membranes for calcium ions. As a result, the nervous system begins to malfunction. In addition, an alternating electromagnetic field induces weak currents in electrolytes, which are the liquid constituents of tissues. The range of deviations caused by these processes is very wide - during the experiments, changes in the EEG of the brain, a slowdown in reaction, memory impairment, depressive manifestations, etc. were recorded.

Effect of EMR on the immune system:

The immune system is also affected. Experimental studies in this direction have shown that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. There is reason to believe that under the influence of EMR, the processes of immunogenesis are disturbed, more often in the direction of their suppression. This process is associated with the emergence of autoimmunity. In accordance with this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The effect of high-intensity EMF on the body's immune system is manifested in a depressing effect on the T-system of cellular immunity.

Effect of EMR on the endocrine system:

The endocrine system is also a target for EMR. Studies have shown that under the action of EMF, as a rule, stimulation of the pituitary-adrenal system occurred, which was accompanied by an increase in the content of adrenaline in the blood, activation of blood coagulation processes. It was recognized that one of the systems that early and naturally involves the body's response to various environmental factors is the hypothalamus-pituitary-adrenal cortex system.

Effect of electromagnetic radiation on the cardiovascular system:

You can also note the violations of the cardiovascular system. It manifests itself in the form of lability of the pulse and blood pressure. Phase changes in the composition of peripheral blood are noted.

The influence of electromagnetic radiation on the reproductive system:

1. There is a suppression of spermakinesis, an increase in the birth rate of girls, an increase in the number of congenital malformations and deformities. The ovaries are more sensitive to the influence of electromagnetic radiation.
2. The female genital area is more susceptible to the effects of electromagnetic fields generated by computers and other office and household appliances than the male.
3. Vessels of the head, thyroid gland, liver, genital area are critical areas of influence. These are only the main and most obvious consequences of EMP exposure. The picture of the real impact on each individual is very individual. But to one degree or another, these systems are affected by all users of household appliances at different times.

Effect of electromagnetic radiation on pregnant women and children:

The children's organism has some peculiarities in comparison with an adult, for example, it has a large ratio of the length of the head and the body, and a greater conductivity of the medulla.

Due to the smaller size and volume of the head of a child, the specific absorbed power is greater than that of an adult, and the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in adults. With the growth of the head and the thickening of the bones of the skull, the content of water and ions decreases, and hence the conductivity.

It has been proven that growing and developing tissues are most susceptible to the adverse effects of an electromagnetic field, and active human growth occurs from the moment of conception until about 16 years of age.

Pregnant women also fall into this risk group, since EMF is biologically active in relation to embryos. When a pregnant woman talks on a cell phone, virtually her entire body is exposed to EMF, including the developing fetus.

The sensitivity of the embryo to damaging factors is much higher than the sensitivity of the maternal organism. It has been established that intrauterine damage to the fetus by EMF can occur at any stage of its development: during fertilization, crushing, implantation, organogenesis. However, the periods of maximum EMF sensitivity are the early stages of embryonic development—implantation and early organogenesis.

Facts:

In the Neurodiagnostic Research Institute in Spain in 2001, they found that in 11-13-year-old children who talked on a cell phone for two minutes, the change in the bioelectrical activity of the brain persisted for another two hours after they hung up.

The University of Bristol in the UK ended a study last year showing a significant increase in reaction time in 10-11 year old children who used a GSM mobile phone. Similar results were obtained by the Finns at the University of Turku, who observed a group of children 10-14 years old.

In the USSR, until the 1990s, a large number of studies of the biological effect of EMF on the developing animal organism were carried out.

It has been established that even low EMF intensities affect the embryonic development of offspring. The offspring of irradiated animals are less viable, developmental anomalies, deformities, lag in weight, dysfunctions of the higher parts of the central nervous system (slow production and reduced ability to maintain defensive and motor-food conditioned reflexes), and a shift in the pace of postnatal development are observed.

EMF-irradiated adult animals are characterized by a decrease in the number of offspring, changes in the genital organs of females, disturbances in the development of the fetus, a decrease in the percentage of interbreeding, and statistically more frequently observed cases of stillbirth.

A study of the effect of EMF on the offspring of rats exposed to electromagnetic effects in parameters similar to what a human embryo receives when its mother talks on a cell phone showed that, compared with the control, the embryonic mortality of the offspring is statistically significantly increased, the mass of the thymus gland is reduced, and the number of developmental anomalies is increased internal organs, for the first 4 weeks of the postnatal period, the mortality of the offspring of rats of all experimental groups was 2.5-3 times higher than in the control, and body weight was lower. The development of rat pups also went worse: the formation of sensory-motor reflexes, the timing of the cutting of incisors lagged behind, in female rat pups formation was disturbed.

The sensitivity of living systems to external electromagnetic oscillations of the biosphere, first of all, depends on the frequency range and intensity of oscillations. The range of electromagnetic phenomena conditionally available for study is divided into three areas, within which there are specific features of the interaction of electromagnetic fields with biological systems:

low-frequency fields (up to approximately meter wavelengths)
Microwave - meter, decimeter and centimeter waves
EHF - millimeter and submillimeter waves.

Electromagnetic waves carry a certain energy and when they interact with matter, this wave energy is converted into heat.

The latter is also an important condition for the vital activity of various living creatures of the biosphere. At low doses of irradiation with electromagnetic waves in the human body, no significant physiological changes occur. However, electromagnetic waves of any frequency with an irradiation power density exceeding 10 W/cm are harmful to living organisms.

The response of a living system to external electromagnetic influences can occur at various structural levels of a living organism - from the molecular, cellular to the level of the whole organism.

The nature of the interaction of an electromagnetic wave with a living organism is determined both by the characteristics of the radiation itself (frequency or wavelength, phase propagation velocity, oscillation coherence, wave polarization, etc.), and by the physical properties of a given biological object as a medium in which the wave propagates. These properties of a substance include dielectric constant, electrical conductivity, wave penetration depth, etc.

Nowadays, the biological effect of electromagnetic waves in the range from constant magnetic fields to visible light (the region of non-ionizing radiation) has begun to be studied very intensively. However, the results of these studies are known only to a narrow circle of specialists, and, as a rule, the rest of the public lives quietly and peacefully according to its own laws. To some extent, this was led to the widespread opinion among the people that since a person does not feel the electromagnetic waves noted above the range, then they do not affect a person at all.

The action of low-frequency electromagnetic waves

For a long time, it was believed that low-frequency electromagnetic fields (EMF), up to the slowly changing magnetic and electric fields of the Earth, do not have any noticeable effect on living organisms. This belief was based on the fact that the biological effects associated with the transformation of the energy of these very weak fields in the tissues of living organisms are negligible. However, in the last decade it has become clear that these low-frequency electromagnetic fields play a significant role in the functioning of wildlife. At the same time, the concept arose that living organisms have evolved to use low-frequency electromagnetic fields to obtain information about changes in the external environment, for information communications between organisms and within living organisms.

In addition, an assumption is also made about the possible influence of fields at ultra-low frequencies, when its frequency is in the infra-low range of 10-3-10 Hz, close to the most important biological rhythms. Indeed, the rhythms of the electrical activity of the brain, heart and other organs are essentially in that same frequency interval

Action of millimeter waves

Why does millimeter wave electromagnetic radiation have a specific effect on living organisms?

The answer to this question is as follows: millimeter radiation of extraterrestrial origin is strongly absorbed by the Earth's atmosphere. Therefore, living organisms could not have natural mechanisms of adaptation to fluctuations of noticeable intensity in this range due to external causes. However, they could adapt to their own similar fluctuations.

In the last 30 years, a purposeful study of the influence of millimeter electromagnetic waves on living organisms has been carried out.

Original studies in this direction have been carried out, and quite interesting and experimental data have been obtained by scientists N. D. Devyatkov, M. B. Golont, N. P. Didenko, V. I. Gaiduk, Yu. P. Kalmykov and others (Russia), Sitko S.P. (Ukraine), Caylman F. and Grundler V. (Germany), Berto A. (France) and others. An analysis of the experimental material accumulated to date allows us to draw two conclusions:

1. Electromagnetic oscillations of low intensity in the millimeter wavelength range have a significant impact on the vital activity of various organisms.

2. Two interrelated effects are found, which differ in the presence or absence of frequency dependences of resonant absorption.

Non-resonance effects are associated with water molecules (H2O) in irradiated organisms, which strongly absorb millimeter radiation. Indeed, water performs extremely important functions in the life of biological objects and the human body.

For example, a flat layer of water only 1 mm thick attenuates radiation at X ~ 8 mm by a factor of 100, and at X ~ 2 mm by a factor of 10,000. Therefore, when human skin is irradiated with millimeter waves, almost all radiation is absorbed in surface layers a few tenths of a millimeter thick, since the weight content of water in the skin is more than 65%. The absorption of millimeter radiation by water molecules in the body is explained by the fact that the frequencies of their rotational movements are largely in the region of millimeter and submillimeter wavelengths. This absorbed energy is then converted into heat.

In addition, scientists obtained a unique experimental result: when millimeter radiation interacts with biological objects, well-reproducible resonance absorption curves were found. The frequency dependence of this interaction effect is very similar in shape to the resonant characteristic of an oscillatory circuit. For example, the human body can be considered as a good antenna for electromagnetic waves with a frequency of 70-100 MHz; that at these frequencies it "resonates" with the field.

At present, there is no generally accepted point of view explaining the nature of this phenomenon. The question of the mechanisms of the sharply resonant action of millimeter radiation on living organisms is, perhaps, one of the interesting questions in the problem under discussion, which excites the minds of scientists and is the subject of numerous discussions in the scientific literature, at seminars and conferences.

Action of radio waves

At the dawn of the development of radio broadcasting, electromagnetic waves of the radio frequency range for the human body were considered safe. But radio engineering developed, powerful radiation generators appeared, and then scientists discovered that radio waves primarily act on the central nervous system.

The biological effect of radio waves of all ranges is similar, however, with an increase in the frequency of field oscillations, its pathogenic effect increases, reaching the greatest severity in microwave radio waves. In mild cases, due to the so-called non-thermal action, mainly functional disorders occur in the body, which can accumulate with repeated exposure to the microwave field. Irradiation of high intensity gives a thermal effect, leading to persistent changes in the nervous system.

Another case is related to the emission of so-called "radio-wave hearing" - a phenomenon known since 1947. Very often, when microwave impulses act on the head, a person hears "clicks" in time with the impulses; moreover, he has the impression that clicks are heard inside the head. This phenomenon takes place if the power flux density of the pulsed radiation is high enough (about 500 kW/m2).

The action of the visible spectrum of electromagnetic waves

Opening our eyes every morning, we do not think what a miracle it is to see the world around us and its inescapable beauty. Prose can also be added to our computer age: more than 80% of the information entering the "central processing unit" of the human body goes through the main sensory (sensitive) video terminal - the eyes.

The sensitivity of the human eye to light is very high. He is able to perceive and large light fluxes. These fluxes exceed the smallest luminous flux that the eye perceives by trillions of times.

Our organ of vision also allows us to distinguish colors, that is, to perceive radiation differently depending on its spectral composition.

With the same power of the light flux, the yellow-green rays will be perceived by the eye as the brightest, and red and purple will seem the weakest. If the brightness of yellow-green light with a wavelength of X ~ 0.555 µm is taken as unity, then the brightness of blue light of the same power will be 0.2; and the brightness of the red light is 0.1 of the brightness of the yellow-green flux. Even powerful fluxes of radiation with a wavelength shorter than 0.3 microns and longer than 0.9 microns are not perceived by the human eye. The maximum sensitivity of the eye on the wavelength of the light entering it coincides with the maximum emissivity of the Sun.

Even the great Goethe noticed that yellow evokes bright feelings, blue - causes a feeling of cold, lilac - something bleak, and red - creates a whole range of impressions. Further research by a number of generations of scientists made it possible to use the color spectrum for the treatment and prevention of many diseases. An analysis of these numerous observations and the results of specially designed experiments leads to the following conclusions:

Red color stimulates the nerve centers, the left hemisphere, energizes the liver and muscles. However, prolonged exposure can cause fatigue and increased heart rate. Red color is contraindicated in case of fever, nervous excitement, hypertension, inflammatory processes, neuritis, it also has a bad effect on bright red-haired people.

Yellow and lemon colors activate motor centers, generate energy for muscles, stimulate the liver, intestines, skin, have laxative and choleretic effects, and cause a joyful mood. These colors are contraindicated in case of elevated body temperature, neuralgia, overexcitation, inflammatory processes and visual hallucinations.

Green color eliminates spasms of blood vessels and lowers blood pressure, dilates capillaries, stimulates the pituitary gland, promotes good mood.

The blue color, on the contrary, promotes vasospasm and increases blood pressure, and therefore is contraindicated in hypertension. Has antimicrobial activity. Used for disinfection of premises, treatment of diseases of the ear, throat and nose, gastrointestinal tract. However, it should be remembered that dark blue color with prolonged exposure to a person can cause fatigue and depression.

Indications and contraindications for purple in the clinic are about the same as for blue.

High voltage action

Recently, it has been suggested that children living near high-voltage power lines (power lines) are more at risk of contracting certain types of cancer, in particular leukemia. True, there is no direct evidence from medicine. Nevertheless, the results of epidemiological studies conducted in Sweden, Finland, Denmark and the USA (Poisk, 1995, No. 9) still suggest that high-voltage power lines and various electric power plants can affect the incidence of leukemia and brain tumors in children. Directly under the wires of power lines, even at a minimum voltage of 220 V, the intensity of electromagnetic radiation exceeds the norm of 0.5 kW/m2. Indeed, if you go out to the power line clearing, you can see green grass and bright flowers, but there will be no bees on them. They are the most sensitive to electromagnetic waves.

Cell phone: good or bad?

A cell phone is an extremely convenient means of communication that is rapidly conquering "living space". According to experts' forecasts, the number of people (network subscribers) using it in Russia will exceed 1 million, and by the year 2000 - 3 million. not only the benefits, but also the safety for the health of users. Today, there is practically no discussion among scientists about whether or not a cell phone affects a person's health. The accumulated knowledge about the influence of the electromagnetic field (EMF) on the human body allows us to unambiguously say that the electromagnetic radiation of a cell phone, like any other source of EMF, affects the physiological state and health of a person who is in contact with it.

The area of ​​irradiation during the operation of a cell phone is primarily the brain, peripheral receptors of the vestibular, visual and auditory analyzers. When using cell phones with a carrier frequency of 450-900 MHz, the wavelength slightly exceeds the linear dimensions of the human head. In this case, the radiation is absorbed unevenly and so-called hot spots can form, especially in the center of the head. Calculations of the absorbed energy of the electromagnetic field in the human brain show that when using a 0.6 W cell phone with an operating frequency of 900 MHz, the “specific” field energy in the brain is from 120 to 230 μW/cm2 (the standard in Russia for cell phone users is 100 µW/cm2). So, it can be expected that long-term repeated exposure to maximum permissible doses of radiation (especially in the decimeter wavelength range) can lead to significant changes in the bioelectrical activity of various brain structures and disorders of its functions (for example, the state of short-term and long-term memory).

Special experiments by Russian scientists have shown that the human brain not only senses the electromagnetic radiation of a cell phone, but also distinguishes between cellular communication standards. The results of the experiment indicate significant changes in the bioelectrical activity of the human brain. In the majority of testers, both during and after irradiation with electromagnetic waves of a cell phone, the a-band of the bioelectrical activity of the brain increased in the spectra of the electroencephalogram. These changes were especially pronounced immediately after the field was turned off. Other parameters (pulse rate, respiration, electromyogram, tremor, blood pressure) did not respond to exposure to the electromagnetic field of the radiotelephone.

Cell phone radiation is complex modulated. One of the components of the signal of all radiotelephones is low-frequency (for example, in the GSM / DCS-1800 system it is 2 Hz). But it is low (1-15 Hz) frequencies that correspond to the rhythms of the human brain, which exceed other rhythms of the electrical activity of a healthy person in intensity. It has been proven that modulated EMFs can selectively suppress or enhance these biorhythms.

The complex mode of modulation of electromagnetic waves of a cell phone makes us think about allergy sufferers: some of them suffer from exceptionally high susceptibility to electromagnetic fields in certain modulation modes already at a low dose of radiation (1-4 μW/cm2). This should be taken into account when intending to use a cell phone. This warning is also important: people talking on a cell phone inside a car are at particular risk. If the antenna of the device is inside the metal body of the car, then it serves as a resonator and greatly enhances the dose of absorbed radiation.

Apparently, no amount of warnings will be able to stop the rapid growth in the number of cellular subscribers. That is why experts around the world see their task in developing clear recommendations for creating a new generation of equipment operating in the so-called gentle mode of exposure.

Meanwhile, radiotelephones are only a small part of the cellular communication system. Its basis is formed by stationary radio transmitters - the so-called base stations (BC). The more aircraft in the system, the more reliable and stable the connection. In particular, there are already more than 500 aircraft in the Moscow region.

Can such a concentration of emitters pose a danger to the population?

According to the recommendations of the Center for Electromagnetic Safety at the Institute of Biophysics of the Russian Academy of Sciences (general director of the center, Doctor of Medical Sciences, Professor Yuri Grigoriev), nothing threatens the residents of the house where the aircraft is installed. Cellular antennas radiate in a narrow sector directed away from the house. Repeated measurements, which were carried out in the course of studying the electromagnetic situation in Moscow and the Moscow region, show that regardless of the transmitter's affiliation and its mode of operation, even on the top floor of the house in the immediate vicinity of the emitter, the level of the electromagnetic field does not exceed the background. You can get a certain dose if you just climb onto the roof and stand right in the path of the signal. This should not be done.

As for the neighboring houses, the field strength in them is indeed slightly higher than the background one. However, it does not exceed 0.1-0.5 shares of the maximum permissible level (MPL). So the residents of neighboring houses also have nothing to fear. Moreover, Russian electromagnetic safety standards are the most stringent in the world.

For comparison: in the United States, the maximum remote control ranges from 300 to 1000 μW/cm2, depending on the radiation frequency, while in our country it is only 10 μW/cm2.

If the reader wants to know exactly whether the operation of a particular cellular transmitter is allowed, then you should contact the city (republican) center for sanitary and epidemiological surveillance. There you can also see the results of control measurements of the electromagnetic field in your homes.

4.8. Influence of radiation from television towers

Specialists of the Center for Electromagnetic Safety measured the level of electromagnetic radiation in the apartments of houses located near the Ostankino TV tower. In many surveyed premises, an excess of the maximum permissible level (MPL) by one and a half to two times was found.

The document entitled "Sanitary rules and regulations for the protection of the population from electromagnetic fields of radio transmitting objects" establishes for the population the maximum permissible level of EMP in the range of 30-300 MHz as follows: the intensity of the alternating electric field created by radio engineering objects should not exceed 2 V / m for residential buildings of any kind, children's, educational institutions and other premises intended for round-the-clock stay of people. Experts recommend that the level of electromagnetic radiation in residential premises near TV towers should be reduced not to the maximum control level (2 V/m), but to values ​​corresponding to the average background level - less than 0.1 V/m. This "hard" approach is due to the fact that the development of pathological reactions of a particular organism is significantly affected by the amount of absorbed EMR energy, the modulation mode, the duration of its exposure, and such parameters as age and lifestyle.

Therefore, it is very difficult to talk about a safe level. It is different for different people. In addition, an important fact is the possibility of accumulation of the biological effect of EMR under conditions of prolonged exposure (ie, the effect of cumulation). As a result of this process, there is a possibility of such a distant pathology as functional disorders of the nervous system, changes in hormonal status and, as a result, the development of a tumor process. Children and embryos developing in the womb are especially sensitive to the effects of EMR. All this leads to the need to minimize human contact with EMR, and in some cases completely eliminate this additional burden on the human body.

Russia is the first country where studies of the effects of EMR on the nervous system were started. In 1966, in the monograph of Professor Yu.A. Kholodov "The influence of electromagnetic and magnetic fields on the central nervous system" described the direct effect of radiation on the brain, changes in the function of the blood-brain barrier, the effect on neuron membranes, memory, conditioned reflex activity, described the psychophysiological reactions of a person, chronic depression syndrome. Today it can be considered an established fact that even low-intensity EMF exposure causes a tendency to develop stress reactions and memory impairment.

With the constant development of high technologies, an increasing number of sources of harmful rays appear that surround man and nature from all sides. The issues of electromagnetic radiation and its influence on the human body are being discussed today by world-class scientists.

It is not possible to completely limit oneself from exposure to harmful radiation, but it is possible and necessary to prevent their excess, it is enough to understand what it is.

One of the proven facts of the impact of the electromagnetic field is its negative impact not only on human health, but also on his thoughts, behavior and even the psychological component. Scientists came to this conclusion after studying the long-term interaction of waves with the human body. The sources of these waves are all kinds of electronic devices, computer, WI-FI, power lines and much more.

Thus, based on research, experts have revealed the theory that developing diseases and pathologies in the human body take place due to the influence of rays from the outside. Moreover, decay products can even cause poisoning of body cells. Fortunately, a person can protect himself and his loved ones from harmful waves by knowing the elementary methods of protection against electromagnetic radiation.

Types of electromagnetic radiation are divided into radio waves, infrared (thermal) radiation, visible (optical) radiation, ultraviolet and hard radiation. IMPORTANT: in this case, the answer to the question “does visible light belong to electromagnetic radiation” is positive.

radio wave sickness

By the beginning of the 60s, specialists managed to discover a new trend in medicine - radio wave disease. The spectrum of distribution of this disease is very wide - 1/3 of the population. It cannot be said that in most cases a person is exposed to waves against his will. However, radio wave disease is already indicated by a number of symptoms, including:

• headache;
• dizziness;
• increased fatigue;
• sleep disturbance;
• depression;
• distraction of attention.

Since such symptoms apply to many varieties of diseases, diagnosing the above becomes extremely problematic. But, like any disease, radio wave is able to develop and progress.

As a result of its spread throughout the body, a person runs the risk of developing cardiac arrhythmias, chronic respiratory diseases, and even fluctuations in blood sugar levels. This happens through the destruction of the electromagnetic field of a person, affecting even the cells of his body.

This disease manifests itself in different ways depending on the organ or system that it affects:

1. Nervous system - we are talking about a deterioration in the conductivity of neurons - nerve cells of the brain that are susceptible to electromagnetic radiation that affects a person. Thus, a deformation occurs in their work, which leads to a violation of conditioned and unconditioned reflexes, a deterioration in the functioning of the limbs, the appearance of hallucinations, and irritability. There are cases of suicide attempts against the background of a developing disease.
2. Immune system - in this case, immunity suppression occurs. And the cells responsible for its protection are themselves susceptible to the influence of electromagnetic waves, thus creating an additional negative influence from all sides.
3. Blood - electrical frequencies provoke the adhesion of blood cells to each other, contributing to the deterioration of blood outflow, the formation of blood clots. Thus, an extra release of adrenaline into the body can occur, which in itself is detrimental to health. There is no need to talk about a violation of the cardiovascular system - an obvious arrhythmia, the development of plaques in the heart muscle and other types of heart failure, as a negative effect of electromagnetic waves on the human body.
4. Endocrine system - since this system is responsible for controlling the functioning of hormones in the body, the influence of electromagnetic fields speaks for itself. The derivative of this influence is the destruction of the liver.
5. Reproductive system - often women are more affected by electromagnetic radiation than men. Possessing increased sensitivity to external influences, the female body is able to literally "suck" harmful radiation. This effect is especially dangerous during pregnancy. In the first weeks, the fetus is not strongly attached to the placenta, so there is a high probability of losing contact with the mother with a sharp release of radiation. With regards to later dates, the statistics are such that electromagnetic radiation affects the change in the genetic code of the child, the deformation of DNA.

Consequences of EMP

Radio wave sickness annually acquires new forms, expanding and progressing, depending on the number and level of radiation sources. Experts have identified a number of consequences not only individually, but also in a large-scale sense:

• Cancer is no secret that oncological diseases manifest themselves under completely different conditions. However, scientists have proven an increase in the negative effects of electromagnetic radiation on cancer cells. Thus, studies in Japan have confirmed the presence of an increased risk of childhood leukemia in people whose bedrooms literally “glow” from the presence of electrical appliances and their components.
• Violation of the psyche - in recent years, cases of deterioration in the perception of the surrounding world have become more frequent in those exposed to an excessive level of electromagnetic radiation. This is not only about the so-called classic symptoms, but also about the developing fear of EMR. Such fear often develops into a phobia, a person begins to panic at the thought that any emission of radiation can provoke pain in one or another organ or part of the body.
• Stillbirth - according to official data, today the risk of fetal death increases by 15%, provided that the mother is in constant contact with sources of electromagnetic radiation. In addition to stillbirth, the likelihood of developing pathologies in an unborn child increases, slowing down in development, premature birth, miscarriage. Such is the impact of electromagnetic radiation on human health and future generations.

In addition to the huge negative effect of electromagnetic radiation on the human body, these waves can poison the environment. The most susceptible areas include areas with a large accumulation of high-frequency power lines. Often they are located far from residential buildings, however, in individual cases, there is the presence of such power lines near settlements.

The flora and fauna are also exposed to the negative effects of harmful rays. In turn, a person eats irradiated animals and food products and, as a result, receives an additional dose of radiation-infected particles into his body. Such a process is extremely difficult to control due to factors beyond human control, but it is still possible to influence it.

Facts

To understand what constitutes the effect of electromagnetic fields on the human body, it is enough to familiarize yourself with the following facts:

1. Changes in the blood and urine of a 9-year-old child 15 minutes after sitting at the computer coincide with changes in the analyzes of a cancer patient. Teenagers are subject to similar influence after half an hour of being near the computer. And an adult undergoes a change in the analyzes after 2 hours.
2. The signal coming from a portable radiotelephone is able to penetrate the brain at a distance of up to 37.5 mm.
3. Electricians are 13 times more likely to develop brain cancer than other professions. The level of the magnetic field in such workers is practically destroyed.
4. A 13-year-old child who talks on the phone for about 2 minutes undergoes a bioelectrical brain change that takes place several hours after the conversation.
5. Animals, even slightly irradiated with a dose of electromagnetic radiation, began to lag behind in development, acquired pathologies in the body, as with radiation.

The electromagnetic emission standards have the following meanings:

• Radio waves - ultrashort (0.1mm-1m/30MHz-300GHz), short (10-100m/3MHz-30MHz), medium (100m-1km/300kHz-3MHz), long (1km-10km/30kHz-300kHz), extra long (more than 10 km / less than 30 kHz).
• Optical radiation - ultraviolet (380-10nm/7.5*10V 14stHz-3*10V 16stHz), visible radiation (780-380nm/429THz-750THz), infrared radiation (1mm-780nm/300GHz-429THz) .
• Ionizing electromagnetic radiation - X-ray, gamma. A more detailed table of calculations of EMP norms includes additional sources of propagation of harmful waves.

It is not possible to completely protect yourself from the effects of harmful waves. However, today there are a number of factors that can prevent the excessive influence of electromagnetic radiation on the human body:

1. Acquisition of a special dosimeter. Such a detector will help to calculate the most dangerous sources of radiation by calculating the frequency of their waves and, as a result, reduce the time spent near such sources or eliminate them completely. Devices for measuring electromagnetic fields are available at any household store.
2. Separation of radiation sources by area. It is not recommended to operate electromagnetic devices in a close radius between each other, otherwise their negative impact on the environment and the human body increases, causing maximum harm.
3. Isolation of radiation sources. We are talking, for example, about the refrigerator. It is advisable to use it at a distance from the dining table. A similar situation with a computer or laptop: the distance to the place of deployment (sofa, bed) should be at least one and a half meters.
4. Exclusion of toys with EMP. The electromagnetic effect of radio-controlled and electrical attributes for a children's room poses a serious threat to the health of an adult, and is extremely destructive for children. It is recommended to rid the room of EMP-radiated toys.
5. Radiotelephone isolation. This technique is capable of emitting harmful waves to a radius of up to 10 meters. It is extremely important to remove such electronics as far as possible. This method of protection will protect against the main source of harmful radiation, since the radiotelephone operates 24 hours a day.
6. Avoid buying counterfeit phones. The low price of such goods is due to the harmful radiation of electromagnetic waves per person in the first place.
7. Careful selection of household appliances. In this case, we are talking directly about devices with a steel case.

In addition to the above factors, there are well-known simple methods of protection against electromagnetic radiation, the observance of which will also allow you to protect yourself from EMP, reducing the risk of exposure to the lowest indicator:

• It is not recommended to be near a working microwave oven, since its waves have an extremely negative impact on the environment, if we take household appliances in comparison.
• It is undesirable to be too close to the monitor.
• Excluded being close to high-frequency power lines.
• It is recommended to avoid an increased amount of jewelry on the body, which is desirable to remove before going to bed.
• Approved the presence of electrical appliances, analog household appliances, appliances and wiring at a distance of 2 meters from the bed.
• A minimum amount of time near working electrical appliances and similar equipment is recommended.
• It is undesirable to find idle devices in the on state.

Often, people do not attach much importance to the harm that electromagnetic radiation can cause the most common household appliances and other factors surrounding them, because they are not able to see their waves. This feature makes EMR extremely dangerous for the life of all living things.

Having the ability to accumulate in the body, harmful rays affect the vital systems, manifesting themselves in a variety of diseases and ailments. The whole scale of this problem will be able to be seen by mankind a generation later - only then will a specific impact on the health of those who happened to live their lives surrounded by EMR sources be indicated.
