The negative impact of electromagnetic radiation. The influence of electromagnetic radiation on humans. Methods of protection against electromagnetic radiation

The biological effects of EMR exposure can manifest themselves in various forms: from minor functional changes to disorders that indicate the development of an obvious pathology. The reason for the biological effect of EMR on the body is the absorption of electromagnetic wave energy by tissues.

In general, the absorption of EMR energy depends on the oscillation frequency and the electrical and magnetic properties of the medium. The shorter the wavelength and the higher the frequency of oscillations, the more energy carries a quantum of electromagnetic radiation. The relationship between energy Y and oscillation frequency f (wavelength λ) is defined as

where c is the speed of electromagnetic waves, m/s (in air c = 3*10 8),

h is Planck's constant, equal to 6.6 * 10 34 W / cm 2.

With equal EMR characteristics, the absorption coefficient in tissues with a high water content is about 60 times higher than in tissues with a low content.

A consequence of the absorption of EMR energy is the thermal effect. Excess heat released in the human body is removed by increasing the load on the thermoregulation mechanism. Starting from a certain limit, the body cannot cope with the removal of heat from individual organs, and their temperature may rise. Exposure to electromagnetic radiation is especially harmful to tissues with an underdeveloped vascular system or insufficient blood circulation (eyes, brain, kidneys, stomach, gallbladder and bladder). Eye exposure can cause clouding of the lens (cataract). In addition to cataracts, exposure to EMR can cause corneal burns.

The thermal effect depends on the intensity of irradiation. The threshold intensities of the thermal effect of EMF on the animal's body decrease with an increase in the frequency of EMF. For example, the threshold energy flux density for the UHF range is 40 µW/cm 2 , and for the microwave range it is 10 µW/cm 2 . EMF with an intensity less than the threshold does not have a thermal effect on the body, but according to a number of theories it has a specific non-thermal effect. Data relating to the non-thermal effects of electromagnetic radiation on humans, on this moment are not complete. This is due to the lack of clear criteria for this impact, accessible to direct instrumental control.

The degree and nature of the impact of EMR on the human body is determined by the frequency of radiation, the duration of exposure, the intensity of the EMF, the size of the irradiated surface, and the individual characteristics of a person.

For long-term exposure to EMI of various frequency ranges at moderate intensity (above MPD) characteristic is the development of functional disorders in the central nervous system with mildly pronounced shifts in endocrine-metabolic processes and blood composition. In this regard, headaches, a decrease or increase in blood pressure, neuropsychiatric disorders, and the rapid development of fatigue may appear. Possible hair loss, brittle nails, weight loss. There are changes in the excitability of the visual, vestibular, olfactory analyzers. At an early stage, the changes are reversible; with continued exposure to EMR, a persistent decrease in performance occurs.

In emergency situations and extremely high levels of EMP acute disorders occur, accompanied by cardiovascular disorders with fainting, a sharp increase in heart rate and a decrease in blood pressure.

electromagnetic radiation, the levels of which do not exceed the MPC, but exceed the background ones, can be considered as a stress factor. Under the influence of such electromagnetic radiation, significant functional changes in the state of the cardiovascular and nervous systems are noted. Subjectively, a person has increased irritability, fatigue, headaches, sleep and memory disorders. In this regard, cell phones and computers, as well as various household radio-electronic and electrical appliances, have recently been of particular concern to specialists in the field of electromagnetic security.

Within the radio wave range, the highest activity of the microwave field has been proven compared to HF and UHF.

The human body has its own electromagnetic field, like any organism on earth, thanks to which all the cells of the body work harmoniously. Human electromagnetic radiation is also called the biofield (its visible part is the aura). Do not forget that this field is the main protective shell of our body from any negative influence. Destroying it, 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, begin to act on our electromagnetic field, then chaos begins in the body. This leads to a drastic deterioration in health.

And such sources can be not only household appliances, mobile phones and transport. 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.

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.

It is not the electromagnetic waves themselves that are dangerous, 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 precisely torsion fields, and not electromagnetic, 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.

Weak electromagnetic fields (EMF) with a power of hundredths and even thousandths of a watt of high frequency are dangerous for humans 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, provoking the development of various diseases, mainly in the most weakened parts of the body.

The most negative property of electromagnetic signals is that they tend to accumulate over time in the body. In people who by occupation use a lot of various office equipment - computers, telephones (including mobile phones) - a decrease in immunity, frequent stress, a decrease in sexual activity, and increased fatigue were found. And that's not all the negative impact of electromagnetic radiation!

Sources of negative radiation:

• Geopathic zones
• Sociopathogenic radiation: the influence of people on each other
• Mobile communications and cell phones
• Computers and laptops
• TV
• Microwaves (microwave oven)
• Transport
• Psychotronic weapons

The problem is that the danger is invisible and intangible, and begins to manifest itself only in the form of various diseases.

The most affected by electromagnetic fields are the circulatory system, brain, eyes, immune and reproductive systems.

The imperceptible influence of electromagnetic radiation every day and every minute is on our eyes and brain, gastrointestinal tract and genitourinary system, blood-forming organs and immune system. Someone will say: "So what?"

Data:

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.

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.

The endocrine system is also a target for EMR. Studies have shown that under the action of EMF, as a rule, the pituitary-adrenal system was stimulated, 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, created by computers and other office and household appliances than men's.
3. Vessels of the head, thyroid gland, liver, genital area are critical zones 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.

The influence of EMR in photographs of the human biofield:

You can find out how these pictures were taken.

The human biofield is in a normal state.

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.

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 a metropolis is at risk, one way or another exposed to mobile and Wi-Fi networks, power lines, electric transport, etc. .

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.

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 electro magnetic field, and active growth of a person occurs from the moment of conception to about 16 years.

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.

Data:

At the Neurodiagnostic scientific institute in Spain in 2001 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 persists for another two hours after they hang up.

The University of Bristol in the UK completed 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 90s, a large number of studies of the biological effect of EMF on the developing organism of animals.

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 are observed. nervous system(slow development and reduced ability to maintain defensive and motor-food conditioned reflexes), a shift in the pace of postnatal development.

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.

Total:

IN last years due to the development of technology, the human body is exposed to a high level of exposure to electromagnetic radiation (EMR), which could not but cause serious concern around the world.

What is the effect on living organisms? Their consequences depend on which category of radiation - ionizing or not - they belong to. The first type has a high energy potential, which acts on the atoms in the cells and leads to a change in their natural state. It can be deadly as it causes cancer and other diseases. Non-ionizing radiation includes electromagnetic radiation in the form of radio waves, microwave radiation and electrical vibrations. Although it cannot change the structure of the atom, its influence can lead to irreversible consequences.

Invisible danger

Publications in the scientific literature have raised the issue of adverse effects on individuals and society as a whole of non-ionizing EMF radiation emanating from power, electrical and wireless devices in everyday life, at work, in educational and public institutions. Despite numerous problems in establishing compelling scientific evidence for harm and gaps in elucidating the exact mechanisms of harm, epidemiological analysis is increasingly suggesting the significant potential for traumatic effects produced by non-ionizing radiation. Protection against electromagnetic radiation is becoming more and more important.

Due to the fact that medical education does not focus on the condition environment However, some physicians are not fully aware of the potential health problems associated with EMR and, as a result, manifestations of non-ionizing radiation may be misdiagnosed and treated ineffectively.

If the possibility of damage to tissues and cells associated with exposure to X-rays is beyond doubt, then the impact of electromagnetic radiation on living organisms, when they come from power lines, mobile phones, electrical appliances and some machines, has only recently begun to attract attention as a potential threat. health.

electromagnetic spectrum

Refers to a type of energy that emanates or radiates far beyond its source. Electromagnetic radiation energy exists in various forms, each with different characteristics. physical properties. They can be measured and expressed in terms of frequency or wavelength. Some waves have a high frequency, others have a medium frequency, and still others have a low frequency. The range of electromagnetic radiation includes many different forms of energy from various sources. Their name is used to classify EMP types.

The short wavelength of electromagnetic radiation, corresponding to a high frequency, is a characteristic of gamma rays, x-rays, and ultraviolet radiation. More spectrum include microwave radiation and radio waves. Light radiation belongs to the middle part of the EMR spectrum, it provides normal vision and is the light that we perceive. Infrared energy is responsible for human perception of heat.

Most forms of energy such as X-rays, ultraviolet and radio waves are invisible and imperceptible to humans. Their detection requires the measurement of electromagnetic radiation using special instruments, and as a result, people cannot assess the degree of exposure to energy fields in these ranges.

Despite the lack of perception, the action of high frequency energy, including x-rays, called ionizing, is potentially dangerous for human cells. By changing the atomic composition of cellular structures, breaking chemical bonds and by inducing the formation of free radicals, sufficient exposure to ionizing radiation can damage the genetic code in DNA or cause mutations, thereby increasing the risk of cancer or cell death.

Anthropogenic EMR

The influence of electromagnetic radiation on the body, especially non-ionizing, which is called forms of energy with lower frequencies, has been underestimated by many scientists. It was not considered to produce adverse effects at normal exposure levels. Recently, however, there is a growing body of evidence that suggests that some frequencies of non-ionizing radiation can potentially cause biological harm. Most of the studies on their impact on health have dealt with the following three main types of anthropogenic EMR:

• the lower scale of electromagnetic radiation from power lines, electrical appliances and electronic equipment;
• microwave and radio emissions from wireless communications devices such as cell phones, cell towers, antennas, and television and radio towers;
• electrical pollution due to the operation of certain types of equipment (for example, plasma TVs, some energy-saving appliances, variable speed motors, etc.) that produce signals whose electromagnetic frequency is in the range of 3-150 kHz (propagated and re-radiated by wiring).

Ground currents, sometimes called stray currents, are not limited by wires. Current follows the path of least resistance and can pass through any available path, including ground, wires, and various objects. Accordingly, electrical voltage is also transmitted through the ground and through building structures through metal water or sewer pipes, as a result of which non-ionizing radiation enters the immediate environment.

EMR and human health

While studies examining the negative properties of electromagnetic radiation have sometimes yielded conflicting results, the diagnosis of reproductive dysfunction and cancer predisposition seems to confirm suspicions that EMF exposure may pose a threat to human health. Poor pregnancy outcomes, including miscarriages, stillbirths, preterm births, sex ratio changes, and congenital anomalies, have all been linked to maternal exposure to EMR.

A large prospective study published in the journal Epidemiology, for example, reports peak EMR exposure in 1,063 pregnant women in the San Francisco area. The participants in the experiment wore magnetic field detectors, and the scientists found a significant increase in fetal mortality as the level of maximum EMF exposure increased.

EMR and cancer

Claims that intense exposure to certain frequencies of EMR can be carcinogenic have been examined. For example, the International Journal of Cancer recently published an important case-control study on the relationship between childhood leukemia and magnetic fields in Japan. By assessing the level of electromagnetic radiation in the bedrooms, scientists have confirmed that high levels exposures lead to a significantly greater risk of developing childhood leukemia.

Physical and psychological impact

People with electromagnetic hypersensitivity often suffer from exhaustion, which can affect any part of the body, including the central nervous system, musculoskeletal system, gastrointestinal tract, and endocrine system. These symptoms often lead to constant psychological stress and fear of being exposed to EMR. Many patients become incapacitated just thinking that an invisible wireless signal at any time and in any place can provoke painful sensations in their body. Constant fear and preoccupation with health problems affect well-being up to the development of a phobia and fear of electricity, which in some cause a desire to leave civilization.

Mobile phones and telecommunications

Cell phones transmit and receive signals using EMF, which is partially absorbed by their users. Since these sources of electromagnetic radiation are usually in close proximity to the head, this feature has led to concerns about possible adverse influence their use on human health.

One of the problems of extrapolating the results of their application in experimental studies in rodents is that the frequency of maximum absorption of RF energy depends on body size, shape, orientation, and position.

Resonance absorption in rats is in the range of microwave and operating frequencies of mobile phones used in experiments (from 0.5 to 3 GHz), but on the scale of the human body it occurs at 100 MHz. This factor can be taken into account when calculating the absorbed dose rate, but is a problem for those studies that use only the external field strength to determine the level of exposure.

The relative depth of penetration in laboratory animals is larger compared to the size of the human head, and tissue parameters and the mechanism of heat redistribution differ. Another potential source of inaccuracies in exposure levels is the exposure of the cell to RF radiation.

The effect of high-voltage radiation on people and the environment

Power lines with voltages above 100 kV are the most powerful sources of electromagnetic radiation. Research radiation exposure for technical personnel started with the beginning of the construction of the first 220-kV transmission lines, when there were cases of deterioration in the health of workers. The commissioning of 400 kV power lines led to the publication of numerous works in this area, which later became the basis for the adoption of the first regulations limiting the effect of a 50-Hz electric field.

Power lines with a voltage of more than 500 kV have an impact on the environment in the form of:

• electric field with a frequency of 50 Hz;
• radiation;
• magnetic field of industrial frequency.

EMF and the nervous system

The mammalian blood-brain barrier is composed of endothelial cells associated with barrier zones as well as adjacent pericytes and extracellular matrix. Helps maintain a highly stable extracellular environment necessary for accurate synaptic transmission and protects neural tissue from damage. Increasing its low permeability to hydrophilic and charged molecules can be detrimental to health.

The ambient temperature exceeding the limits of thermoregulation in mammals increases the permeability of the blood-brain barrier for macromolecules. Neuronal absorption of albumin in different areas of the brain depends on its temperature and manifests itself when it rises by 1 °C or more. Since sufficiently strong radio frequency fields can lead to tissue heating, it is logical to assume that the effect of electromagnetic radiation on a person results in an increased permeability of the blood-brain barrier.

EMF and sleep

The upper scale of electromagnetic radiation has some effect on sleep. This topic has become relevant for several reasons. Among other symptoms, complaints of sleep disturbances have been mentioned in anecdotal reports of people who believe they are being affected by EMR. This has led to speculation that electromagnetic fields could interfere with normal sleep patterns, with consequent health consequences. The potential risk of sleep disturbance should be considered given that it is a very complex biological process controlled by the central nervous system. And although the exact neurobiological mechanisms have not yet been established, the regular alternation of states of wakefulness and rest is a necessary requirement for ensuring correct operation brain, metabolic homeostasis and immune system.

In addition, sleep seems to be exactly that physiological system, the study of which will make it possible to find out the effect of high-frequency electromagnetic radiation on a person, since in this biological state the body is sensitive to external stimuli. There is evidence that weak EMFs, much lower than those at which a rise in temperature would occur, can also cause biological effects.

Currently, studies on the effects of non-ionizing high-frequency EMR are clearly focused on cancer risk, due to concerns about the carcinogenic properties of ionizing radiation.

Negative manifestations

Thus, the impact on a person of electromagnetic radiation, even non-ionizing, takes place, especially in the case of high-voltage power lines and the corona effect. Microwave radiation affects the nervous, cardiovascular, immune and reproductive systems, including causing damage to the nervous system, changing its response, electroencephalogram, blood-brain barrier, provoking a disturbance (wakefulness - sleep) by interfering with the work of the pineal gland and creating hormonal imbalance , changes in heart rate and blood pressure, impairing immunity to pathogens, causing weakness, malnutrition, growth problems, DNA damage, and cancer.

It is recommended to erect buildings away from EMP sources, and protection from electromagnetic radiation of high-voltage power lines should be mandatory. In cities, cables must be laid underground, as well as equipment that neutralizes the effect of EMP.

According to the results of a correlation analysis based on experimental data, it was concluded that it is possible to significantly reduce the impact of electromagnetic radiation of power lines on a person by reducing the distance of wire sag, which will lead to an increase in the distance between the conductive line and the measurement point. In addition, this distance is influenced by the terrain under the power transmission line.

Precautionary measures

Electricity is an integral part of life modern society. This means that EMP will always be around us. And in order for EMF to make our lives easier, not shorter, some precautions should be taken:

• Children should not be allowed to play near power lines, transformers, satellite transmitters or microwave sources.
• Locations where the density exceeds 1 mG should be avoided. It is necessary to measure the EMF level of devices in the switched off and operating state.
• It is necessary to carry out a rearrangement in the office or at home in such a way that it is not exposed to the field of electrical appliances and computers.
• Don't sit too close in front of the computer. Monitors vary greatly in the strength of their EMP. Do not stand near a working microwave oven.
• Move electrical appliances at least 2 m from the bed. Do not allow wiring under the bed. Remove dimmers and 3 position switches.
• Be careful when using wireless devices such as electric toothbrushes, shavers.
• In addition, it is recommended to wear as little jewelry as possible and take it off at night.
• It is also necessary to remember that EMP passes through walls, and to take into account sources in the next room or outside the walls of the room.

Each substance has a certain radiation. It arises due to the creation of an electromagnetic field around the material and its propagation in a certain direction. The farther charged particles move from their source, the stronger the electromagnetic field of the substance, and hence the stronger the electromagnetic radiation. In this case, the described radiation has the property of attenuation, that is, the farther 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, which are formed under the influence of electric and magnetic fields. From the point of view of scientists, a unit of radiation is a quantum, but it also has the properties of a wave (for example, it decays as the object of influence moves away).

Currently, the following types of electromagnetic radiation are distinguished:

• Radio frequency (propagated in the form of radio waves);
• Thermal or infrared rays;
• Optical waves that can be detected by the naked eye of a person (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 perturbed by special devices or equipment, usually man-made;
• Natural, when electromagnetic radiation comes from the elements of nature. So, all electromagnetic fields and radiations formed by the planet Earth, electrical processes occurring in the layers of the atmosphere, nuclear reactions on the Sun, are among the natural ones.

Radiation is also 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:

• power transmission lines (mainly high-voltage, transporting the main volume of electricity and creating a large EMF at the same time);
• electric transport (trolleybuses, trams, subways, powered by high strength current);
• towers necessary for the transmission of television and radio signals, as well as a mobile signal;
• 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, TVs and other devices equipped with an electron ray tube display;
• irons, refrigerators, air conditioners and so on;
• low-current networks that provide energy transfer from the source to various devices and equipment (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 single dose of radiation to the human body, but this is necessary for the diagnosis or treatment of certain diseases.

Human electromagnetic field

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

Attempts to measure the human electromagnetic field were made by scientists as early as the 18th century, but without the availability of appropriate equipment that would have the necessary level of sensitivity, this could not be done. All studies were limited only to the analysis of the effect of EMR on people.

A breakthrough in this issue 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, devices have appeared that make it possible to more accurately measure the influence of an electromagnetic field on a person and to record the self. human EMR and other living organisms. This gave impetus to the development of a new branch of science - biomagnetism, which investigated the EMF of animals and people, characterized by minimal values, as well as their influence on various natural processes.

The presence of its own electromagnetic field in humans harmonizes the work of all cells of the body. Some scientists call people's EMF a biofield or an aura. This area explore psychics. From their point of view, it is the biofield that is the main protection of the body from negative impacts external environment, including emotional. As soon as problems arise in the biofield, a person begins to get sick, he has various troubles, so he must be immediately restored, for which non-traditional methods are used.

The impact 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 exposure can lead to pathological changes in human organs. The most disappointing conclusion is that changes as a result of EMF exposure occur at the level genetic code, that is, the consequences may affect the children of the exposed.

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

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

The influence of electromagnetic waves on human health can be general or local. So, being close to a high-voltage power line, the entire body is irradiated, the effect of EMF occurs on all organs and all parts of the body. A mobile phone, on the other hand, affects only those parts of the body or the sense organs next to which it is located. Therefore, it is not recommended to talk on the phone for a long time in order to avoid a high dose of brain radiation.

In addition to electromagnetic effects, there is also a temperature effect of EMF on living organisms. Since EMR 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 that convert electrical energy into thermal, creating such temperatures that allow you to melt the metal and carry out other complex operations. However, this equipment has a significant side effect due to the high power of EMR and, accordingly, its effect on the tissues of human organs.

Important to remember! IN Everyday life people also experience EMP. This happens when using household appliances, mobile phones, moving in electric vehicles, and so on. EMR is not excreted from the body, it accumulates, which leads to diseases of the nervous system or brain. To avoid such a development of events, it is recommended to measure the electromagnetic radiation in the apartment and periodically monitor its magnitude.

Since EMR is of a wave nature, its effect on the 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 effect of EMR on the body, various methods protection. 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, therefore, household protection against EMP is based on the following recommendations:

1. You should be as far away as possible from the source of radiation. So, for a power transmission line, the safe distance is 25 meters, for a monitor with a ray tube - only 30 cm. Mobile phones are not recommended to be brought closer to the head than 2.5 cm. time of negotiations;
2. It is recommended to periodically measure the EMI level of used household appliances and control the time of their operation. 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 a computer or watching TV and tightly control it;
3. If the device is not in use, it must be turned off, because the switched on device continues to create EMF and spread radiation. It will also increase the safety of family members and make them healthier.

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