The most dangerous sources of electromagnetic radiation. What effect does electromagnetic radiation have on humans?

Electromagnetic radiation is the divergence of electric and magnetic fields. The propagation of the electromagnetic field occurs with the help of electromagnetic waves, which in turn emit charge particles, molecules, atoms and other components. Harm electromagnetic radiation has been officially proven and confirmed by relevant scientific research, therefore, as far as possible, its effect on the human body should be limited.

Education and use of electromagnetic radiation

Part natural factors includes magnetic and electromagnetic radiation that is generated by the core globe. Man-made types of radiation include high-frequency and ultra-frequency waves, as well as light rays and laser radiation. Human exposure to electromagnetic fields and radiation of both natural and anthropogenic origin tends to negative influence on almost all organs and systems, as well as the body as a whole.

How electromagnetic radiation affects humans, as well as what consequences it leads to, has been known for quite some time, but it is almost impossible to limit its use. This is due to the fact that this type of radiation underlies the activities of television and radio communications, since it is thanks to electromagnetic pulses that the visualization of the transmitted image from the television center to each television becomes possible.

This type radiation is also widespread in work mobile phones, since connections between subscribers occur using electromagnetic pulses. The impact of electromagnetic networks on the human body also occurs when using computer technology, Internet connections and much more.

The generated electromagnetic radiation is widely used in modern society, since thanks to its generation we have access to radio and telecommunications, mobile communications, computer technologies and much more.

The area of ​​contact with the field (which has a detrimental effect on humans), and the body’s ability to resist and resist are also taken into account. A circumstance that is worth paying attention to when determining such a phenomenon as electromagnetic radiation is the consequences of such influence.

The influence of electromagnetic radiation on the human body

The consequences of such impact depend on a number of external and internal factors, however, even its smallest influence disrupts homeostasis at the atomic-molecular level. With increasing intensity of influence, such changes can be expressed at the cellular, systemic or even organismal levels.

IN to the greatest extent The nervous system suffers, as well as the cardiovascular system. First there are signs such as headache and dizziness, general weakness, sleep disturbance, etc. Blood pressure suffers, changes also manifest themselves in an increase or decrease in blood pressure. This is followed by a slowing of the pulse, heart pain (may be accompanied by tachycardia or bradycardia), hair loss and brittle nail plates. In the early stages, damage caused by electromagnetic radiation is reversible. It is possible to get rid of such consequences by stopping exposure negative factor, as well as after symptomatic therapy.

If the influence of the electromagnetic field on the human body had a direct connection with a violation of the main and medulla oblongata, which are especially sensitive to such radiation, changes in the nervous system are considered irreversible and cannot be leveled. They can manifest themselves in impaired coordination of movement, rarely cause deviations in muscle tone such as a convulsive attack, etc.

In addition to the harmful biological effects on the body, which manifests itself nearby systemic violations, the influence of the electromagnetic field on a person also contributes to the formation of charges when the body comes into contact with a metal object.

This can occur when a person (who is not touching the ground) touches a metal object (which is in direct contact with the ground). It may cause unpleasant pain or even minor seizures.

If you notice symptoms from exposure to electromagnetic radiation, you should immediately seek specialized advice. medical care. Stopping the impact of a negative source and independent conduct drug therapy will improve the patient’s condition, but in any case you should consult a doctor.

Methods of protection against electromagnetic radiation

The main methods of protection are:

So, we have figured out how the electromagnetic field affects human health and what consequences the body’s interaction with radiation sources can lead to.

When answering the question of how to protect yourself from excess in an apartment, it is worth noting that compliance with all safety conditions and keeping contact with sources of this type of negative impact to a minimum will help reduce the risk of consequences.

ELECTROMAGNETIC RADIATION AND ELECTROMAGNETIC FIELDS - INVISIBLE KILLERS

We were taught at school that work turned a monkey into a man, and scientific and technical progress- the engine of all humanity. It would seem that with its movement the quality and number of years lived by a person should improve. In fact, the deeper STP enters our lives, the harder our lives are and the more often people encounter previously unknown diseases, which appear and develop in direct progression along with technical progress. Let us not dispute that the benefits of civilization are bad. Let's talk about hidden threat for humans and their descendants - electromagnetic radiation.

Research by scientists over the past decades shows that electromagnetic radiation is no less dangerous than atomic radiation. Electromagnetic smog, interacting with the electromagnetic field of the body, partially suppresses it, distorting the human body’s own field. This leads to a decrease in immunity, disruption of information and cellular metabolism inside the body, the occurrence of various diseases. It has been proven that even at a relatively weak level, prolonged exposure to electromagnetic radiation can cause cancer, memory loss, Alzheimer's and Parkinson's diseases, impotence, destruction of the lens of the eye, and a decrease in the number of red blood cells. Electromagnetic fields are especially dangerous for pregnant women and children. Electromagnetic radiation contributes to sexual dysfunction in men and reproductive dysfunction in women.

American and Swedish scientists established a safe limit for human health on the intensity of electromagnetic fields - (0.2 µT). For example, a washing machine - 1 μT, a microwave oven (at a distance of 30 cm) - 8 μT, a vacuum cleaner - 100 μT, and when a train departs for the subway - 50-100 μT.

Scientists have long been talking about negative impact on children's body electromagnetic fields (EMF). Since the size of a child’s head is smaller than that of an adult, the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in an adult. This applies to mobile phones, which simply expose the brain to “local” overheating. Experiments on animals confirmed that with increasing doses of high-frequency radiation, literally welded areas formed in their brains. Research by US scientists has proven that the signal from the phone penetrates the brain to a depth of 37.5 mm, which creates interference in the functioning of the nervous system.

Growing and developing tissues are most susceptible to the adverse effects of the electromagnetic field. It is also biologically active in relation to embryos. A pregnant woman working at a computer is exposed to almost the entire body, including developing fetus By the way, those who think that laptop computers are practically safe are mistaken. Think carefully about the negative consequences of their exposure before placing a laptop computer on your stomach or lap. Yes, LCD screens do not have electrostatic field and do not carry x-rays, but a cathode ray tube is not the only source of electromagnetic radiation. Fields can be generated by a supply voltage converter, control circuits and information generation on discrete liquid crystal screens, and other equipment elements.

SO HARMFUL OR NOT?

When talking about EMFs, we can’t help but mention Wi-Fi. On the Internet you can find many articles on this subject: “Wi-Fi networks are dangerous to health”, “Does Wi-Fi have a harmful effect on the human body?”, “Radiation from Wi-Fi networks harms trees, scientists say”, “Is it harmful Wi-Fi technology for children?

In the United States, there are examples of parents suing over Wi-Fi installed in schools and universities. Parents' fears that wireless networks cause irreparable harm to the health of children and adolescents, having a destructive effect on the growing body, are not unfounded. Wi-Fi, for example, operates at the same frequency as a microwave oven. For humans, this frequency is not at all as harmless as it seems. Behind Lately Some 20,000 studies have been published. They prove the fact that Wi-Fi negatively affects the health of mammals, in particular, human health. Migraines, colds, joint pain, but most often, diseases caused by Wi-Fi include cancer, heart failure, dementia and memory impairment. In the US, UK and Germany, Wi-Fi is increasingly being abandoned in schools, hospitals and universities. The reason for the refusal is said to be harm to human health. Today, there is no official verdict in the case of Wi-Fi, as there was with the WHO recognition of the harm of mobile phones. After all, the revealed truth will bring considerable losses to those who are not interested in it. As they say: “Saving a drowning man is the work of the drowning man himself.” And the reader is right who, after reading an article about the dangers of Wi-Fi, wrote: “In the end, everyone decides for themselves why they are sick.”

ELIMINATE THE NEGATIVE ELECTROMAGNETIC INFLUENCE OF WI-FI

The impact of Wi-Fi on the human body, unlike a mobile phone, is not so noticeable. But if you still use wireless technologies to connect to the Internet or corporate network on permanent basis- refuse them. Better have a regular one twisted pair. Try to reduce the time you use wireless networks of any kind. Do not keep the source of electromagnetic radiation close to your body. Minimize the amount of time you use your mobile phone or Bluetooth headset. Use a wired connection. If you are pregnant, try to stay as far away from wireless networks as possible. No one has yet proven the harm of exposure to Wi-Fi on pregnant women. But who knows how this know-how will affect the body of the unborn baby? After all real love for a child is not about buying another toy or beautiful clothes, but about raising a child strong and healthy.

IN medical center"Paracelsus" You can undergo impact diagnostics electromagnetic influences on your body. At the same time, the equipment allows you to differentiate the types of electromagnetic influences - man-made, geopathogenic, radioactive, determine the degree of electromagnetic load (4 degrees in total) and effectively neutralize this negative effect on the body.

Technological progress has reverse side. Global use various equipment, powered by electricity, caused pollution, which was given the name - electromagnetic noise. In this article we will look at 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, which arise when a magnetic or electric field is disturbed. Modern physics interprets this process within the framework of the theory of wave-particle duality. 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 spectrum of frequencies of electromagnetic field radiation allows us 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 radiation scale) can be seen in the figure below.

Nature of radiation sources

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

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

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

Concerning artificial sources, then 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 sources with high levels of EMR 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;
• voltage conversion installations electrical network(in particular, waves emanating from a transformer or distribution substation);
• elevators and other types of lifting equipment that use an electromechanical power plant.

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

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

It is worth highlighting special equipment used in medicine that emits hard radiation (X-ray machines, MRI, etc.).

Impact on humans

In the course of numerous studies, radiobiologists have come to a disappointing conclusion - long-term 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 cause disturbances at the genetic level.

Video: How electromagnetic radiation affects people.
https://www.youtube.com/watch?v=FYWgXyHW93Q

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 effect on human health of radiation, which is of an electromagnetic nature, directly depends on the location. It can be either local or general. In the latter case, large-scale exposure occurs, for example, radiation produced by power lines.

Accordingly, local irradiation refers to exposure to certain areas of the body. Coming from electronic watch or mobile phone electromagnetic waves, a vivid example of local influence.

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 vibration of molecules), this effect is the basis for the operation of industrial microwave emitters used for heating various substances. In contrast to its benefits in production processes, thermal effects on the human body can be detrimental. From a radiobiological point of view, being near “warm” electrical equipment is not recommended.

It is necessary to take 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. As electromagnetic noise increases, the number of characteristic diseases of the brain or nervous system increases. Note that radiobiology is a fairly young science, so 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, to reduce its effect, it is enough to move away from the source at a certain distance.

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

Radiation protection

In production, absorbing (protective) screens are actively used as 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 (the power of the source must be taken into account);
• for CRT monitors and TVs this distance is much smaller - about 30 cm;
• Electronic watches should not be placed close to the pillow, optimal distance for them 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 next to high-voltage power lines, but most people do not attach importance to ordinary household electrical appliances. Although it is enough to place the system unit on the floor or move it further 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 to clearly verify its reduction.

This advice also applies to the placement of the refrigerator; many people place it near the kitchen table, which is practical, but unsafe.

No table can indicate the exact safe distance from specific electrical equipment, since radiation may vary, both depending on the device model and the country of manufacture. IN currently There is no single international standard, so different countries standards may differ significantly.

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

Try to reduce the time you are exposed to radiation, that is, do not stay near operating electrical devices 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 notice that warm does not always mean safe.

Always turn off electrical appliances when not in use. People often leave various devices turned on, not taking into account that at this time electromagnetic radiation is emanating from electrical equipment. Turn off your laptop, printer or other equipment; there is no need to expose yourself to radiation again; remember your safety.

Electromagnetic radiation has become a planetary disaster for humanity. Radiation sources are found at every step, the maximum permissible dose is difficult to determine, it is different for each person. Electromagnetic chaos is raging both in production and in everyday life.

Each person has his own biofield, which is connected with the electromagnetic field of the Earth. Each human organ operates at a certain frequency. If any organ is exposed to a radiation source operating at a similar or multiple frequency, then it can either increase or “extinguish” the frequency that is considered acceptable for this organ. Strong and prolonged exposure to radiation on the organs of the human body leads to serious diseases.

Electromagnetic radiation negatively affects the entire human body, but the most severely affected are: the central nervous system, endocrine system, immunity, brain, and genitals. These radiations are especially dangerous for children, youth, and pregnant women. Negative impact can accumulate if the exposure lasts for a long time, so the painful consequences do not appear immediately, but seem to be pushed into the future. But then they reveal themselves in all their glory. Such consequences can be hormonal disorders, blood cancer, brain tumors and various painful changes in the central nervous system. Electromagnetic waves are also dangerous for people with disorders of the cardiovascular, nervous or hormonal systems, for elderly and weakened people. And all city dwellers during the winter and spring months can be classified as weakened people.

Life on Earth began under conditions of relatively weak electromagnetic radiation. Their sources were the Earth's magnetic field, cosmic and solar radiation. Today, the intensity of electromagnetic fields on our planet has increased by several orders of magnitude. The main pollutants: overhead power lines, radio communications, radar, television, radio navigation, industrial enterprises (moreover, certain production activities use low frequencies that are especially harmful to humans - up to 100 Hz). For example, within a radius of 1 km from the Ostankino TV tower there is such a powerful magnetic field that this place is harmful for living.

An ordinary power line (PTL) has an extremely harmful effect on human health within a radius of 20-30 meters, and a high-voltage line - within a radius of 50 meters. They should be located 200-300 meters from settlement. Ordinary trolleybuses and trams (on average) “magnetize” space by an amount 150 times greater than officially permissible rate. Only when a metro train departs does the electromagnetic field exceed the normal background hundreds of times. Similar examples from modern life There are many that can be cited.

Research on the influence of electromagnetic radiation on human body showed that people living or working near sources of strong radiation (radar installations, transformer substations, power lines, television stations), your health worsens, and the likelihood of cancer increases.

There are also many enemies in our homes, of which we are not even aware. First of all, this is a TV and a computer. Children and teenagers sometimes get strange headaches from constantly sitting in front of the TV or computer. There are no apparent reasons for this, the origin of the pain is unclear. There are other signs: dizziness, decreased memory and concentration, weakness, increased fatigue. Then there is a steady decline protective forces person. From computer games There is a surge in neuropsychic disorders, diseases of the eyes, and the skeletal system.

As for TV, everyone knows that it is better to watch it from a distance of no closer than 1.5 - 2 meters. Someone might argue that the electromagnetic radiation of a modern TV or display ends at a distance of 20-40 cm from the screen. Where does this harm to human health come from? The thing is that the electromagnetic field generates disturbances in torsion fields, which destroy the human biofield. For them, any type of physical matter is completely transparent, and no screens can save them. In addition, the impact of torsion disturbances can GRADUALLY ACCUMULATE. In addition, all these effects remain imperceptible to humans. We do not see or feel these fields, but their intangible influence distorts both the subtle field components of the surrounding space and the field shells of our body. A negative torsion field destroys a person’s biofield and vitality, which in turn negatively affects his health. Consequences of this phenomenon: syndrome chronic fatigue, “electronic disease”, cardiovascular diseases, infertility.

Other household appliances, such as lamps, are not at all harmless. It is better not to buy chandeliers in the form of a hemisphere facing down and hanging from the ceiling. This shape creates directional radiation. You can be in a room with such a lamp, but you cannot sit under it. The same applies to small hemispherical lamps - sconces: under no circumstances should they be mounted above the head near the bed. It is better to buy hemispherical lamps facing upward - the radiation should be directed towards the ceiling, not towards the floor.

It is dangerous to keep a trellis mirror in the bedroom. And if there is one, make sure that all the mirrors are in the same plane. Otherwise, a zone of strong radiation is created. In general, it is better to buy mirrors that are attached to the wall - it is harmless.

Architectural forms can also form in the house negative zones. A round room is best, but since this is rare now, we will focus on just one detail. Angles are the most dangerous places- drives negative energy. Therefore, we advise you not to push the sofa there and do not lie down with your head in the corner. You should also not sit near the corner of the table. This is not superstition at all, an angle in in this case acts as a dumping antenna and creates a directed flow of radiation. In this sense, round or oval tables and chairs are much better. General advice: rearrange the furniture in the apartment once a year to avoid the accumulation (stagnation) of negative energy.

Various electromagnetic therapeutic devices, in addition to their therapeutic effect, have contraindications and limitations. First of all, in terms of the time of interaction with them. Since they provide electromagnetic burden, other human systems and organs may suffer during the “therapeutic session,” primarily the cardiovascular, immune, central nervous systems and others. Therefore, constantly using or carrying active electromagnetic devices (generators, electronic tablets, etc.) is dangerous to human health. For example: a household “Chizhevsky Chandelier” of an open type, except positive action- ionization, air disinfection, has side effects - this is an electromagnetic and radiation burden on the human body. Radiation is what it is ionizing radiation. The Chizhevsky Chandelier is designed to ionize the air, but not people. Therefore, it cannot be turned on when there are people in the room. Simple safety and precautionary measures are to leave the room while the air is purified while the chandelier is on and working. Many professional medical services related to the use of electromagnetic and electronic devices, are always limited to a short treatment session. In this case, the doctors themselves, who service these devices throughout the working day, suffer more and more often.

Application of ANY electrical appliances leads to electromagnetic burden of the human body. Therefore, when using various household devices, you need to take simple precautions. When operating ANY electrical appliance, problems arise. electric fields and radiation that is dangerous to human health. For example, the use of electric kettles, and even those with an open spiral inside, has an extremely negative effect on the quality of water, and therefore on human health. But our industry has tried this: this is technology for the lazy - fast, convenient, beautiful and very harmful!

Negative consequences " technical progress"They hit the person directly. People are becoming more susceptible various diseases, biological security and vital activity decrease, new diseases appear, the most dangerous diseases develop, including cardiovascular, endocrine, immune, and oncological ones. Ultimately, there is a loss of human vitality, deterioration labor activity, reduced life expectancy, children's illnesses. The importance of the problem is evidenced by the corresponding resolution of the Security Council of the Russian Federation “On the danger of electromagnetic pollution.” The most active emitters of electromagnetic fields are well known - these are computers and office equipment, radiotelephones (including mobile or cellular), microwaves, TVs and VCRs. The list goes on and on. Even modern reinforced concrete walls “sound.” One must be wary of harmful radiation even from large quantity banknotes, which for a long time store the accumulated harmful energy of negative psycho-emotional states of a person (both the manufacturer, intermediate users, and the owner), enhancing the already off-scale harmful effect of other deviations.

The security situation, especially in big cities, is now extremely difficult. Therefore, wash your apartment with clean water more often, ventilate it, clean it with candle fire and prayer, use electrical appliances less and do not leave them plugged in. If you have small children (or grandchildren), then it is better to change your city apartment to a separate house - brick or wooden; It’s better to exchange a big city for a small town; and best of all - an urban lifestyle to a rural one.

ADVIСE

For an apartment: if possible, reduce the number of electrical appliances in your home, especially in the kitchen. It is advisable to place the refrigerator and microwave oven further than 2 meters from dining table. Move the TV away from the sofa and armchairs. The bed should be no closer than 3 meters from sources of continuous radiation, including the power cable. From external influences They protect the walls quite tolerably; as additional protection, you can glaze the windows with metallized glass covered with a screening film.

For activities: If you work in an office, your computer monitor needs a special protective filter. Place flowers near your computer that absorb negative radiation (for example, cacti).

For a summer residence: it is best if the nearest high-voltage power line is located at a distance of more than 300 meters from your site. A regular line can be lowered by 20-30 meters. If you are unlucky with this, it is better to plant ornamental crops on the site that require the least care and are not used for food.

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 throughout 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 high energy potential, which acts on atoms in cells and leads to their change natural state. It can be deadly as it causes cancer and other diseases. K not ionizing radiation include electromagnetic radiation in the form of radio waves, microwave radiation and electrical vibrations. Although it cannot change the structure of the atom, its impact can lead to irreversible consequences.

Invisible danger

Publications in scientific literature raised the issue of the adverse effects on individuals and society as a whole of non-ionizing EMF radiation emanating from power, electrical and wireless devices in the home, at work, in educational and public institutions. Despite numerous challenges in establishing conclusive scientific evidence of harm and gaps in understanding the precise mechanisms by which it occurs, epidemiological analysis increasingly suggests a significant potential for injury from non-ionizing radiation exposure. Protection against electromagnetic radiation is becoming increasingly important.

Because medical education does not emphasize environmental health, some physicians are not fully aware of the potential health problems associated with EMR and, as a result, non-ionizing radiation events may be misdiagnosed and treated ineffectively.

While the possibility of damage to tissues and cells associated with exposure to X-ray radiation is beyond doubt, the impact of electromagnetic radiation on living organisms, when it comes 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 of which has different physical properties. They can be measured and expressed using frequency or wavelength. Some waves have a high frequency, others have a medium frequency, and others have a low frequency. The range of electromagnetic radiation includes many different forms of energy coming from various sources. Their name is used to classify types of EMR.

The short wavelength of electromagnetic radiation, corresponding to high frequency, is a characteristic of gamma rays, x-rays and ultraviolet radiation. More spectrum includes 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, invisible and unnoticeable to humans. Their detection requires measuring electromagnetic radiation using special instruments, and, as a result, people cannot assess the extent of exposure to energy fields in these ranges.

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

Anthropogenic EMP

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

• lower scale of electromagnetic radiation from power lines, electrical appliances and electronic equipment;
• microwave and radio emissions from wireless communication devices such as Cell Phones, cell towers, antennas, as well as 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 frequency of electromagnetic radiation is in the range of 3-150 kHz (propagated and re-radiated by wiring).

Currents in the ground, which are sometimes called stray currents, are not limited by wires. The current moves along the path least resistance and can pass through any available paths, including ground, wires and various objects. Respectively, electrical voltage is also transmitted through the ground and through building structures via metal water or sewer pipes, resulting in non-ionizing radiation being released into the immediate environment.

EMR and human health

While studies examining the negative effects of electromagnetic radiation have sometimes produced conflicting results, findings of reproductive dysfunction and cancer susceptibility appear to support suspicions that EMF exposure may pose a threat to human health. Adverse pregnancy outcomes, including miscarriages, stillbirths, preterm births, altered sex ratios, and congenital anomalies have all been associated with maternal exposure to EMR.

A large prospective study published in the journal Epidemiology, for example, reported peak EMR exposure in 1,063 pregnant women in the San Francisco area. 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 EMR frequencies may be carcinogenic have been studied. For example, " International magazine cancer" recently published important research a case-control study on the association between childhood leukemia and magnetic fields in Japan. By assessing the level of electromagnetic radiation in bedrooms, scientists confirmed that high levels exposure leads to a significantly greater risk of 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 permanent psychological stress and fear of being affected by EMP. Many patients become incapacitated by the mere thought that an invisible wireless signal at any time and anywhere can provoke painful sensations in their body. Constant fear and preoccupation with health problems affect well-being up to the development of phobia and fear of electricity, which in some people makes them want to leave civilization.

Mobile phones and telecommunications

Cell phones transmit and receive signals using EMFs, which are 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 the possible adverse effects of their use on human health.

One of the problems in 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.

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

The relative depth of penetration in laboratory animals compared to the size of the human head is greater, and the tissue parameters and the mechanism of heat redistribution differ. Another potential source of inaccuracy in exposure levels is the effect of radiofrequency radiation on the cell.

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. Studies of radiation effects on technical staff started with the start of construction of the first 220 kV power lines, when cases of deteriorating health of workers appeared. The commissioning of 400 kV power lines led to the publication of numerous works in this area, which subsequently became the basis for the adoption of the first regulations limiting the effect of the 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 consists of endothelial cells associated with the zona septa, as well as adjacent pericytes and extracellular matrix. Helps maintain a highly stable extracellular environment necessary for accurate synaptic transmission and protects nerve tissue from damage. Increasing its low permeability to hydrophilic and charged molecules can be harmful to health.

Ambient temperatures that exceed the limits of mammalian thermoregulation increase the permeability of the blood-brain barrier to macromolecules. Neuronal uptake of albumin into various areas brain depends on its temperature and manifests itself when it increases by 1 ° C or higher. Since sufficiently strong radiofrequency fields can lead to tissue heating, it is logical to assume that the influence of electromagnetic radiation on humans results in 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 believing that they are being affected by EMR. This has led to speculation that electromagnetic fields may interfere with normal sleep patterns, with attendant health consequences. The potential risk of sleep disturbance must be considered in light of the fact 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, regular alternation of states of wakefulness and rest is a necessary requirement for ensuring proper operation brain, metabolic homeostasis and immune system.

Moreover, the dream appears to be exactly that physiological system, the study of which will make it possible to clarify the influence of electromagnetic radiation on humans high frequency, since in this biological condition the body reacts sensitively to external stimuli. There is evidence that weak EMFs, the intensity of which is well below that which would cause a rise in temperature, can also cause biological effects.

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

Negative manifestations

Thus, the influence of electromagnetic radiation on humans, even non-ionizing ones, occurs, especially in the case of high-voltage power lines and the corona effect. Microwave radiation affects the nervous, cardiovascular, immune and reproductive system, including causing damage to the nervous system, changing its response, electroencephalogram, blood-brain barrier, causing disruption (wakefulness - sleep) by interfering with the functioning of the pineal gland and creating hormonal imbalance, changes heart rate and blood pressure, impairing immunity to pathogens, causing weakness, wasting, growth problems, DNA damage and cancer.

It is recommended to construct buildings away from EMI sources, and protection from electromagnetic radiation of high-voltage power lines must be mandatory. In cities, cables must be laid underground, and equipment that neutralizes the effects of EMR must be used.

According to the results correlation analysis, based on experimental data, it was concluded that the influence of electromagnetic radiation from power lines on humans can be significantly reduced 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 also influenced by the terrain under the power 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 EMFs to make our lives easier, not shorter, we should take some precautions:

• Children should not be allowed to play near power lines, transformers, satellite transmitters, or microwave sources.
• Places where the density exceeds 1 mG should be avoided. It is necessary to measure the EMF level of devices in the off and operating state.
• It is necessary to rearrange the office or home in such a way as not to be exposed to the field of electrical appliances and computers.
• You should not sit too close in front of the computer. Monitors vary greatly in the strength of their EMR. Do not stand near a running microwave oven.
• Move electrical appliances at least 2 m from the bed. Wiring should not be allowed under the bed. Remove dimmers and 3-way switches.
• Precautions should be taken when using cordless devices such as electric toothbrushes and razors.
• It is also recommended to wear as little jewelry as possible and remove it at night.
• It is also necessary to remember that EMR passes through walls, and consider the sources in next room or behind the walls of the room.
