High voltage lines are a danger. High voltage power line next to the house

In the era of industrialization, it has long been proven and it is extremely unfavorable if a person long time is under the influence of electricity magnetic field coming from high voltage lines power transmission lines (hereinafter referred to as power lines), not to mention the constant stay in this field (place of residence, work, etc.). With a constant stay in such a field, the influence of power lines on human health becomes dangerous.

According to researchers of this problem, in places of residence near high-voltage power lines, the likelihood of children getting cancer is increased. People constantly exposed to electromagnetic fields of high-voltage power lines or serving power lines that do not comply with safety regulations are at risk of leukemia and brain cancer.

Long-term stay in the locations of electromagnetic fields can cause weakness, anxiety, irritability. The negative impact of power lines on human health is manifested primarily in disorders of the nervous system of the body - memory problems may appear, dizziness may occur. Often there are depressive states, and people complain of constant headaches, muscle pain.

The influence of power lines is dangerous for the health of pregnant women, as it can lead to miscarriages and the birth of children with abnormalities is possible, because human reproductive health suffers greatly from power lines. Impotence can develop in men, infertility in women, and “neighborhood” with power lines can lead to a decrease in sexual desire.
Another effect of power lines on human health is manifested in the impact on the cardiovascular system, immune system, endocrine system of the body, and vision problems arise.

Many do not know about the impact of power lines on human health and from this ignorance they buy country or garden plots in the areas of their location, where there are high voltage electric fields, and then the whole family "rest" all summer in these "fields". Also, many construction companies and organizations, taking advantage of people's ignorance of the impact of power lines on human health, are laying the foundation for the construction of residential villages in the locations of high-voltage power lines. Most likely, they themselves do not know about it, but there should probably be some organizations that are obliged to inform such builders that living in such places is not only harmful, but also dangerous to health.

Many people buy land themselves and build cottages under high-voltage power lines. But experts do not even advise walking under these lines, especially for children. And the one who builds a house for himself is going to live there ... What is it - elementary ignorance or a disregard for their health and the health of their loved ones? Even workers servicing power lines, with voltage electric field 15 kV / m, for safety reasons it is forbidden to work more than 1.5 (one and a half) hours a day!

The impact of power lines on human health is unambiguously devastating. Experts strongly recommend not to visit places where high-voltage lines are stretched unnecessarily, and it is strictly forbidden to spend the night there. This applies to hikers. Choose places to stay away from power lines. And a warning to gardeners - do not build any metal structures in the area where power lines are located - sheds, change houses, etc. Contact with such a metal object may result in severe electric shock.

I will be grateful for your opinion

In the 60s, specialists in Russia paid attention to the electromagnetic fields of power lines (TL). After lengthy and in-depth studies on the health of people who have contact with power lines at work, the results of these studies showed that people who were in the electromagnetic field for a long time often complained of weakness, irritability, fatigue, memory loss and sleep disturbance.

Currently, there are many problems associated with prolonged exposure to power lines on the nervous system, cardiovascular, immune and reproductive systems.

Power line(power line) - one of the components electrical network, a system of power equipment designed to transmit electricity through electric current.

The wires of a working power line create electric and magnetic fields of industrial frequency in the adjacent space. The distance to which these fields propagate from the wires of the line reaches tens of meters.

Within the sanitary protection zone of power lines it is prohibited:

place residential and public buildings and structures;

arrange areas for parking and stopping all types of transport;

to locate car service enterprises and warehouses for oil and oil products;

carry out operations with fuel, repair machines and mechanisms.

SanPiN №2971-84

And now what is happening in reality:

One of the strongest stimulants electromagnetic waves- industrial frequency currents (50 Hz). So, the electric field strength directly under the power line can reach several thousand volts per meter soil, although due to the property of reducing the tension by the soil, already at a distance of 100 m from the line, the tension drops sharply to several tens of volts per meter.

Studies of the biological effects of the electric field found that already at a tension of 1 kV / m, it has an adverse effect on the human nervous system, which in turn leads to disorders of the endocrine apparatus and metabolism in the body (copper, zinc, iron and cobalt), violates physiological functions: heart rate, blood pressure level, brain activity, stroke metabolic processes and immune activity.

As for electricians and other power line workers, the situation is even worse.

The power transmission line personnel had visual impairments, changes in color perception, narrowing of visual fields in green, red, and especially blue color, vascular changes in the retina. Studies have been conducted of professionals working 8 hours a day in contact with AMY. Some have experienced a decrease in sex drive, a tendency to depression and irritability. There was a decrease in the number of lymphocytes in the blood.

See what happens to the biofield of a person living near power lines:

Human biofield- this is its electromagnetic field, that is, the totality of the radiation of each cell of our body. In fact, it is possessed by any object on Earth, any living organism.

Our electromagnetic field was formed under the influence of the Earth's electromagnetic field. And since today's electromagnetic background is tens of thousands of times higher than natural, our field cannot withstand such an onslaught.

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.

From an energetic point of view, the biofield performs a protective function. It is also called an aura. In fact, this is the first protective barrier.

Facts:

One of the largest studies of this issue took place in England and Wales from 1962 to 1995.

Were considered medical records more than 29 thousand children under 15 years old

It turned out that the risk of leukemia in children who lived from birth at a distance of up to 200 meters from power lines is 70%, and from 200 to 600 m - 20%.

Statistical data showed that power lines have a significant Negative influence.

“Our study shows that about 5 out of 400 cases of childhood leukemia can be associated with high-voltage lines, which is about 1% of cases,” said Gerald Draper, head of the research team at the University of Oxford.

The works of V. N. Anisimov cite the facts of Swedish scientists:

They analyzed data on the incidence of cancer among people living in close proximity to high-voltage power lines (at a distance less than 300 m).

In a group of 400 thousand. person was found 142 children with various types malignant neoplasms and 548 adults with a brain tumor or leukemia.

Also, a survey was conducted on the subject of reproductive function in 542 workers substations power lines. This analysis revealed such pathologies as:
1) an increase in the number of congenital malformations if the father worked at a power plant;
2) decrease in the function of fertilization among a part of male workers
3) the birth rate of boys has decreased.

Was also examined youth group under 18 living and within 150 m from substations, transformers, metro, power lines railways and power lines. They were twice as likely to have disorders nervous system and leukemia.

In Denmark, 1707 children under the age of 16 were examined during the period. Due to living near power lines, some have developed brain tumors, leukemia.

Protection against electromagnetic fields of power lines:

And what to do??

We understand that if a power line is built near your house, you cannot move it. And not everyone can afford to move today.

And even if you don’t live near power lines, then, believe me, they make a very good contribution to the general electromagnetic background of the city in which you live anyway.

already exists today reliable protection from electromagnetic fields and their torsion components.

This must be done because the situation concerns your health and the health of your entire family. Especially if you are young and just planning it, or you have small children.

The existence of waves invisible to the eye in the Earth's atmosphere has long been known to mankind. There are two ways of their occurrence - natural and anthropogenic. In the first case, electromagnetic waves appear due to magnetic storms, and in the second - as a result of human activity. A prime example An anthropogenic source of such waves can serve as power lines - high-voltage power lines on reinforced concrete pillars (here ) is a convenient and relatively easy to implement method of transmitting electricity over long distances.But is this method as harmless as it is represented by power engineers?Let's try to figure it out.

Is it harmful to live near power lines?

Research in the field of the influence of electromagnetic fields on the human body has not stopped for several decades. It is still unknown to what extent the use electrical energy beneficial from an environmental point of view. More precisely, it was possible to prove the safety of household electricity for people and animals, but with industrial power networks everything is more complicated. Industrial frequency currents (50 Hz) are one of the strongest sources of electromagnetic oscillations.

According to Western scientists, living in close proximity to power lines can lead to health problems in the future, and this is largely due to the magnetic field. The researchers found that the conditionally safe threshold for magnetic flux density is 0.1 microtesla. Because of this, people living near power lines may experience discomfort when touching grounded objects - external walls buildings, outdoor furniture etc. Recently it became known that in order to prevent the harmful effects caused by the magnetic field, it is necessary to be at a distance of about 800 meters from the high voltage line. This means that the optimal and safe distance from residential buildings to power lines should be at least 1 km.

Verdict still pending

However, there are some factors that complicate the final decision. So, for example, in 2012, scientists found that the individual reaction to the electromagnetic field in people living in the same area varies greatly. This means that the body's sensitivity to external influences is due not only to age and type of activity, but also to a number of other reasons that specialists have yet to work on.

Conclusion

So, it is too early to make unambiguous statements for or against life near power lines - researchers still have too little information about the nature of electricity and its effect on the body. However, something is already known: when choosing housing, you should be guided by its location relative to the power grid and choose options located at a distance of more than 1 km from them.

Russians can contemplate power lines everywhere. At the same time, the spectacle is so familiar that few people attach special importance to it. This happens because a person is confident in the safety and reliability of the designated structures. However, in terms of safety, there are several points that can dispel all positive ideas about power lines. In this article, the reader will be told about negative impact electromagnetic field on the human condition.

Since the 60s of the last century, the opinion has taken root among scientists that the impact of power lines on living organisms negative character. So, according to observations, a person who is in close proximity to power lines for a long time becomes irritable and feels unwell.

In accordance with the conclusions made in the course of the studies, the rules for the operation of power transmission lines were adjusted. The changes were aimed at establishing prohibitions within the sanitary zone, including:

• construction of residential buildings, as well as structures in which people have to stay for a long time;
• organization of parking lots;
• handling flammable substances.

Unfortunately, not all rules in our country are followed, which leads to sad consequences.

Despite the fact that research on this issue is ongoing, to date, the following has already been established:

• Insects. Bees that have fallen under the influence of an electromagnetic field begin to behave chaotically and aggressively. In addition, there is a decrease in the activity of insects and their mortality. Other insects, in turn, falling under the influence of power lines, try to leave this area faster.
• Plants. As for plants growing in the zone of power lines, it is worth noting their susceptibility to severe deformations. So, the organs of representatives of the flora growing in the designated places have uncharacteristic sizes and shapes.

Impact on a person

As already noted, power lines cause ailments in a person. Thus, the main problems that people may encounter due to their long pastime under the influence of an electromagnetic field are:

• diseases associated with the work of the cardiovascular system;
• decrease in reproductive function;
• severe fatigue;
• bad memory;
• irritability;
• insomnia.

Thus, power lines have a strong negative impact on human health and mental state. That is why, it is worth listening to scientists and avoiding a long stay in the zone of the electromagnetic field of power lines.

When choosing real estate, we weigh many factors - the quality of access roads, distance from the city center, the development of communications, etc. But when communications in the form of high-voltage power lines (power lines) are directly above our heads, the question arises of how safe it is. And often selling housing near power lines is a big problem.

In the USSR, the magnetic component of the radiation of high-voltage power lines was not taken into account at all in safety standards. It was allowed both construction in the power transmission line zone and accommodation. The levels of magnetic radiation allowed in Russia since 2007 are now dozens of times higher than similar standards in Scandinavia and a number of other European countries.

Most of the experts interviewed by BN advise weighing and even taking some measurements before buying or building new housing near power lines.

A look into history

Oddly enough, humanity is much more aware of the safe levels of radiation than the critical levels of electromagnetic radiation. High-voltage power lines are precisely the sources of the electromagnetic field of industrial frequency - 50 Hz. Their wires are a kind of antenna for radio waves of enormous length - 6 million m, these waves are called "megameter". For comparison: FM radio stations broadcast on waves a few meters long, and GSM cellular networks use decimeter waves.

IN USSR allowable standards only the electric component of the field was taken into account, and the effect on human body the magnetic component was not evaluated at all.

There are no problems with the electrical intensity of the electric field. Maximum allowable level tension inside residential premises - 0.5 kilovolt per meter (kV / m), in residential areas - 1.0 kV / m. Exceeding it, according to experts, is very difficult, therefore, in the "Soviet" version, it was allowed to be under lines up to 220 kV as much as you like, and sometimes even to be built. Dacha settlements under high-voltage lines were quite common. Later, the so-called protection zones of power lines appeared, designed to protect the structures themselves rather than the health of the population. One way or another, they took into account the distance from the house to the power line.

Magnetism is worse than electricity

“Most of our practical studies confirm that the electric field strength near power lines does not exceed the established standards. According to the magnetic field - everything is not so simple. The magnitude of the magnetic field depends on the currents passing through the wires, the material of the walls of the building, and even the design of the power transmission line poles,” said the director of the Center electromagnetic safety, member of the Scientific Advisory Committee of the World Health Organization (WHO) EMF and Health Program Oleg Grigoriev. A number of Western studies show that living near power lines increases the risk of a number of diseases, and it is precisely because of the magnetic component. Some of the results are alarming.

Thus, Swedish scientists have found that people living at a distance of up to 800 m from power lines with a voltage of 200 kV are statistically more likely to have leukemia, brain tumors, and breast cancer. In men, the reproductive function decreases, the percentage of births of boys decreases. The researchers found that the fault of all these problems is the increased level of the magnetic component of the electromagnetic field, and estimated the dangerous threshold of the magnetic flux density at 0.1 microtesla (µT).

Finnish experts came to a similar conclusion. True, they conducted research in a five-hundred-meter corridor from power lines with a voltage of 110-400 kV. Finnish scientists considered the magnetic flux density value of 0.2 μT to be a dangerous threshold.

Edge of Risk

The WHO Cancer Research Agency has classified a power frequency magnetic field (MFMF) with a flux density above 0.3-0.4 µT as a group 2B "possible carcinogen". To make it clear, there is also group 2A (“probable carcinogens”) and group 1, which, in fact, includes absolutely proven carcinogens. WHO experts admit that the magnetic component of an industrial purity electromagnetic field with a flux density above 0.3-0.4 μT - "under conditions of prolonged chronic exposure, may be a carcinogenic environmental factor."

In fairness, we note that in the new millennium and Russian standards also "saw" at last the danger of the magnetic component of the field. SanPiN 2.1.2 1002-00 set the limit value of the magnetic index for residential premises at 10 μT, and for residential areas - at 50 μT. On November 10, 2007, more stringent limits came into force, amounting to 5 and 10 µT, respectively. Alas, even these figures are dozens of times higher than the "Scandinavian" threshold of 0.2 μT, which has become the official criterion for many states.

“A number of countries have confirmed these standards by law. These are Switzerland, Scandinavian countries, Israel and some others. But Russia is not on this list. I consider it expedient for newly commissioned residential facilities and for all school and preschool institutions follow the WHO recommendation on this issue. Although this does not have a hygienic justification, the WHO precautionary principle is just provided for such situations,” says Oleg Grigoriev.

While the representatives scientific world cannot find a biological justification for the effects of IPHR on the human body. There is also a dissenting opinion. Say, power lines cannot have a significant impact on human health, since at distances of 200 meters from the wires, the magnetic field formed by them is less than the Earth's magnetic field, which is 30-50 μT. However, we should not forget that the magnetic field of our planet is relatively constant, and does not vibrate at a frequency of 50 Hz per second, like MUF.

Enemies external and internal

When inspecting a property, you should not immediately panic if a power line is found nearby. First, evaluate its tension. In Russia, the most common power lines are 6, 10, 35, 110, 150, 220, 330 and 500 kV. You can indirectly determine what voltage a given line has by counting the number of insulators (in power lines up to 220 kV), or the number of wires in one bundle (“bundle”) for lines from 330 kV and above.

In areas of individual housing construction 6-10 kV lines pass through the streets, less often 35 kV. You have to deal with it (if potential buyer even such power lines are frightening, you should think about moving to a non-electrified ecovillage). Power lines from 110 to 750 kV pose a more serious danger.

“And the point is not even in the electromagnetic field, or rather, not only in it. Power transmission lines are a source of increased danger: hurricanes, wire breaks, lightning strikes into power transmission poles - all this, alas, cannot be ruled out, ”the chief occupational health specialist from Federal Service for Supervision in the Sphere of Consumer Rights Protection in the Novosibirsk Region Sergey Urzhumov.

If there is a choice, building under power lines is, of course, undesirable. Theoretically, a residential building located near power lines can be protected. A grounded roof made of corrugated board or metal tiles is well protected from the electric field, reinforcing mesh inside walls (which is why reinforced concrete walls attenuate radio waves best). But the roof and grid must be securely grounded. To suppress magnetic fields of industrial frequency, shielding with ferromagnets or multilayer "pies" of special steel grades may be additionally required.

But even if all this is organized and protected from external danger, you should not forget that you will be supplied with electromagnetic fields of industrial frequency in abundance by a refrigerator, iron, and even a cozy home floor lamp. Look at the table below and you will understand - in addition to external electromagnetic "enemies" in the house, there are many potentially dangerous internal sources.

Propagation of the magnetic field of industrial frequency from household electrical appliances(above 0.2 µT)

Power lines go underground

If Russia, following the developed countries, recognizes dangerous level IPHR of at least 0.4 μT, this will seriously affect the real estate market, since a significant number of individual and apartment buildings, kindergartens and schools will be in the zone advanced level IPHR. The authorities will have to organize expensive work to achieve a decrease in the level of the magnetic field. Perhaps the question will be about the transfer of one or another power line. However, in major cities, in particular in Moscow and St. Petersburg, programs have been developed to transfer power lines from the surface to the ground. This is largely done in order to free up expensive land plots currently under power lines for development. At the same time, the thickness of the earth can become a natural barrier to the propagation of electromagnetic waves, and it will become easier to achieve a safe level of radiation.

However, experts point to the danger of low-quality installation of underground lines, since the cost of the transfer is estimated at 1 million euros per 1 km, and developers will be tempted to save on safety. After all, if an overhead power line is always available for monitoring by operating and controlling organizations, then the dungeon, as you know, is a dark matter.

But overhead lines can be made safer. “Today, there are projects of supports, when due to the suspension of wires, phase splitting, etc., the field is vector-compensated,” says Oleg Grigoriev.

draw conclusions

Buy or build new house, according to most experts, it is still better to stay away from power lines. And not only because of the possible impact of IPHR. a huge role the “psi-factor” can also play, when the real danger will be much less than the phobias of the residents.

“Let me give you a funny story. Owners country house noticed that after the construction of a base station of a mobile operator nearby, bees disappeared on the site, and the number of flies and wasps sharply decreased. When checking, it turned out that the station had not yet been connected at all. So many appeals are due to purely psychological reasons - suspiciousness and fears, ”Sergey Urzhumov notes.

If a house or apartment is located near a power line and a potential buyer has doubts, you can call Rospotrebnadzor specialists and determine the levels of electric and magnetic fields. But since the level of the magnetic component depends on the amount of current in the wires, it is necessary to find out in advance from the energy company in what mode the power transmission line is operating at the time of diagnosis.
