Live near power lines is dangerous

Articles about real estate | Live near power lines is dangerous The main danger posed by power lines - is electromagnetic field. Scientists rank as one of the most serious types of environmental pollution. "Electromagnetic Smog," relentlessly and, more importantly, invisible aims of modern man: the electromagnetic field in a variety of surround us almost anywhere, wherever we are.

Influence of electromagnetic radiation, when it comes to low, not exceeding the rate of dose is expressed primarily in violation of the central nervous system. This can manifest as headaches, sleep disorders, depression and fatigue.

At high, far from sanitary standards doses of electromagnetic radiation a person can be exposed to violations of the immune, endocrine and reproductive systems, as well as chronic (including how to involve researchers, and cancer) diseases.

Protect yourself from electromagnetic fields emanating from power lines, rather difficult, especially if you live in close proximity to them ... sadly have to admit that even today we have anywhere in the metropolitan area can be found "spontaneous settlements" close to them, or even under these lines! Many manage to (primarily because of the cheap housing ...) to build there plots with small ogorodikami, apparently unaware of the dangers of this neighborhood. Even in urban areas often found houses built next to these lines: some of today's developers are not much in terms of environmental and social consciousness of the other Soviet officials. Therefore, the best way to protect in this case - just do not live in close proximity to power lines. So, if your home for whatever reason, is located in an unsafe proximity to these lines (sanitary norms secure location, see below), the best possible solution would be moving to a safer area.

Still, protection is possible. For these purposes, subject to special protective shields made of materials that prevent the spread of electromagnetic fields. Of course, screening is costly, and companies involved in installing them, very little in our market, but they do exist, one has only to look. For example, the installation of these screens are engaged in some of the companies providing environmental expertise.

At a typical urban development such screens, of course, do not exist, so not even worth asking about the possibility of their presence in the local Desaix. They need to establish yourself.

"Forewarned - hence protected", so the best that can be advised in this case - is, as always, the preventive measures.

And this is especially observance of sanitary-protective standards in the construction of housing that offer the best for the relative safety of the distance of residential facilities by power lines, depending on the voltage of each power line.

Thus, according to SanPiN № 2971-84, when the voltage is 330 kV transmission line, this distance (the length of the sanitary protection zone) should be equal to 20 meters and at a voltage of 500 kV safe distance equal to 30 meters, at 750 kV - 40 m, and at 1150 - 55 am

For densely built cities, where also distributed through less stress, have their own rules distance of dwellings from the power lines.

For example, for Moscow, these rules are as follows: when the line voltage below 20 kV, the sanitary protection zone should be 10 meters, at a voltage of 35 kV - 15 meters at 110 kV - 20 meters, at a voltage of 120 to 220 kV - 25 m from 300 to 500 kV - 30 meters, then the length of the sanitary zone coincides with the general rule (at 750 kV - 40 m, and at 1150 - 55 m).

And this raises another question: how do you determine the voltage of each particular transmission line? It can be calculated by the number of wires or the number of insulators in the chain, depending on the voltage line.

Thus, if the transmission line consists of only one wire, the voltage is less than 330 kW. If running two, the voltage of 330 kV. Three - 500 kV, four - 750 kV. Line, containing from 6 to 8 wires, has a voltage 1150 kV.

Voltage low-power transmission lines can be determined by the number of insulators in the chain: 15 pcs. - 220 kV, 6-8 pc. - 110 kV, 3-5 pc. - 35 kV, 1 pc. - 10 kV.
