If there is a 220KV high voltage line on my house, I will be determined not to live.
220KV high voltage distance of 3 meters is safe. But the electromagnetic radiation that comes with it is seriously harmful.
The family has anemia patients, pregnant women are determined not to live in the high-voltage lines within 100 meters.
I am studying high voltage out. I went to the power station internship, in the power station work people are on 2 days off 2 days. Think about what you can get out of being under a high voltage line every day. Which houses with high voltage wires on their heads can only be used as offices, warehouses or whatever. Can not live in people!
(For your information. High-voltage wires more places. Plants grow particularly well, the reason I looked for. Because where plants don't grow bugs 。。。。。。。)
See below for information
Decree No. 18 of March 25, 1997 of the State Environmental Protection Administration - "Measures for the Management of Electromagnetic Radiation Environmental Protection," has explicitly included power transmission and substation systems of more than 100 kilovolts in the list of electromagnetic radiation construction projects and equipment.
There are currently three protection standards on electromagnetic radiation:
Standard for Protection against Electromagnetic Radiation (GB8702-1988) issued by the State Environmental Protection Administration (SEPA)
Hygienic Standard for Ambient Electromagnetic Waves (GB9175-88) issued by the State Ministry of Health (MOH)
The 500KV Ultra-High Voltage Transmission and Substation Project recommended by the State Environmental Protection Administration (SEPA) Technical Specification for Evaluation of Environmental Impact of Electromagnetic Radiation (JH/T24-1998).
The first two are national standards and the latter is an industry technical specification.
The Environmental Electromagnetic Wave Health Standard issued by the Ministry of Health of the People's Republic of China clearly states that "this standard is suitable for the environmental electromagnetic radiation in places where all populations regularly reside and move around".
State Environmental Protection Administration issued the "Electromagnetic Radiation Protection Standards" also explains: "Electromagnetic radiation referred to in this method refers to the energy flow in the form of electromagnetic waves propagated through space, and is limited to non-ionizing radiation, including electromagnetic wave emission in information transmission, industrial, scientific, medical applications of electromagnetic radiation, high-voltage power transmission and transformation of electromagnetic radiation generated in. "
Foreign countries have defined standards for transmission line safety
Shao Fang Yin, a famous electromagnetic expert of the Chinese Academy of Sciences, pointed out that whether the transmission line adjacent to residential industrial frequency magnetic field will have a harmful effect on the health of residents has become one of the hot spots of international concern. And industrial frequency magnetic field and electric field limit value has become the countries to define the transmission line is safe standard.
But at present, each country, on the neighboring houses of the industrial frequency magnetic field and electric field limit value, there is no completely unified standard. Some countries have developed their own standards, but the gap is not large.
Internationally, there are clear provisions on the limit value of the industrial frequency electric field adjacent to residential buildings in Poland, the Czech Republic, the United States of America, Montana ......
Some U.S. states do not specify the limit value of the field strength of the neighboring homes, but all the provisions of the line corridor edge of the field strength limit, the residential field strength will be much less than the edge of the line corridor field strength.
In 1995, the U.S. National Council on Radiation Protection (NCRP) proposed electromagnetic field exposure guidelines, which also mentioned Sweden based on living near high-voltage transmission lines, childhood leukemia and the correlation between the effects of the annual magnetic field level, the proposed industrial frequency magnetic field of 2 mG (0.2 μT) as a transmission line through the residential area of the guidelines.
Taking into account laboratory studies on ecological effects and epidemiological reports, the committee recommended:
1. That new nurseries, schools, and playgrounds not be built near magnetic fields exceeding 0.2μT.
2. That new houses not be built under or adjacent to existing high-voltage transmission lines, and that the time of exceeding the 0.2μT field not be more than 2 hours per day.
3. When new transmission and distribution lines are built, do not make the magnetic field exceed 0.2μT at the neighboring existing houses.
4. When new offices are built, reduce the intermittent and ambient magnetic field to 0.2μT.
USA: Lines should be reduced to reduce the exposure
First published in Sweden in 1979 by Wertheimer and Leeper, it is believed that the magnetic field is not the same as that of children living in other places. that children living adjacent to power lines had a higher chance of developing leukemia compared to children living elsewhere, which led to extensive research into whether industrial frequency magnetic fields could cause cancer. So far there has been no clear, definitive and consistent international conclusion on whether industrial-frequency magnetic fields are harmless to health.
On June 15, 1999, the U.S. National Institute of Environmental Health (NIEHS) submitted a report to the U.S. Congress on the "Health Effects of Exposure to Electric and Magnetic Fields in Power Lines". Among its conclusions and recommendations, "An international panel of 30 scientists voted (19/28 voting members) to conclude that 'limited reports have demonstrated an elevated incidence of childhood leukemia associated with residential exposures and chronic lymphocytic leukemia (CLL) associated with occupational exposures. '"
The report recommends that electric utilities follow existing practices to reduce exposure when choosing line paths and continue to explore new measures to reduce magnetic fields around transmission and distribution lines. The development of technologies that reduce magnetic fields on neighboring distribution lines is encouraged, provided they do not increase other hazards, such as accidental electrocution or fire.
