Building under high-voltage lines is prohibited, and there are regulations related to planning and protection of power facilities
The wires on the roofs of these residential buildings are 110,000-volt high-voltage wires, which produce strong radiation that is harmful to the human body. In addition, because the voltage is as high as 110,000 volts, and the wire equipment may fail, so the building of high-voltage wires "harmful" and "harmless" sources
Foreign experts from the point of view of epidemiological investigations to conclude that
Foreign experts from the point of view of epidemiological surveys to the conclusion that "harmful";
domestic experts from the point of view of electricity to the conclusion that "harmless".
2. Who is most affected by high-voltage lines
The impact on children and teenagers is large, and the impact on adults is small.
3. How big is the impact of high-voltage lines?
British epidemiological investigators concluded that children living under electromagnetic radiation have a leukemia incidence rate of one in 700, double the incidence of children living without electromagnetic radiation (one in 1400).
Sweden's National Council for Industrial and Technological Development concludes: 1, children under 15 years of age who are exposed to an average magnetic induction intensity greater than 0.2 microtesla suffer from leukemia more than 2.7 times that of the average child; 2, if the magnetic induction is greater than 0.3 microtesla is 3.8 times.
Conclusion of the California Health Sciences Evaluation Institute: "Electromagnetic fields can lead to some degree to an increase in the risk of developing childhood leukemia, adult malignant brain tumors, amyotrophic lateral sclerosis, miscarriages, etc., and may cause suicide and adult leukemia."
4. How do high-voltage lines affect people? What is their safety index value?
High voltage lines carry high currents in them, and the magnetic fields generated by the high currents have an effect on human health.
British experts believe that the safety value of the magnetic field generated by high-voltage lines is 0.4 microtesla (μt), above which children will be at risk of disease.
5. What is the safe distance for high voltage lines?
High-voltage lines of 220 kilovolts (kV) have an electromagnetic radiation intensity of more than 0.4 microtesla (μt) within a hundred meters;
High-voltage lines of 132 kilovolts (kV) have an electromagnetic radiation intensity of more than 0.4 microtesla (μt) within tens of meters;
High-voltage lines of 11-66 kV have an electromagnetic radiation intensity of more than 0.4 microtesla (μt) within a few tens of meters;
Buried underground high-voltage lines have an electromagnetic radiation intensity exceeding 0.4 microtesla within only a few meters.
6, China's high-voltage line construction standards are far from being able to meet the safety requirements
China's standards stipulate that the magnetic induction intensity of less than 100 microtesla meets the high-voltage line construction standards.
7, high-voltage lines on the impact of real estate has appeared
Homeowners found that the impact of high-voltage lines on real estate has begun, 1, high-voltage lines near the housing rental prices fell; 2, high-voltage lines next to the purchase and sale of second-hand houses are also affected by the high-voltage lines, high-voltage lines so that hard work to fight a lifetime in exchange for a house is facing a depreciation of the value of the house;
