Netizen "Qingdao aided Dongguan Brother" reflected that every family in modern cities needs electricity, but no one wants to live under high-voltage lines. One is radiation, and the other is a safety hazard. Some communities have high-voltage lines next to them, and the owners have complained. The power supply bureau replied that the completion date of these communities was later than the planning and construction of high-voltage lines. Netizens believe that high-voltage lines should be buried to safeguard the interests of community owners.
Lei Liebo said: "Now, the whole face of Dongguan is changing, and the power supply department has done a lot of work, including the steady advancement of high-voltage lines into the ground.
He said that although the cost of high-voltage lines entering the ground is 10 times that of overhead high-voltage lines, the power supply department continues to steadily push forward the work of high-voltage lines entering the ground. Because the project involves a wide range, often involving planning, land and other departments, it is impossible to do it overnight, and it is necessary to combine the actual situation step by step.
The radiation of high-voltage lines is smaller than that of mobile phones, so don't panic.
As for the radiation of high-voltage lines, Lei Liebo said: "The radiation of overhead lines is measured by international standards. If you don't touch it, you won't enter the scope, and there is a reserved safety protection zone next to the high-voltage line. Electromagnetic radiation is much smaller than watching TV and using electricity. "
For example, he said that there are more than 6,000 people in Dongguan Power Supply Bureau. Many colleagues live and work on the line, and no one is unwell because of close contact with electricity. "The high-frequency penetration of mobile phones is very strong. The electromagnetic wave emitted by our power supply is 50hz, which has fast attenuation and poor penetration. It is electromagnetic induction, not radiation, and it is a completely different concept. " He said that citizens need not panic about this.

Introduction of radiation content
Radiation refers to the phenomenon that a part of electromagnetic energy from the field source propagates away from the field source and then returns to the field source. Energy propagates outward in the form of electromagnetic waves or particles (such as alpha particles and beta particles). All objects in nature always transfer heat in the form of electromagnetic waves and particles as long as the temperature is above absolute zero. This way of transmitting energy is called radiation. Radiation energy radiates linearly in all directions from a radiation source.
The energy released by an object through radiation is called radiant energy. Radiation is calculated in roentgen (r) per hour. An important feature of radiation is "equivalence". Objects (gases) radiate outward regardless of temperature. Object A can radiate to object B, and object B can also radiate to object A. This term is usually used for ionizing radiation. Radiation itself is a neutral word, but the radiation of some substances may bring harm.
