China has officially entered the "5G era" and the construction of 5G base stations is in full swing everywhere, including Liaoning.On April 28, the provincial industrial Internet digital economy 5G network data center construction work promotion meeting was held, and it was proposed to vigorously promote the construction of a new basic society. This year, our province will invest more than 11 billion yuan to build more than 20,000 5G base stations with a network covering 14 cities in the province.Some people think that the 5G network has a high speed and the 5G base station transmitting signals must have relatively large radiation, which will cause harm to human health. Therefore, "building a base station is no problem, but it cannot be near my home" has become the subconscious idea of many people, also known as the "NIMBY effect".What is the truth? Is it really necessary to turn pale at the mention of building a base station?On April 29, the reporter talked with Xiong Yingyu, deputy director of the administrative examination and approval department of the provincial department of ecological environment, Yang Feifei, staff member of the nuclear and radiation safety management department of the provincial department of ecological environment, and Cui Chengguo, general manager of the operation and maintenance department of Liaoning branch of China Tower, to talk about 5G base station.-Does ——5G Base Station Have Radiation? Yes, but only electromagnetic radiation.Radiation is divided into ionizing radiation and electromagnetic radiation.Ionizing radiation is radiation produced by radioactive substances that can ionize the affected substances. Such as radioactive elements, nuclear reactors, nuclear weapons and other high-energy radiation mainly release ionizing radiation. The ionizing radiation dose is too high, which is harmful to human health."Electromagnetic radiation is different from ionizing radiation, and its health effect on human body is mainly thermal effect." Yang Feifei said that electromagnetic radiation is different from ionizing radiation in terms of formation mechanism, protection requirements and environmental standards. The type of radiation involved in a communication base station is electromagnetic radiation.-The base station is built downstairs in my house. Does it have a big impact on me? It has less influence than using an electric hair dryer.The radiation coverage area of the communication base station antenna is relatively wide. After a certain safe distance, the radiation value is very small. Moreover, walls, floors and other obstacles can also play a strong blocking role, so the impact on the human body is very small. As long as the limit requirements are met, public health and safety can be ensured, and there is no need to worry at all.Modern people are exposed to various electromagnetic radiation environments every day. Microwave ovens, televisions, etc. will generate electromagnetic radiation. The influence of communication base station on human body is smaller than that of daily use of hair dryer and induction cooker.The current electromagnetic comprehensive electric field strength of communication base stations in our country is implemented in the standard of "Electromagnetic Environment Control Limits" (GB8702—2014), and the control limit is 40 microwatts/cm2, which is stricter than the international general standard. Judging from the monitoring data, the electromagnetic radiation level of the existing communication base stations in our province does not exceed 2 microwatts/cm2. The electromagnetic radiation environment in our province is safe.
