In recent two years, the electromagnetic radiation of mobile phone base stations has become a hot topic. Some speculations, doubts, worries and fears without scientific basis are spreading quietly. Some citizens blindly believe in the exaggerated propaganda that electromagnetic radiation is harmful to health, and reflexes at the sight of the antenna of the base station, and blame health problems such as "physical discomfort", "poor sleep" and "increased hair loss" on the electromagnetic radiation of the base station. Some citizens often complain and strongly demand demolition.
Set up base stations and resolutely prevent new base stations. This situation increases people's anxiety and panic, which not only affects the mobile operation business, but also intensifies the contradiction between mobile operation units and citizen users.
Then, will the electromagnetic radiation of mobile base stations do harm to human health?
The answer is no, there is no scientific and factual basis for the statement that electromagnetic radiation from mobile base stations is harmful to human health, and the concerns of some citizens are completely unnecessary.
At present, there are 6307 mobile communication network stations (including base stations, repeaters and indoor distribution systems) in our city. In order to ensure the smooth mobile communication of users, mobile operators must set up base stations in appropriate locations according to the requirements of signal coverage quality, system capacity and electromagnetic compatibility of mobile base stations. At the same time, mobile operating units must apply to the municipal radio management department for setting up mobile base stations in accordance with regulations, and can only be set up and used after the radio management office has audited and tested to ensure that the technical indicators of the base stations meet the national technical indicators and safety and health standards. The mobile base station equipment is imported or produced after the model is approved by the Radio Management Office of the Ministry of Information Industry, and the work efficiency and standards are in line with the specifications.
In recent two years, according to the on-site monitoring and tracking monitoring of mobile base stations complained by the Municipal Management Office, the maximum electromagnetic radiation intensity is 0.2-0.8 ц w/cm2, which is far from the "first-class standard" stipulated in the national environmental electromagnetic wave health standard GB9 175-88 (Note: "first-class standard" refers to all people who live, work and live for a long time (. The allowable field strength of 10ц w/cm2 has a large margin, which fully meets the national health and safety standards. Therefore, it can be said with certainty that as long as the mobile base station is established with the approval of the municipal administrative office and its electromagnetic radiation intensity is strictly controlled within the safety standards, it is legal and safe and will not cause harm to human health.
Electromagnetic radiation sources are divided into natural radiation and man-made radiation, and lightning and sunspot activities will produce electromagnetic radiation, which is a natural phenomenon; Man-made electromagnetic radiation mainly comes from radio communication equipment and industrial and medical equipment, such as paging transmitters, hand-held mobile phones, helium arc welding machines, AC high-voltage transmission lines, automobile igniters, fluorescent lamps, microwave ovens, motors, televisions, computers and other equipment, which all have different degrees of electromagnetic radiation when working. On the earth, no matter when and where, there are all kinds of electromagnetic radiation with different wavelengths and intensities, which are invisible, intangible and inaudible.
Not all electromagnetic radiation will do harm to human body. Because the influence of electromagnetic radiation on human body is related to radiation intensity, frequency, action time, environment and many other factors, electromagnetic radiation will only do harm to human health if it exceeds a certain intensity. This truth, like light, sound and current, will not cause harm to the human body under moderate working conditions. Only when the human body receives powerful electromagnetic waves for a long time and in large doses will it do harm to health.
During the operation, many mobile base stations need to ensure that their equipment is in good condition at any time, and provide services for 8.22 million mobile phone users in the city around the clock. Each base station is an indispensable part of the whole mobile phone network. Once any base station stops working, the mobile phones within the range of several hundred meters to more than one kilometer under its jurisdiction will be in a blind area without signal. Legal and safe mobile base stations are an important part of urban infrastructure and should be well treated and protected. As every citizen, we should correctly understand the problem of electromagnetic radiation, eliminate worries and remove unnecessary worries and fears.
