On December 4th, the Ministry of Industry and Information Technology of China finally issued a 4G license. For operators, the first thing to do after getting a license is to upgrade the signal base station, which also makes the public worried. In the end, how wide is the radiation range of the signal base station? Will the radiation of the signal base station affect the health of the human body?
Under the Zhangye Shengping commercial base station in Chancheng District, Tang’s engineer from the Chancheng District Radio Committee showed the reporter the radiation data of 0.05V/m on site. According to the "Environmental Electromagnetic Wave Sanitation Standard" formulated by the state, when the radiation value reaches or exceeds the dangerous standard of 6.14V/m, it will have adverse effects on the human body. It has been found that the microwave oven has a radiation of up to 9.1 v/m, which is 182 times the radiation value of the base station.
4G network base station radiation value will be lower
Yesterday, 11 25-hour netizens who volunteered to participate in the base station radiation test activities. Under the Zhangye Shengping commercial base station in Chancheng District, Tang’s engineer from the Chancheng District Radio Committee showed the reporter the radiation data of 0.05V/m on site.
Tang engineer said that according to the "Environmental Electromagnetic Hygienic Standards" formulated by the state, the lower the measured radiation value, the weaker the radiation intensity, and the radiation value will reach or exceed the dangerous standard of 6.14V/m. The measured data on the spot is far below the dangerous standard. It can be seen that the radiation of the signal base station will not cause harm to the human body. In addition, since the radiation of the base station is parallel, the horizontal distance of 10 meters from the antenna transmitting direction or the vertical distance of 2 to 3 meters is a safe distance that does not affect life.
Zhou Del, network maintenance personnel of China Mobile Foshan Branch, also said that most of the 4G networks are in the high frequency range. Although the network speed is very fast, the coverage of a base station will be smaller than before; this is mainly because the signal power of a single base station is low. The speed of signal attenuation is fast, which means that the radiation will be lower than the previous base station. Therefore, the base station radiation in the 4G era is much lower than in the previous 3G or 2G era, and citizens do not have to worry about the higher frequency of the network. In addition, the signal transmission power between the mobile phone and the base station is dynamically adjusted. The farther away the two are, the higher the power of the mobile phone will be to search for the signal, so it is not as far from the base station as it is healthier.
The highest radiation in microwave ovens in indoor appliances
In addition to the radiation of the test signal base station, 25 hours yesterday, netizens also tested some of the commonly used home appliances under the guidance of the staff of the Chancheng Radio Committee.
The test data shows that the radiation amount of 0.5 m in front of the LCD screen is 0.11 V/m, the radiation amount of 0.5 m on the side is 0.12 V/m, the instant of activation is 0.12 V/m, and the shutdown is 0.11 V / m. The amount of radiation does not cause harm to the human body. The test data of the desktop computer host is relatively high, the front of the host is 0.17V/m, the central operating panel of the main unit is 0.26V / m, the side of the main unit is 0.29V/m, and the back of the main unit is 0.46V/m. The startup and standby states are 0.17V/m, while the desktop power supply wiring is 0.47V/m at the moment of reconnection. This also reminds the office family that it is necessary to maintain a certain distance when using a desktop computer.
In addition, netizens also tested the radiation value of the microwave oven in the home. It was found that the radiation value around the microwave oven was as high as 9.1V/m, which exceeded the safety value of 6.14V/m, which was 182 times of the radiation value of the base station. However, in the household appliances tested in the field, only the test data of the microwave oven exceeded the standard, and the rest of the electrical appliances could be safely used. The air cylinder was 0.2V/m, and the mobile phone standby was 0.07V/m.
Mr. Luo, a 25-hour netizen who participated in the test on the spot, told the reporter: "I used to think that there are bad things in radiation. I can avoid them when I avoid them. After this series of tests, I realized that radiation is actually living. It is ubiquitous and inevitable, but fortunately most radiation does not cause harm to the human body. The word "radiation" will not be too tight in the future."
Tang Gong told reporters that household appliances will have some radiation, but most of them are within the safe range, and daily use will not harm the human body. He reminded the public that it is necessary to avoid sitting in front of the computer for a long time. The time for making a phone call should not be too long. When using a high-radiation appliance such as an induction cooker or a router, keep a distance of more than one meter and reduce the radiation. To the lowest. Information Times reporter Qiu Zuolin
