Now WeChat is very popular, including WeChat and other means of communication will use wireless Internet access, then the radiation hazards of wireless Internet access will be paid attention to. Nowadays, the coverage of wireless Internet services in cities is getting higher and higher, and wifi access points can be seen everywhere, so how much radiation is generated by these wireless network access points? The British Health Protection Agency has estimated that even if a distance from the body of the wireless router is open all year round, it 1 year of radiation generated by the radiation is probably only equivalent to playing a few minutes of cell phone radiation. Of course the above is only to consider the wireless router end of the radiation, if you often use wireless Internet, but also to consider the laptop end of the radiation. Wireless router antennas stand straight up outside, very conspicuous, inevitably let people with radiation phobia look after the imagination, the heart of suspicion. But in fact, for wifi users, wireless Internet radiation is not the main source of those who look “very professional radiation” router, but in the hands of their own laptops when the Internet. So, how does the laptop’s wireless Internet capabilities and cell phone radiation size compared to it? According to the British Health Protection Agency research, laptop wireless Internet radiation absorption rate SAR value is only 1% of the use of cell phones when answering the phone, which is the main reason or the above-mentioned distance. Because the phone can be close to the brain, while the laptop is still some distance from the body. However, when we wireless Internet access to use a few hours, cell phone calls once just a few minutes, taking into account the length of time, the amount of radiation from the laptop wireless Internet access and cell phone radiation should probably be in an order of magnitude. Whether laptops or cell phones, their radiation values are usually at the level of milliwatts per square meter, well below the safety limit of 10 watts per square meter set by the International Commission on Non-Ionizing Radiation (this upper limit is just a precautionary safety limit, not that more than this value, you will get sick, only a slight health risk). As with cell phone radiation, the radiation generated by the router and laptop end of wireless Internet access is within the safe range and there is no need to panic. Is wireless Internet scary? Is there any radiation? The regulations of China Radio Regulatory Commission: the transmitting power of wireless LAN products cannot be more than 10 milliwatts, while the standards of other countries are relatively lenient, for example: the upper limit of transmitting power of wireless LAN products in Japan is 100 milliwatts, some countries in Europe and America is about 50 milliwatts, while the power of wireless network card is generally below 10 milliwatts. Wireless devices are usually far away from human body as well, reaching the human body generally less than 1 milliwatt. Another pair of human radiation in wireless network comes from wireless AP or wireless router that transmits wireless signal, but the transmitting power of wireless LAN access point AP is generally not more than 100 milliwatts, so the impact on human is also much less. Therefore, regardless of laptops or cell phones, their radiation values are usually at the level of milliwatts per square meter, which is far below the safety limit of DD10 watts per square meter set by the International Commission on Non-Ionizing Radiation. How to avoid the harm caused by wireless radiation Although the radiation of wireless networks is very weak, we do not need to worry too much, but it is still necessary if we can reduce human exposure to radiation through some small ways in our daily lives. Below we have compiled some suggestions for your reference that can minimize radiation. Away from the old and weak people wireless network radiation depends mainly on the transmitting power, the closer to the wireless transmitting point the stronger the radiation, so you should put the wireless router, wireless AP placed in a place far away from people, far from the bedroom. Try to avoid the elderly, children and pregnant women close, long exposure to wireless routers and other equipment. The regular manufacturers of wireless routers regular manufacturers of wireless routers in the factory are subject to health departments, environmental protection departments and other relevant tests for human injury, the amount of radiation will also be within the standard regulations. Some unqualified wireless routers, because they have not undergone the strict testing of the relevant standards, the radiation will also increase accordingly, which will produce certain harm to our bodies. Therefore, when buying a router must choose the regular manufacturer’s products. Wireless devices are not used to turn off the wireless router or AP if temporarily not used to turn off the power, on the one hand, can reduce radiation, on the one hand, can save power. And now most laptops have built-in wireless network card, if you do not use the wireless network, then disable it, the operation is to right-click on my computer, in the properties of the device manager to find the wireless network card, select disabled. The indoor do not use high-powered wireless AP In order to increase the transmission distance of wireless devices, many manufacturers provide high-powered wireless AP, these devices are generally for outdoor use, but some friends are obsessed with the pursuit of transmission range and penetration capacity, outdoor AP for indoor use, which undoubtedly increases the radiation of wireless devices to people, is not desirable. Laptop wireless Internet do not be too close to the body some friends in the experience of wireless Internet fun, holding a laptop randomly find a place to sit, the book to the lap on the wireless Internet surfing, watching movies, so that the laptop’s wireless network card is closer to the body, radiation is slightly larger, and also easy to fall bad book, should try to avoid. Avoid cross-radiation When choosing wireless devices in the room, pay attention to avoid wireless products too close to the audio, television and other electronic equipment to prevent interference with each other to produce other radiation. Strengthen physical exercise, enhance their own resistance to the same energy of radiation, the impact on different people are different. Strong resistance to their own ability to offset the radiation than weak resistance to a lot of people, so in the correct understanding of wireless equipment radiation problems, but also through physical exercise to improve their own resistance.
