Electromagnetic radiation pollution has been listed by the United Nations as one of the four major human pollutions alongside water pollution, air pollution and noise pollution. Especially now that mankind has entered the information and data era, communication signals, data transmission, electrical products, transmitting base stations, etc. are everywhere. The electromagnetic radiation environment we live in has indeed become very complex, and electromagnetic radiation pollution has to be paid attention to. But now, under what circumstances and to what extent electromagnetic radiation will harm the human body, the scientific community lacks sufficient data research, especially clinical data support, but it is common knowledge that electromagnetic radiation is harmful. It is common knowledge in all walks of life that the radiation in the computer room is relatively strong, and the key is how to protect it; before the 1990s, our country also gave radiation protection subsidies to people working in the computer room, which meant more money, but there was no benefit. Law. After 2008, anti-radiation coatings with wave-absorbing technology (transformed from military stealth technology) appeared on the market, and there were models specifically designed for electromagnetic radiation protection in computer rooms. Such coatings can not only reduce the electromagnetic radiation value in the computer room and protect the human body, equipment, and the environment, but can also prevent electromagnetic radiation from leaking out of the computer room and affecting the health of people outside. The brand you mentioned, Paimon, has a lot of reports on the Internet. It seems to be good. It has good sales on Tmall and JD.com. There are also reports on the Internet that some government projects use Paimon anti-radiation coating. At present, the main ones in China are This brand is making anti-radiation paint, and it is said to have an exclusive invention patent. I also found similar products in Germany and the United States, and they are expensive. The overall effect of the absorbing type is definitely much better than that of the reflective type. After all, after painting, it has some effect both indoors and outdoors. If it only costs a little money, I think it is still a good deal. These are my opinions and suggestions, I hope they are helpful to you.
