Recently, R & D by the success of Yan Qing ROCK radiation mobile phone sets, with a high technological content: not only can let the phone against mobile phone radiation "invisible" to be known as "seeing blocks radiation mobile phone case."
Electromagnetic radiation is the second water pollution, air pollution, noise pollution, the fourth largest source of pollution. Especially the mobile phone radiation, which is closely related to our contact with for a long time away from the past, it is also known as "full of tenderness of the invisible killer." While the mobile phone radiation on human health risk level is inconclusive, but the cell phone radiation harmful to health has been recognized worldwide. It has caused the World Health Organization and national government attach great importance, and have developed a variety of appropriate radiation standards. At present, China mobile phone radiation standard is currently under development.
At present the industry as a kind of mobile phone radiation "firewall" invisible radiation mobile phone sets, R & D success by Yan Qing. This radiation safety of mobile sets using modern information technology, special materials in the kit block electromagnetic waves to pass through, effectively prevent cell phone radiation. According to departments of State authority strong electromagnetic field attenuation 66dB, attenuation of cell phone radiation 2000 times than the original, can effectively protect human health, to lift long-term radiation carry cell phones and psychological burden. At the same time sets the phone has a "stealth" function, when the phone into the phone sets the "invisible area", the phone will "disappear" before calling the voice is "not in service area" or "temporarily unable to connect", Machine master can not answer the phone politely avoided.
