Radiation harm is small
Be vigilant about the cumulative effect
The popularity of wireless charging function is becoming more and more widespread, and compared with the traditional way of charging the radiation hazard to be large, the market needs an industry standard to regulate. As the radiation value is relatively small, users can easily ignore, perhaps this is a big misunderstanding.
Radiation standards are still under development
According to the "electromagnetic radiation protection regulations", the average user in 1 day 24 hours, any continuous 6-minute whole-body average of the Specific Absorption Rate (SAR) should be less than 0.02W/kg.
"But this is just a very simple standard for the product-specific relevant provisions are not yet clear. " Ms. Zhao of the Standard Information Service Department of the China Communications Standards Association said. It is understood that the association is developing wireless charging electromagnetic radiation standards, but also is studying the human body exposed to this electromagnetic field radiation assessment method, the specific content has not yet been announced.
Chen Jinqiao, deputy chief engineer of the Telecommunications Research Institute of the Ministry of Industry and Information Technology, said that the traditional cell phone charger (direct charging) is standardized, and wireless charging as an emerging technology, the state should develop industry mandatory standards as soon as possible, so that consumers are informed and refer to the use of the next step to be carried out.
Hazard within the range of tolerance
The lack of standards, so that the popular wireless chargers on the market to drill a "loophole". Donglin Technology Co., Ltd. marketing manager Dai Zishan said that most of the wireless chargers on the market will not be labeled radiation value. "But our products are certified by FCC, CE, Rhos.
The staff of the Department of Communications of the Ministry of Industry and Information Technology (MIIT) said that it is inevitable that wireless chargers have radiation, but since it is already on the market, it means that it certainly meets international standards and will not be very harmful to the human body. And for this point of view, the Ministry of Industry and Information Technology, Telecommunications Research Institute, Terrell Laboratory, the director of any Guili agreed: "Wireless chargers as long as the technical specifications to do, there will be no radiation hazards to the human body."
But there is a key question. Although the wireless charger radiation value is small, but the user is exposed to more and more radiation, this will not produce a "cumulative effect"? For example, wireless chargers, cell phones, WiFi, TV superimposed on the radiation will not be harmful to the human body?
Comprehensive radiation is more harmful
"There is no such comprehensive standard." The staff of the Department of Communications of the Ministry of Industry and Information Technology said, but he personally believes that this should not be a 1 + 1 = 2 problem, "as long as the radiation value of each appliance is within the standard range, it should not be harmful."
And Beijing Indoor Environmental Pollution Detection Technology Center, an engineer surnamed Guan believes that if there are more sources of radiation like these, the harm to the human body may be greater, "If there are elderly children at home, pregnant women and other sensitive people, be sure to minimize radiation."
The difficulty, however, is that such radiation is generally difficult to avoid. "Unless not going to use, for the user itself can not be avoided, it is best not to use at the same time." The staff argued.
Radiation, colorless, tasteless and invisible invisible and unnoticeable: flying in the sky is a wireless signal, indoor use of household appliances, holding a cell phone, tablet, next to a large number of wireless chargers ...... and, at present, there is no way to reduce the radiation, the user does not pay good attention to it now, and in the future, you can only Seek your own good fortune.
