With cell phones, cell phone signal jammers does have some radiation.
Phone signal jammers working principle is similar to the phone as it uses the same chip with the phone, but also to transmit electromagnetic signals, so it just like cell phones, will have some radiation on the human body. Is not all the intensity of electromagnetic radiation are harmful to human health? Phone signal jammers degree of harm to the human body and not across the board, it opens with the instrument as well as the length of time the individual physique. In fact, the state of electromagnetic radiation intensity (ie, the field strength) expressly provided safe value. http://www.4gcellphonejammers.com/
State regulations mentioned here, is approved by the State Environmental Protection Administration in March 11, 1988, and in the same year June 1 start of the "electromagnetic radiation protection" (GB8702- 88). The provisions of the electromagnetic radiation occupational and public safety value makes provision for two populations. As the public crowd 30-3000MHz frequency within the range of electromagnetic radiation, in the 24 hours of the day, in any continuous 6 minutes, the mean field strength is not greater than 0.4 W / m.
Formal, with production license of the enterprise, the production of mobile phone shielding device have been tested, the relevant departments of the radiation intensity within safe limits prescribed by the state. Generally applicable to a small space classrooms, meeting rooms and other cell phone signal jammers power is not great, and the location of the installation, there are strict specifications. Such as the hallway wall behind the podium, and the body's distance is usually 2-3 meters, which has led to the electromagnetic radiation hazards to human safety falls within the range of values. 4g cell phone jammer
For a small space, it must not to be lazy, blind introduction of power saving mobile phone signal jammers (shielding effect range is greater than the radius of 50M). "High-power mobile phone signal jammers strong electromagnetic field is also large, require greater distances in order to enter the safe range.
4g cell phone jammer The extent of damage across the board under the shield judgments instrument approach, so regular screening manufacturers quite indignant. With harmful radiation is different, how you can draw parallels? Like cell phones, microwave ovens, televisions have radiation, and some pretty big field, but outside a certain range, within a certain time period of this harm is negligible, the body will not produce irreparable nature damages, so these products will be widely used and has not been abandoned in the community.
