Cell Phones Charlotte Protest Blocked

Whether any kind of electromagnetic wave transmitting equipment is harmful to the human body depends on the human body’s specific absorption rate of electromagnetic waves. The highest radio frequency radiation safety standard SAR recognized by the International Commission for Non-Ionizing Radiation Protection is 2.0, and my country’s standard is 1.5. The transmission power of the current wireless communication station transmission tower is generally 40W~50W, and the specific absorption rate of the human body to electromagnetic waves is below 1.0 when the distance from the transmission tower is 20 to 30 meters. The Cell Phones Charlotte Protest Blocked equipment used in the examination room is a micro-power device, and its transmit power is generally less than 3W, and it is used in the corridor outside the examination room. In this case, the human body's specific absorption rate of electromagnetic waves is minimal. Therefore, the radio mobile phone jammer used in the examination room does not pose a hazard to human health. cell phone jammer
