Cell Phone Robocall Blocker App Power Is Relatively Low
Whether any kind of electromagnetic wave emitting device is harmful to human body depends on the specific absorption rate of electromagnetic wave by human body. The highest radio frequency radiation safety standard SAR recognized by the International Commission on Non-Ionizing Radiation Protection is 2.0, and my country's standard is 1.5. At present, the transmitting power of the transmitting tower of the wireless communication station is generally 40W~50W, and the specific absorption rate of the electromagnetic wave by the human body is below 1.0 when the distance from the transmitting tower is 20~30 meters. The Cell Phone Robocall Blocker App equipment used in the examination room is a micro-power device, and its transmission power is generally less than 3W, which is used in the corridor outside the examination room. In this case, the specific absorption rate of electromagnetic waves by the human body is the smallest. Therefore, the Cell Phone Jammer equipment used in the examination room will not cause harm to human health.
