Whether the walkie-talkie is harmful or not is mainly from the harm of radiation. Theoretically, the greater the radiation, the greater the power, and the longer the communication distance. For example, a walkie-talkie with a communication distance of 5 kilometers has a power of about 5 watts (generally, the transmission power of mobile phones is only 1 watt). The radiation is obviously greater than that of mobile phones. many.
But because walkie-talkie talks intermittently, and only generates high power when transmitting. So compared to mobile phones, the duration is shorter. In addition, when using walkie-talkie, the call is not close to the human body, but is 2 to 5 centimeters away from the human body. Compared with the mobile phone talking against the ear, walkie-talkie has a smaller radiation distance. Therefore, under normal circumstances, using walkie-talkie will not cause harm to the human body.
However, some high-power walkie-talkies, such as a walkie-talkie with a power of 10W, emit 20 times the radiation value of a mobile phone, which will cause harm to the body. The long-term use of high-power walkie-talkies allows the body to deteriorate in high-radiation environments. It turns out that high radiation can cause pituitary dysfunction and many other nerve stimuli.
