The maximum radiation amount of some models can be as high as 13mW/cm2, which is the national health standardMore than 200 times the limit. When the antenna is close to the ear, the body has a certain absorption of microwave radiation, so it is best to close the ear after 4-5 seconds when calling the phone.
PS. The use of mobile phone radiation protection points of attention: phone headphones: the use of headphones can make the head less than 100 times the radiation. The less the signal, the greater the radiation: when the mobile phone signal is unstable, the transmission power must be increased to ensure normal communication, and the radiation is larger. (refers to the signal grid, the signal quantity that the mobile phone can receive from the base station) Do not put the mobile phone ringing in the ear: the mobile phone has not started the power control at this time, and the radiation is large.
