Electromagnetic radiation control method and related device

Disclosed in the embodiments of the present application is an electromagnetic radiation control method. Said method comprises: acquiring a spacing distance between a user device and a user; and adjusting, according to the spacing distance, an effective isotropic radiated power of a millimeter-wave transmitted by the user device, so that electromagnetic radiation generated by the transmitted millimeter wave satisfies a maximum permissible exposure. The embodiments of the present application further disclose an electromagnetic radiation control apparatus. The implementation of the embodiments of the present application can improve the transmission power and transmission efficiency of a millimeter wave.
