Answer:
The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently when the whole body is exposed.We consider that radio waves, after these evidences, are dangerous (especially for long exposition) for human body because, even if they are not unhealthy in a short period, they can cause cells' death by apoptosis and necrosis and DNA damage. Thus they can cause organs failure and generalized problems to organism
