Abstract
Nowadays mobile communication is one of the most rapidly developing telecommunication systems. In every country, millions of users employ this type of mobile communication. It is the only radiation producing consumer product that people intentionally place against their head for extended time periods. There is irrefutable evidence that mobile phone radiation affects biological mechanisms in the body. This radiation penetrates the head and increases the brain temperature (thermal level) of the user while the phone is in use, also affects protective biological mechanisms in the body. Since the large amount of general population is using the mobile phones, there is a need to determine the level of radiation in respect to the exposure standards (SAR). The purpose of this paper is to calculate the radiation power density of mobile phone, minimum safety distance and find out how mobile phone radiation decreases over short and long distances.
