| Abstract | ||
| The worldwide use of cellular phones has generated public concern about exposure to the microwave radiation associated with these phones. The probable biological effects due to the use of mobile phones can be regarded as a result of energy absorbed by the head that may damage the brain and nervous tissues. This paper discusses the probable health effects of mobile phones radio emissions, and presents a theoretical method to calculate the specific absorption rate (SAR) in human head exposed to the microwaves of frequency range used in GSM-900, and GSM-1800 mobile phones. A mobile phone with a single direction antenna as an electromagnetic fields source positioned near the head is assumed, and a four layers head model is constructed to calculate the penetration depth in human head, to analyze the SAR and heat distribution in head tissues. | ||
