Studies on the effects of EM radiation on human body

Abstract

A complete electromagnetic and thermal analysis has been performed considering the head of a subject exposed to EM radiation and focusing the attention on important organs like the pinna skull brain Attention has first been posed on particular head model and a comparison between the absorbed power distribution and steady state temperature increases has been carried out The influence of different microwave sources on the power of 0mW 600mW and 1000mW maximum temperature increase are obtained in the ear gray matter and skull vary from 0 250C to 0 60C 0 150C to 0 2150C and 0000050C to 10C respectively These steady state temperature increases are obtained after about 40 minutes of exposure with a time constant of approximately 6 minutes The rise in the use of wireless communication devices has determined an increased concern for user s health effects due to the field emitted by the handheld terminals When a wireless device is working, the transmitting antenna is placed very close to the user s head where a substantial part of the radiated power is absorbed This project aims to develop a complete newlineestimation of specific absorption rate SAR considering the head of a subject exposed to various kinds of wireless devices The simulator used in this project is EMPIRE XCcel 5 1 newline
