Assessment of SAR in a human exposed to GSM electromagnetic fields

Exposure to celular mobile communication electromagnetic fields has raised public concern regarding possible adverse effects to people exposed to such radiation. At frequency 900 MHz the most important parameter used to assess human exposure to electromagnetic fields is SAR (Specific Absorption Rate). In this paper are addressed two exposure scenarios: • Human exposure to 900 MHz GSM base station electromagnetic fields, whereby with EMR-300 is measured field strength on different points located meters away from base station antenna. Using SAR prediction formula we have calculated induced SAR values for people located near base station antenna • Human exposure to mobile phone GSM electromagnetic fields, whereby with a software (FDTD code) have simulated human head exposure to mobile phone radiation and have calculated Spatial Peak SAR over 1 gr and 10 gr of human body biological tissues. SAR is calculated for human of middle age, no gender or age distinction. Obtained results are presented graphically and tabulary and are compared with ICNIPR Guidelines.
