Human Exposure Assessment in the Vicinity of 900 MHz GSM Base Station Antenna

Daily exposure to GSM electromagnetic fields has raised public concern of possible adverse health effects to people living in the vicinity of base station antennas. International guidelines and standards established for limiting human exposure to electromagnetic fields are given in two categories: basic restrictions (SAR, induced current density and induced power density) and reference levels (free space electric field intensity, magnetic field intensity and power density). In order to check compliance for both categories, in this paper are presented measurements of incident electric field and obtained results are used for numerical prediction of SAR.
