Abstract

Daily exposure to GSM electromagnetic fields has raised public concern of possible adverse health effects to people living in the vicinty 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 papers are presented measurements of incident electric field and obtained results are used for numerical prediction of SAR. Measurements of field strength and power flux density are performed on locations few meters away from base station antenna, in different levels, with and without usage of mobile phones, during day and in peak hours of GSM system usage. Results are compared with ICNIPR Guidelines, IEEE and CENELEC standards.
