Abstract: There is a strong perception relating to existence of a high level of non-ionizing electromagnetic radiation in the vicinity of base station antennas. In the present paper, electromagnetic radiation from base station antennas installed for various wireless communication purposes has been investigated based on equivalent isotropically radiated power calculations. For this purpose, a typical wireless communication site has been selected where GSM, CDMA, 3G/UMTS, and WiMAX antennas are installed. The overall ratio of equivalent isotropically radiated power (EIRP) and threshold EIRP combining all services at this particular site has been calculated at ground level and nearby buildings. It has been found that the ratio of EIRP and threshold EIRP is less than unity and thus, the particular site is normally compliant and does not impose any adverse health effects. For general public, the exclusion zone (compliance distance) from GSM, CDMA, 3G/UMTS, and WiMAX antennas have been found at 7.30, 6.076, 7.436, and 6.861 m, respectively.
