Abstract: The desire in this work is to make an attempt to answer the several questions posed on the safety level of the RF radiated from GSM Base Stations (BSs). In Nigerian some people believed that exposure to radiation from BSs for long period could cause different diseases like cancer, destroys reproductive organs, congenital anomalies, epilepsy and persistent headache and some of the BSs were installed near the home of residence. Power densities were measured in every 10s at 100m and 200m away from GSM BSs installed at Lokuwa/Barama ward Mubi Nigeria few centimeters from home of residence with the view to establish whether exposure to RF would have relationship with Human health. Average amount of power density measured at 100m were 1.48?W/m2, 1.32?W/m2, 1.50?W/m2, at 200m were 1.8?W/m2, 1.87?W/m2 and 2.26?W/m2 with corresponding values of specific absorption rate (SAR) as 0.005, 0.0007, 0.0005, 0.008, 0.006 and 0.0007Kg/m2 for the major GSM Operators in Mubi that is ZAIN, MTN and GLOBALCOM respectively. The analysis shows that the SAR fall far below recommended level when compared with the general public safety guide line for limiting radiation exposure and SAR given by the world health Organization (WHO) and international Commission on non ionizing radiation protection (ICNIRP).
