The general public is concerned about the potentially dangerous health effects of human exposure to Electromagnetic Radiation (EMR) released by Phone base stations. Concerns about the purported detrimental effects of Electromagnetic Field (EMF) radiations emitted by Phone base transceivers prompted protests against the construction of phone base stations (BTS). As a result, measuring levels of EMF exposure to the population and potential hazards is critical. In this paper, a wideband TES-90 Electro smog meter is used to measure public exposure to electromagnetic radiation from the BTS at several places in Abeokuta. After surveying using a Global Positioning System (GPS) meter, measurements are taken from 62 base stations in Abeokuta. The maximum and average power density from all of the investigated base station antennas was compared with the International Commission on Non-Ionizing Radiation for public exposure (ICNIRP) to get accurate results. From the given input, the greatest power density for the system of mobile telecommunication signal at BTS is 9.02 10-4 mWcm-2 at a 2m radius, while the mean value of power densities collected from all base stations is 3.61 10-4 mWcm-2 at 2m radius which is significantly lower than the 1 mWcm-2 limit imposed by the International Commission on Non-Ionizing Radiation for public exposure (ICNIRP). The measurement is within the ICNIRP-recommended limiting standard (1mWcm-2). In this study, it was found that radiation exposure from BTS poses no health risk and does not appear to have any known harmful effect on human health.
