In this study, measurement of radiofrequency exposure due to cellular transceiver base station antennas was carried out. Both far and near field measurements of electric field and magnetic field level were made around selected transceiver base station antennas in selected South-South States Nigeria, with the aid of frequency-dependent equipment (CORNET, Electrosmog meter ED78S EMF RF/LF Dual mode model). The results obtained were analysed using thermal related indices such as specific absorption rate (SAR) with peak value in cerebrospinal fluid-CSF (0.095358W/kg), temperature rise with peak also in CSF (0.008381 oC). These results were compared with threshold values of 2 W/kg and 0.08 W/kg for SAR (over the head and whole body respectively), and 1oC for temperature rise as set by International Commission of Non Ionizing Radiation Protection (ICNIRP). The results indicate that none of the network operators in the study area have SAR above the recommended threshold value with the worst case observed in Calabar.
