With the growing need for communication and internet technological development of wireless communication and development of networks which allow mobile phone users access to internet and communication, this is accompanied by a rise in mobile base station mast which expands coverage area of network connectivity and signal quality. These masts facilities are most times erected very close to residential area which exposes humans and animals to Radiofrequency (RF) radiation which could cause different health issues like carcinogen (group 2B), memory loss, thermal and non-thermal effect. In this research work, the assessment and evaluation of health risk associated with base station mast in Karu, Nasarawa state as case study was investigated using an electrosmog electromagnetic tester to measure the electric field, magnetic field, power density within the range from 10-100m away from the masts facilities of different network providers (MTN, Airtel, 9mobile, Globacom). The Specific Absorption Rate was evaluated and the results from this study showed that the average SAR for the selected base mast station facilities were within the range of 0.012mW/Kg – 0.16mW/Kg and a power density range between 1..083W/m2-4.855 W/m2 which are lower than the recommended limit by the International Commission for Non-Ionizing Radiation Protection (ICNIRP) (0.08W/Kg) for the SAR and 10 W/m2 for the power density respectively and can be concluded that the results from the study showed that RF radiation from this source poise no significant radiological risk to the general public but can cause thermal and non-thermal effect if exposure is consistent.
