A radiofrequency radiation (RFR) survey of Alakahia and Choba Communities of Rivers State has been carried out using a Radio Frequency Field Strength meter and a Geographical Positioning System (GPS). The measurements were carried out around twelve GSM base Stations at maximum distance of 100 metres from each base Station. The results obtained showed a range of maximum total power density (TPD) and specific absorption rate (SAR) of between 0.15W/cm2 to 3.13W/cm2and 50.6W/kg to 1050.05W/kg respectively for the twelve surveyed base stations. These results though below the Federal Communication Commission’s recommended permissible limits of 570W/cm2 and 1000W/cm2 (power density) or 1.9 x 105W/kg and 3.4 x 105W/kg (SAR) for GSM 900 and GSM 1800 respectively, some of the values obtained are within the range opined by previous researchers to have possible health side effects when individuals are continuously exposed to RFR and at very close ranges. The public and occupationally exposed people are therefore advised to avoid residing very close to the GSM base stations to avert excessive exposure to radio frequency radiation.
