A survey of the environmental radioactivity in Uyo /5° N, 7° 50 E/, Nigeria has been done for the period 1981 to 1986. An overall average of 8.5±0.5 pCi is the environmental radioactivity for the surrounding air and 8.2±0.4 pCi for the top soil. Airborne α-particles were also measured using CR-39 plastic detectors. The University Campus in Uyo had an overall average α-activity of 75.3±0.8 fmCi while other sectors of the town had an average of 95.2±1.1 fmCi. Our results show a non-uniform distribution of α- and other radioactivity in Uyo.
