Abstract: This study assesses the direct body dose exposure of dwellers to outdoor background radiation in selected areas of Wushishi Local Government Area (LGA), Niger State, Nigeria. Measurements were conducted GQ GMC-500+ Nuclear Radiation Detector Monitor Dosimeter and a GPS obtained from Physical Sciences Department, Niger State Polytechnic Zungeru. The study recorded radiation dose rates in eighty (80) locations within Wushishi LGA. The highest radiation levels were observed at Dangote Company (0.20–0.21 µSv/hr), Gudugi (0.20 µSv/hr), Water Board (0.20 µSv/hr), and Tudun Wada (0.20 µSv/hr). The lowest recorded levels were at Sabon Gari (0.16 µSv/hr), River Basin (0.16 µSv/hr), and Takashanya (0.15 µSv/hr). Detail of the result is presented in Table 7.1. The mean value was 0.18 µSv/hr. The results indicate variations in background radiation levels, with some locations exhibiting higher readings than others. However, all recorded values remain within the safe limit recommended by the International Commission on Radiation Protection (ICRP). The study underscores the need for continuous monitoring of environmental radiation and further assessment of Naturally Occurring Radioactive Materials (NORMs) in both indoor and outdoor environments.
