An evaluation of the level of background radiation was carried out at Shanu village in Minna, Niger state, Nigeria. A portable Geiger-Mueller tube-based environmental digital radiometer (Digilert Nuclear Radiation Monitor, S.E International, Inc. USA) calibrated by gamma (γ) rays from cesium (Cs) source was used for the measurement. A total of ten (10) points was surveyed across the village for level of background radiation. The radiation dose rate varies from 0.0268mR/hr to 0.0311mR/hr. In all ten points surveyed the mean dose rate was 0.0128mR/hr with a standard deviation of 0.000879mR/hr. This is about 17% deviation from the standard background radiation value of 0.011mR/hr. This result could simply be attributed to natural sources (cosmic and terrestrial) and also the possibility of radionuclide sources in the environment. The average annual effective dose obtained from this study is 1.1213mSv/y which is still less than the current average radiation dose to the world’s population from natural sources of radiation of 2.4mSv/y as reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).
