Natural Radionuclides Distribution in the Granitic Rocks and Soils of Abandoned Quarry Sites, Abeokuta, Southwestern Nigeria
A.M. Gbadebo

Abstract:
This study determined the concentrations of natural radionuclidess in the crystalline bedrocks and soils of the selected abandoned quarries in Abeokuta area and their possible health impacts. The results of the radionuclide from rocks in the study area indicated varying concentration of 238U, 232Th and 40K. Among the quarries, rocks from AGI (Saje quarry) have the highest concentration of all the radionuclides (238U, 232Th and 40K) while the values are lower in the samples from Colonial quarry (Adigbe). However, 40K has the highest concentration in the rocks of the abandoned quarry sites, followed by 238U and least for 232Th. This trend is maintained in both the surface and subsurface soils with slight modification. It can therefore be inferred that the radionuclides types observed are based on the local geology of the study area and these radionuclides will serve as possible sources of radiation to the local quarry workers and the nearby residents alike.
