Background: All human beings and living organisms are exposed to natural radiations on daily basis, which is mainly due to the activity concentration of primordial radionuclides ²³²Th, ²³⁸U and their products of decay together with the natural radionuclide ⁴⁰K present in the earth’s crust. Materials and Methods: A total of 59 soil samples were collected around the banks and surroundings of the Lancaster dam using an auger at a depth of about 0.75 meters from the top surface. The samples were analysed using low background co-axial n-type High Purity Germanium (HPGe) detector of high-resolution and the resulting spectrum were analysed using Canberra Genie software. Results: This study revealed that the activity concentration values are in the order of ²³²Th <⁴⁰K<²³⁸U in all sampling sites. A statistical analysis based on Pearson correlation showed a positive correlation between the radiological parameters and the two primordial radionuclides ²³²Th, ²³⁸U and the natural radionuclide ⁴⁰K. Conclusion: This implied that the two primordial radionuclides ²³²Th, ²³⁸U and their products of decay including the natural radionuclide ⁴⁰K contribute to the emission of gamma radiation in all the locations of the study area. The calculated ²³⁸U/²³²Th concentration ratio in soils of present study was almost six times higher compared with different countries of the world.
