Soil surveillance provides information on long term contamination trends and environmental radionuclide concentration in undisturbed locations. Activity concentration was measured for ⁴⁰K, ²³⁸U and ²³²Th in soil around the proposed U mining site. Enviornmenal increment value were calculated for each radionuclide where the values ranges from 56.2–205.3 Bqkg^-1 for ⁴⁰K, 33.6–190.3 Bqkg^-1 for ²³²Th and 12.2–321.8 Bqkg^-1 for ²³⁸U with 6 % uncertainity. The calculate values are less than geometric mean values. The lower geometric standard value (<2) suggests that the spread within the data is less and the calculated value lies close to real activity concentration prevailing in the area.
