Assessment of Radionuclide Pollutants in Bedrocks and Soils from Ewekoro Cement Factory, Southwest Nigeria

A.M. Gbadebo and A.J. Amos

Abstract:
The results of the radionuclides analysis in the bedrock (i.e., limestone and shale) and soil samples (surface and subsurface) samples collected from locations around Ewekoro cement factory indicated an average total specific activity values of 7.78±2.74, 8.99±3.90 and 17.63±1.98 Bq kg-1 for 238U, 232Th and 40K, respectively in the surface soils while average total specific activity values of 8.07±2.88, 8.25±3.18 and 16.52±1.98 Bq kg-1 for 238U, 232Th and 40K, respectively were obtained for subsurface soils. Similarly, the average total specific activity values of 91.30±2.33, 5.75±2.57 and 35.86±7.06 Bq kg-1 for 238U, 232Th and 40K, respectively were obtained for limestone bedrock type while values of 3.74±11.42, 5.95±2.26 and 348.20±61.82 Bq kg-1, for 238U, 232Th and 40K, respectively were obtained for the shale bedrock type. From the above, geogenic source of the radionuclides with some anthropogenic implications can be inferred.
