Abstract:

The concentration of radionuclides in Zaki-Biam were collected, measured and analyzed for indoor and outdoor exposure rate at different points. The samples were soil collected in Dump site, Farm Land and the Industrial site and measurements of the background radiation were taken using the Geiger counter. Gamma ray spectrometry was used to analyze the radionuclide concentrations of 238U, 232Th and, 40K in the samples. The radionuclide concentrations of 238U, 232Th and 40K varied in the range of 4.72±1.96 to 35.35±2.86Bq/Kg, 14.92±2.57 to 87.30±8.59Bq/Kg and 105.79±9.74 to 874.54±70.83Bq/Kg respectively, indicating the highest concentration of 40K in the farm land. The result further reveals that the concentrations of 40K in the soil samples in all the study areas were higher compared with the global average value of 400Bq/kg. The highest radionuclide concentration of 232Th on the average was obtained at the Industrial site quantified by 43.68±4.69Bq/Kg. Results also indicate that the radionuclide concentration of 238U on the average was greatest at the Farm land (18.48±3.99Bq/Kg) followed by the Dumpsite (13.93±3.64Bq/Kg) and with the least concentration at Industrial site (8.88±2.32Bq/Kg). Results indicate that the farm land (FL7) has the highest dose of 79.14nGyh-. 1 . Interpretation shows that the radioactive level index at some points in all the three sites under study indicated a concentration above the required and standard normal value of unity.
