Abstract
The average concentrations of gamma-emitting natural radionuclides 238U, 232Th and 40K in soils from 13 sampling locations around the nuclear research facilities at the Obafemi Awolowo University (OAU), Ile-Ife, have been measured by means of a well-calibrated high resolution gamma-ray spectrometer. Average data on 0–150 mm and 150–300 mm depth distributions in soils have been obtained. The average total specific activity values of 29.1 ± 4.0, 26.5 ± 3.8 and 131.8 ± 32.8 Bq kg −1 for 238U, 232Th and 40K respectively were obtained. The 137Cs concentration in soil samples was below the limit of detection. Average total specific-activity values of 4.2 ± 1.9 and 3.6 ± 2.1 Bq 1 −1 were recorded for 238U and 232Th, respectively, in surface and drinking water.
