摘要：
The distribution of natural radionuclides in soil samples was carried out in and around Hassan district, Karnataka, India, by using a Hyper Purity Germanium (HPGe) detector, and the portable GM survey meter ER-709 used to measure the natural ambient gamma dose rate. The activity concentration of radionuclides such as 238U, 226Ra, 232Th, and 40K in soil samples of the study area varies from 16 +/- 1 to 72 +/- 2, 13 +/- 1 to 64 +/- 2, 19 +/- 1 to 185 +/- 2, and 197 +/- 9 to 1214 +/- 22 Bq kg-1 with a mean value of 42 +/- 2, 39 +/- 1, 58 +/- 2, and 592 +/- 15 Bq kg-1, respectively. The radiological hazards such as the radium equivalent activities (Raeq), external hazard index (Hex), internal hazard index (Hin), gamma index (I gamma), gamma absorbed dose, and annual effective dose associated with the natural radioactivity in soil samples were calculated and compared with global average values.
