Abstract

The distribution of natural radionuclides in soil samples have been carried out in and around Hassan district, Karnataka, India by using Hyper Purity Germanium (HPGe) detector and natural ambient gamma dose rate were measured using portable GM survey meter ER-709. The activity concentration of radionuclides such as 226Ra, 232Th and 40K in soil samples of the study area are varies from 13.65±0.9 to 64±1.6, 19.43±0.9 to 185.5±1.8 and 197.85±9.8 to 1214±22.4 Bq kg-1 with a mean value of 39.40±1.3, 59.63±1.5 and 591.38±15.8 Bq kg-1 respectively. The radiological hazards such as the radium equivalent activities (Raeq), external hazard index (Hex), internal hazard index (Hin), gamma index (Iγ), gamma absorbed dose and annual effective dose associated with the natural radioactivity in soil samples were calculated and compared with global average values.

印度卡纳塔克邦哈桑地区土壤样本中的天然放射性和放射性危害评估

在印度卡纳塔克邦哈桑县及其周边地区，利用高纯锗（HPGe）探测器对土壤样本中天然放射性核素的分布情况进行了研究，并利用便携式伽马射线测量仪 ER-709 对周围环境的天然伽马剂量率进行了测量。研究地区土壤样本中 226Ra、232Th 和 40K 等放射性核素的放射性活度浓度分别为 13.65±0.9 至 64±1.6、19.43±0.9 至 185.5±1.8 和 197.85±9.8 至 1214±22.4 Bq kg-1，平均值分别为 39.40±1.3、59.63±1.5 和 591.38±15.8 Bq kg-1。计算了土壤样品中天然放射性的放射性危害，如镭当量活度（Raeq）、外部危害指数（Hex）、内部危害指数（Hin）、伽马指数（Iγ）、伽马吸收剂量和年有效剂量，并与全球平均值进行了比较。
