Abstract
The shallow groundwater in Bathinda of Punjab, India, has high uranium (U) concentrations, due to the Quaternary alluvium formed from sediments deposited by weathering of the Himalayan mountains. The present study determined radionuclide distributions (226Ra, 228Ac and 40K) in surface soils and measured the absorbed dose rates in air through a car-borne survey. The absorbed dose rates ranged from 36 to 115 nGy h−1 with an average of 66 nGy h−1. Radiological hazard parameters such as indoor and outdoor annual effective doses were 0.55 mSv y−1 and 0.08 mSv y−1, which were slightly higher than world average values.
印度旁遮普省Bathinda浅层地下水中铀(U)含量高，这是由于喜马拉雅山脉风化沉积形成的第四纪冲积物所致。本研究确定了放射性核素（226Ra、228Ac和40K）在表层土壤中的分布，并通过车载调查测量了空气中的吸收剂量率。吸收剂量率范围为36 ~ 115 nGy h - 1，平均为66 nGy h - 1。室内和室外年有效剂量等辐射危害参数分别为0.55 mSv y - 1和0.08 mSv y - 1，略高于世界平均值。
