Natural radionuclides are universally spread and can be found in varying levels in rock, soil and water depending on the geology. A potential health threat may be caused by them to humans on consumption of water, food and inhalation of air due to the presence of radionuclides. In the present study, an attempt has been made to study the distribution of 238U, 226Ra, 222Rn and 210Po in groundwater samples of Kodagu district, India. The activity concentrations of 238U, 226Ra, 222Rn and 210Po were found to vary from 0.44 to 8.81 μg L-1, 0.71 to 7.66 mBq L-1, 1.54 to 9.61 Bq L-1 and 0.47 to 4.35 mBq L-1, respectively. The associated dose due to radiation was assessed and was observed to be below the recommended standards. The total effective dose to the population was calculated and was found to be less than the recommended WHO standard of 100 mSv.
天然放射性核素广泛存在，根据地质情况，在岩石、土壤和水中的含量各不相同。由于放射性核素的存在，人类在饮用、食用和吸入这些水、食物和空气中的放射性核素时，可能会对健康造成潜在威胁。在本研究中，我们试图研究印度卡纳塔克邦地下水样本中 238U、226Ra、222Rn 和 210Po 的分布情况。结果发现，238U、226Ra、222Rn 和 210Po 的活度浓度分别在 0.44 到 8.81μg/L、0.71 到 7.66mBq/L、1.54 到 9.61Bq/L 和 0.47 到 4.35mBq/L 之间变化。评估了由于辐射产生的相关剂量，结果表明低于推荐标准。计算了人群的总有效剂量，发现低于世界卫生组织推荐的 100mSv 标准。
