Uranium concentration has been measured in drinking water samples from the Bathinda district. It ranges from 2.4 to 529 µg/l with a mean value of 120 µg/l. The mean uranium kidney burden for children and adults is 0.0838 and 0.059 µg U/g, respectively, which crosses the safe limit of 0.02 µg U/g. The mean values for skeleton burden are 1925.7 µg for children and 4108.2 µg for an adult. These values are 32 and 69 times higher than the skeleton burden of 59.4 µg for a normal adult. Radiological and chemical risk is also found to be higher than the recommended values. The mean effective ingestion dose for different age groups and genders is 188.2 µSv/y, while the safety limit is 100 µSv/y. The dose to the kidney, bone surface and bone marrow has also been evaluated. The observed values of the studied parameters show that people of this area may be at higher health risks corresponding to the intake of water; children may be the most affected.
已对巴辛达地区饮用水样本中的铀浓度进行了测量。其范围为2.4至529微克/升，平均值为120微克/升。儿童和成人的平均肾脏铀负荷分别为0.0838和0.059微克铀/克，超过了0.02微克铀/克的安全限值。儿童骨骼负荷的平均值为1925.7微克，成人为4108.2微克。这些值分别比正常成年人59.4微克的骨骼负荷高32倍和69倍。还发现辐射和化学风险高于推荐值。不同年龄组和性别的平均有效摄入剂量为188.2微希沃特/年，而安全限值为100微希沃特/年。还评估了对肾脏、骨表面和骨髓的剂量。所研究参数的观测值表明，该地区的人群可能因摄入该水源而面临较高的健康风险；儿童可能受影响最大。
