The uranium concentration in drinking water samples collected from areas of Punjab and Himachal Pradesh has been measured using inductively coupled plasma mass spectrometry. The sources of water comprise hand pumps and tube wells. The uranium concentration lies in the range of 1.24-45.42 µg l(-1) with a mean value of 14.91 µg l(-1) in drinking water samples from Punjab and 0.56-10.11 µg l(-1) with a mean value of 2.17 µg l(-1) in Himachal Pradesh. The measured uranium content in 4 % water samples from Punjab has been found to be higher than the limit of 30 µg l(-1) recommended by the World Health Organization (WHO) and US Environmental Protection Agency. However, the uranium concentration in all the water samples from Himachal Pradesh is well below the recommended limit. The annual effective dose associated with drinking water due to uranium concentration is estimated from its annual intake using dosimetric information based on International Commission on Radiological Protection 72. The resulting value of the annual effective dose from drinking water sources is in the range of 0.33-37.78 µSv, which is well within the limit of 100 µSv recommended by the WHO.
已使用电感耦合等离子体质谱法测量了从旁遮普邦和喜马偕尔邦地区采集的饮用水样本中的铀浓度。水源包括手压泵和管井。旁遮普邦饮用水样本中的铀浓度在1.24 - 45.42微克/升范围内，平均值为14.91微克/升；喜马偕尔邦的铀浓度在0.56 - 10.11微克/升范围内，平均值为2.17微克/升。已发现旁遮普邦4%的水样中测得的铀含量高于世界卫生组织（WHO）和美国环境保护局建议的30微克/升的限值。然而，喜马偕尔邦所有水样中的铀浓度均远低于建议限值。根据国际放射防护委员会第72号文件中的剂量学信息，通过铀的年摄入量估算了因铀浓度导致的与饮用水相关的年有效剂量。饮用水源产生的年有效剂量值在0.33 - 37.78微希沃特范围内，这完全在世界卫生组织建议的100微希沃特限值之内。
