This paper presents the concentration of uranium in 67 groundwater samples of Chamarajanagar district, Karnataka, India, estimated using an LED fluorimeter. The age-dependent ingestion dose to the population of the district is also studied. The concentration of uranium in groundwater varied from 0.20 to 57.50 μg L-1 with an average of 4.40 μg L-1. The annual ingestion dose due to uranium varies from 0.18 to 142.68 μSv y-1, with an average of 7.11 μSv y-1. The ingestion dose received by the population in the study area is less than the recommended level of 100 μSv y-1 by the World Health Organization (2011).
本文使用 LED 荧光光度计测定了印度卡纳塔克邦查马拉贾纳加尔区 67 个地下水样本中的铀浓度，并研究了该地区人口随年龄变化的内照射剂量。地下水中铀的浓度范围为 0.20 至 57.50μg/L，平均值为 4.40μg/L。由于铀摄入而导致的年摄入量从 0.18 至 142.68μSv/y 不等，平均值为 7.11μSv/y。研究区域内的人群所摄入的剂量低于世界卫生组织（2011 年）建议的 100μSv/y 水平。
