Abstract

Abstract: The current investigation involved collecting and analyzing groundwater samples from the Chengalpattu district in the state of Tamil Nadu. The content of uranium was determined using an LED fluorimeter. The uranium concentration exhibited a range of 0.02 μg L-1 to 2.814 μg L-1, with a mean value of 0.347 μg L-1 and a standard deviation 3.05 μg L-1. The uranium concentration levels calculated in this study are significantly below the recommended limits set by various agencies, including WHO (2011), US EPA (1991), ICRP (1995), UNSCEAR (1982), and AERB (2004), and these limits are used for critical in protecting public health. The annual ingestion dosage from uranium consumption via drinking water is estimated for all age groups and compared to the prescribed limits. The annual uranium intake in drinking water for various age groups ranges from 0.0224 μSv y-1 to 7.0674 μSv y-1. The analysis shows that the doses are far below the recommended safety threshold. The average yearly intake dosage is well below the required threshold, indicating that the drinking water sources in the study region do not pose any harmful health risks related to uranium.

印度泰米尔纳德邦Chengalpattu地区饮用水中的铀浓度和年龄相关的辐射暴露。

摘要：目前的调查包括在泰米尔纳德邦的Chengalpattu地区收集和分析地下水样本。铀的含量是用LED荧光计测定的。铀浓度范围为0.02 ~ 2.814 μ L-1，平均值为0.347 μ L-1，标准差为3.05 μ L-1。本研究计算的铀浓度水平大大低于各机构规定的建议限值，这些机构包括世卫组织（2011年）、美国环保署（1991年）、ICRP（1995年）、联合国科委会（1982年）和AERB（2004年），这些限值在保护公众健康方面至关重要。对所有年龄组通过饮用水消耗铀的年摄入剂量进行了估计，并与规定限值进行了比较。各年龄组饮用水中铀的年摄入量在0.0224 ~ 7.0674 μSv -1之间。分析表明，剂量远远低于建议的安全阈值。平均年摄入量远低于规定的阈值，表明研究区域的饮用水源不构成与铀有关的任何有害健康风险。
