Uranium Concentration in Drinking Water and the Age-dependent Radiation Exposure in Chengalpattu District of Tamil Nadu, India.
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.
