Abstract
ABSTRACT This investigation aims to evaluate the concentration of dissolved radon in drinking water and to assess the associated radiation doses for infants, children and adults in Bhiwani district of Haryana The radon concentrations were measured in 82 drinking water samples collected from 32 villages/towns in the Bhiwani district. The measurements were performed by RAD7, an electronic radon detector manufactured by Durridge Company Inc. The mean radon concentration ranged between 1.3 ± 0.4 and 13.4 ± 2.2 Bq l−1. The mean radon concentrations from two locations exceeded the maximum contamination level (MCL) of 11 Bq l−1 recommended by United States Environmental Protection Agency. The total annual effective doses due to ingestion and inhalation of radon in drinking water varied from 10.1 to 104.4 µSv y−1 for infants, 5.8 to 59.6 µSv y−1 for children and 6.6 to 67.7 µSv y−1 for adults and the average values were found to be 46.3, 26.5 and 30.1 µSv y−1, respectively.
