Authors: Niranjan R S, Ningappa C

Abstract: In this study, the annual effective dose exposure in the Yagachi river basin and the distribution of radon activity concentration in drinking water samples are measured. Emanometry method was used to determine the radon concentration in 30 samples of drinking water. The observed radon concentration in drinking water samples ranged from 12.26 ± 0.21 to 118.56 ± 2.65 Bq l-1 with an geometrical mean value of 45.24 ±1.03 Bq l-1. According to this study, all the drinking water samples examined had radon levels are above the USEPA's maximum contamination level of 11.1 Bq l-1. The geometrical mean annual effective dose varies from 33.47 to 323.67 µSv y-1 with geometrical mean value of 123.52 µSv y-1. Annual effective doses of 73% drinking water samples are above the recommended limit of 100 µSv y-1 recommended by World Health Organization.
