Abstract
This study assesses the ambient gamma dose rate and radon concentration in drinking water at different locations in few coastal taluks of Uttara Kannada district. The ambient gamma dose and 222Rn activity in drinking water has been estimated by using micro R survey meter and Emanometry technique respectively. The annual effective doses ranges from 0.39 to 0.82 mSvy−1 with a geometric mean value of 0.55 mSvy−1 and it is slightly higher than the world average value. 222Rn activity in drinking water vary from 3.34 ± 0.22 to 160.18 ± 1.84 Bql−1 with mean value of 25.07 ± 0.86 Bql−1. Annual average ingestion dose due to consuming water are well below the WHO and EC suggested action level of 100 µSvy−1.
