Description

The concentrations of 226Ra and 222Rn were measured in ground water samples of Davanagere district, Karnataka state, India using emanometry technique. Activity of 226Ra and 222Rn in groundwater varied from 15.6 ± 3 to 68.9 ± 5 mBql-1 and 37 ± 4 to 245 ± 8 Bql-1 respectively. More than 53% of the water samples showed higher radon concentration compare to standard safe limit of 100 Bql-1 prescribed by WHO. Effective dose to the public due to 222Rn in water was found to vary from 0.15 to 1.00 mSvy-1 with an average of 0.49 mSvy-1. (author)
