Abstract

The concentrations of Ra-226 and Rn-222 were measured in ground water samples of Davanagere district, Karnataka state, India using emanometry technique. Activity of Ra-226 and Rn-222 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 Rn-222 in water was found to vary from 0.15 to 1.00 mSvy(-1) with an average of 0.49 mSvy(-1).
