Measurement of Radon Concentration and Evaluation of Total Dose in Drinking Water of Chikmagalur City, Karnataka

  • Research Article
  • Published:
Journal of the Geological Society of India

Abstract

In the present study, radon concentrations were measured in 31 drinking water samples collected from different locations of the Chikmagalur city, Karnataka state, India, using emanometry technique. The measured radon concentrations ranged from 0.51 ± 0.1 Bq l−1 to 151.98 ± 3.5 Bq l−1 with an average value of 22.72 ± 1.1 Bq l−1. From this study, it is evident that 61% of drinking water samples have radon levels higher than the maximum contaminant level of 11 Bq l−1 recommended by EPA. The estimated total annual effective dose from three locations of the studied area was found to be higher than the safe limit of 0.1 mSv y−1 recommended by WHO and EU Council.
