| Abstract: | Concentrations of radon in drinking water collected from 32 locations of Hemavathi river basin, Karnataka, India have been measured by emanometry method. The radon concentration in water ranged from 2.7 ± 0.1 to 138.5 ± 1.5 Bq l−1 with a geometrical mean of 25.3 ± 1.1 Bq l−1. The study revealed that about 82.35% of drinking water samples contained radon concentration more than 11.1 Bq l−1, the limit is fixed by Environmental Protection Agency. Among the different parameters measured, concentration of radon showed weak correlation with chloride and no correlation with alkalinity, pH, nitrate, sulphate, fluoride and total dissolved substance. |
