Mohankumari The dissolved radon concentration in water samples collected from various aquifers in and around Thirthahalli taluk was measured by employing active technique through Scintillation Radon Monitoring system. The measured radon concentration lies in the range of 0.37 ± 0.05 Bq/l to 87.02 ± 2.11 Bq/l. The resulting annual effective radiation dose to the public, who consume this water, lies in the range of 1.01μSvy−1 to 237.56 μSvy−1. However, no significant change in the radon concentration with respect to seasonal variation was observed in majority of the sample. Few samples show higher radon concentration during summer season and lower concentration in rainy season. All these results are presented in this paper.
