Abstract
This study reports the 222Rn, 220Rn, and their progeny concentration in Shivamogga district by using SSNTD’s based pin hole dosimeters and deposition-based progeny sensor. The average indoor 222Rn and 220Rn concentration varies from 8.14 to 146 Bq m−3 and 13.01 to 157 Bq m−3 with a mean value of 60.61 and 61.77 Bq m−3. The EEC for 222Rn and 220Rn ranges from 1.55 to 19 Bq m−3 and 0.44 to 6 Bq m−3 with a mean value of 7.29 and 2.66 Bq m−3. The annual average equilibrium factor for 222Rn is well within the global mean values of 0.4, while the thoron is bit higher than specified global mean values of 0.02. The annual effective dose varies from 0.31 to 2.5 mSvy−1 with a mean value of 1.1 mSvy−1.
