Abstract
In the present study, indoor radon (222Rn), thoron (220Rn), radon progeny (214Po) and thoron progeny (212Po) activity concentration have been measured in a region around the National Capital Power Station, Dadri, Uttar Pradesh, India. The mean values of the 222Rn, 220Rn and their progeny in the studied region are found to be 22.1 ± 10.0 Bqm−3, 48.6 ± 13.5 Bqm−3, 8.8 ± 4.8 Bqm−3 and 0.49 ± 0.15Bqm−3 respectively. The annual inhalation dose estimated from the observed concentrations varies from 0.29 ± 0.04 to 2.06 ± 0.121 mSv with a mean value of 0.75 ± 0.32 mSv and is well within the reference level. It has also been observed that 212Po is a significant contributor (= 18.7%) to the total annual inhalation dose. Seasonal variations of 222Rn, 220Rn, and their progeny have also been reported.
