Study of soil-gas and indoor radon concentration in a test village at Tehri Garhwal, India

Radon and progeny concentrations in indoor air, radon exhalation rates and radon concentrations in soil–gas were measured at various locations in a test village at Tehri Garhwal, India. The aim of this study is to understand inter-correlations of radon species in different media. Indoor radon and it...

Zusammenfassung:Radon and progeny concentrations in indoor air, radon exhalation rates and radon concentrations in soil–gas were measured at various locations in a test village at Tehri Garhwal, India. The aim of this study is to understand inter-correlations of radon species in different media. Indoor radon and its progeny concentrations were observed higher in winter and lower in summer season. The annual average values of radon and thoron equilibrium factors were calculated to be 0.33 and 0.07, respectively. Radon and its progeny were found to contribute 66% of the total annual inhalation dose. Soil-gas and indoor radon concentrations, and radon exhalation rates were found to be positively correlated with each other.
