Abstract

This article focuses on the measurement and analysis of radon (^222Rn) and thoron (^220Rn) exhalation rates and indoor concentrations in the tectonically active Ghuttu village of the Garhwal Himalayas, India. The study found that both ^222Rn mass exhalation and ^220Rn surface exhalation rates, as well as indoor concentrations of these gases, exceed global average values, likely due to the region’s unique geology and the presence of the Main Central Thrust (MCT) fault. Despite elevated levels, the indoor radon and thoron concentrations remain below the International Commission for Radiological Protection’s recommended safety limits, indicating no significant health risk. The research also highlights that indoor radon/thoron levels are influenced by factors beyond soil exhalation rates, including building materials and ventilation conditions.
