摘要：
The present study utilizes the latest solid state nuclear track detectors based single entrance radon-thoron twin chambers, direct radon/thoron progeny sensors to measure indoor radon, thoron, and their progenies. From the measured values of radon, thoron and their progenies concentrations, radon and thoron equilibrium factors and annual effective inhalation dose have been estimated. The mean values of equilibrium factor for radon and thoron in studied dwellings have been found to be 0.52 ± 0.19 and 0.013 ± 0.006 respectively. The mean value of annual effective dose is estimated as 1.02 ± 0.41 mSv. Seasonal and different types of house wise variations of radon, thoron and their progenies are discussed in detail.
