Radon and its progeny are the main contributors in the radiation dose received by general population. The indoor radon and thoron progeny levels in Pathsala area of Bajali subdivision of Assam, have been carried out using LR-115(type-II) Solid State Nuclear Track Detectors in Plastic twin chamber dosimeter cups (BARC type). The results of the measurement of radon and thoron progeny levels in different types of R C C (Reinforced Cement Concrete) dwellings for one complete year in four quarters are presented in this paper. The measured indoor radon progeny levels are found to vary from 0.33 to 0.43 mWL with a mean value 0.38 mWL and the thoron progeny levels were found to vary from 0.07 to 0.127 mWL with a mean value 0.09 mWL.Keywords
