The Study Of Radon/Thoron And Progeny Concentration In The District Haridwar, Uttarakhand, India Using SSNTDS
Main Article Content
Abstract
Annual radon and thoron exposure imparts a major contribution to inhalation doses received by the public. we have found the results of Indoor radon and thoron concentrations were measured passively over time in the Haridwar region, with health hazards to residents. In the current study Solid State Nuclear Track Detectors (SSNTDS) based twin chamber dosimeters, i.e. pin-hole dosimeters with LR-115 track detectors, were utilized to estimate Radon (Rn) and Thoron (Rn) gas concentration levels in Haridwar houses. DRPS and DTPS were used for estimating the radon progeny concentration and thoron progeny concentration. The average Radon concentration levels studied in houses were found the values from 15.75 Bq/m3 to 52.13 Bq/m³ and thoron concentrations is found to vary from 9.71 Bq/m3 to 31.89 Bq/m³ and its corresponding geometric mean of Radon and thoron concentration were found 25.58 Bq/m³ and 17.04 Bq/m³.
