Radionuclide contents and their correlation with radon-thoron exhalation in soil samples from mineralized zone of Himachal Pradesh, India

The radionuclides have been evaluated by utilizing NaI(Tl) gamma spectrometric technique from soil samples, mainly used in construction purposes. Radium equivalent activity from soil samples has been found within the range of 115–196 Bq/kg. Annual effective dose for indoor and outdoor environment ha...

Description
Summary:The radionuclides have been evaluated by utilizing NaI(Tl) gamma spectrometric technique from soil samples, mainly used in construction purposes. Radium equivalent activity from soil samples has been found within the range of 115–196 Bq/kg. Annual effective dose for indoor and outdoor environment has been found below the safe limit of 1 mSv/y for inhabitants. Scintillation based radon and thoron monitor have been utilized for measurement of radon and thoron exhalation rates. A positive correlation is observed between 238 U concentration and 222 Rn mass exhalation rates and also for 232 Th concentration and 220 Rn surface exhalation rates.
