Studies on radon and thoron levels in few dwellings of Kabini River Basin, Karnataka State, India

Measurement of indoor radon, thoron and their equilibrium equivalent concentrations in different dwellings around Kabini river basin, Karnataka State, India was carried out using SSNTD based pin-hole dosimeters during 2017–2018. Indoor concentrations of radon and thoron are varied from 18.9 to 156.8...

More Information
Summary:Measurement of indoor radon, thoron and their equilibrium equivalent concentrations in different dwellings around Kabini river basin, Karnataka State, India was carried out using SSNTD based pin-hole dosimeters during 2017–2018. Indoor concentrations of radon and thoron are varied from 18.9 to 156.8 Bq m − 3 and 13.1 to 110.0 Bq m − 3 , respectively. The present study reveals that the annual effective dose received by the people of the study area is lesser than the recommended level 3–10 mSv y − 1 of the International Commission of Radiological Protection and is safe from the exposure of radon, thoron and their progenies.
