Abstract

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.
