Abstract

Indoor radon and thoron measurements in dwellings of Pathsala area of Bajali sub-Division have been carried out using LR-115 (type II) detectors in plastic twin chamber dosimeter cups (BARC type). The estimated indoor radon levels varied from 89.51 to 125.41 Bq.m−3 with a mean value 103.7 Bq.m−3. The thoron levels were found to vary from 36.0 to 55.03 Bq.m−3 with a mean value 37.87 Bq.m−3. The estimated inhalation dose for the inhabitants varied from 0.47 to 0.59 μSv.h−1 with a mean value 0.53 μSv.h−1.
