Abstract
The purpose of the present study is to assess dose received by individual tissues or organs of human beings from the exposure of indoor radon (Rn-222), thoron (Rn-220) and their progeny concentrations using single entry pinhole dosimeters and deposition based progeny sensors (DRPS/DTPS). The deployment of dosimeters were carried out in 75 dwellings across Hanumangarh district of Rajasthan, India. Annual and seasonal activity concentrations were monitored based on which dose distribution to various tissues and organs were assessed. The estimated average annual effective dose of the study area is 0.8 mSvy−1, which is lower than the ICRP recommended limit of 4 mSvy−1 (at work place) and 14 mSvy−1 (for residential buildings) (International Commission on Radiological Protection (ICRP) in Radiological protection against radon exposure, ICRP, Stockholm, 2018). Consequently, indoor radon may pose no health risk to the local population of the studied area.
