Abstract

The main contribution to the population exposure is due to radon and thoron progenies and not radon and thoron itself. Nevertheless, due to the simplicity and cost effectiveness of radon/thoron measurements compared to the measurements of their progenies, effective doses are usually estimated from the measured Rn/Tn concentrations with the assumed value of equilibrium factor. In this paper, an overview of direct measurements of radon and thoron progenies is some parts of Balkans performed within the framework of large international collaboration is given. In this joint venture, long-term measurements were carried out in dwellings and schools using direct radon progeny sensors/direct thoron progeny sensors (DRPSs/DTPSs). Large scale Rn/Tn progeny survey was performed using 321 DRPSs/DTPSs detectors in the period from 2011 till 2013 encompassing some parts of Serbia: 125 dwellings in the region of Soko Banja (Southern Serbia), 48 dwellings in Kosovo, 44 schools in FYR of Macedonia and 37 dwelling and 25 schools in Republic of Srpska. The detectors were deployed from 3 months up to one year, since long term measurements are essential for assessing inhalation doses to the public. In case where possible seasonal variations were discussed as well. Effective doses were estimated from measured equilibrium equivalent radon and thoron concentrations (EERC and EETC) considering different occupancy factors for inhabitants and pupils.
