Abstract

A study of indoor radon in Krusevo has been carried out. Krusevo was selected for the study primarily because of its underlying geology which is known to be predominantly granite, with expected higher 226Ra concentration. Two sets measurements of the indoor radon concentration were performed, whereas: 8 houses were examined for the first (data from the National survey 2008-2009) and 11 houses for the second set of measurements (2010). The results showed that six of the examined houses revealed radon concentrations greater than the National action level of 400 Bq m-3, established for indoor radon concentration, 2 examined houses revealed concentrations between 200 and 400 Bq m-3, whereas 11 showed concentrations below 200 Bq m-3. In order to allocate the possible sources of the indoor radon, further studies were also carried out, including gamma spectrometry measurements of four soil samples, for determining specific activity of 40K, 226Ra and 232Th. Dose estimates based on measurements made in this study showed that the indoor radon may represent, in the longer term, significant health risk to some people who reside in houses with elevated indoor radon concentration.
