Identification and mapping of radon-prone areas in Croatia— preliminary results for Lika-Senj and the southern part of Karlovac Counties

Long-term indoor radon measurements performed by LR 115 track etched detectors in Croatian homes during 2003–04 showed that the arithmetic means of radon concentrations in Lika-Senj and the southern part of Karlovac counties were three times higher (198 Bq m^−3) than in houses at national level (68 Bq m^−3). Recently, indoor radon measurements in randomly selected houses were investigated. The obtained values in these new measurements have confirmed the values obtained 10 y ago (the average radon value in 225 investigated houses in this area is 223 Bq m^−3). Radon concentrations in soil gas were measured in September and October 2012 and 2013 with the AlphaGUARD measuring system. Areas with both elevated indoor radon levels and radon in soil gas were identified (some micro locations in Korenica, Ličko Lešće, Generalski Stol, Slunj and Ogulin) and visually presented in the form of maps using the inverse distance weighting approach.
