Radon in soil gas and constructed geogenic radon potential in Croatia

Radon concentrations in soil gas in Croatia were measured from 2005-2013 with the AlphaGUARD and from 2013- with RM-2 measuring systems, while soil permeability was measured with the Radon-JOK device since 2015. Measurements of both parameters were performed at 412 locations, mostly in the vicinity of schools and kindergartens and the obtained average value of radon in soil gas was 48 kBq m-3 with standard deviation of 52 kBq m-3. It is important to emphasize that there are areas with radon concentrations up to 550 kBq m3 . Geogenic radon potential (GRP) has been constructed by “Neznal approach” and a new subclassification with 7 classes (1- very low, 2 – low, 3 – medium lower, 4 – medium higher, 5 – high, 6 – very high, 7 – extremely high) is being introduced. The obtained average GRP of 28 ± 29 (“Neznal equation”) or 3.30 ± 0.96 (classes) classifies the soil of Croatia into soil of medium GRP.
