Radon in houses and soil of Croatia

Long-term indoor radon measurements in thousand Croatian homes, randomly selected, were performed by the LR-115 track etch detectors during a year 2003/2004. The obtained values of arithmetic means of radon concentrations in 20 Croatian counties were in range from 33 to 198 Bq/m3, while the arithmetic and geometric means for Croatia were 68 and 50 Bq/m3, respectively. Indoor radon concentrations follow log-normal distribution and the percentage of dwellings with concentrations above 400 Bq/m3 was 1.8 %. Radon concentrations in soil gas, at depth of 0.8 m, were measured by AlphaGUARD measuring system. Association between levels of indoor and soil radon was investigated.
