Radon concentrations in kindergartens of Osijek and Ljubljana


Indoor radon concentrations in the kidergartens of Osijek, Croatia, have been measured with α-scintillation cells, LR-115 nuclear track detectors, as well as a Radhome semiconductor detector. Average values of 50.2, 43.7 and 47 Bq m−3 were obtained, respectively. Under the worst conditions, the annual radon effective dose equivalent was 10 mSv y−1. Using bare and filtered LR-115 detectors, the average equilibrium factor was assessed as 0.36 indoors. Measurements of the γ-dose rate in the kindergartens did not show any significant correlation with the radon concentration. Indoor radon concentrations in the kindergartens of Ljubljana, Slovenia, measured by scintillation cells had an arithmetic mean and standard deviation of 228 and 143 Bq m−3, respectively.
