Abstract: © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Measurements of radon activity concentrations have been conducted in public kindergartens, primary, and secondary schools in Kragujevac City. This study represents the first step towards radon mapping of Central Serbia. Passive discriminative radon/thoron detectors (so called UFO) were used for monitoring. The radon calibration coefficient of 0.026 (track/cm2)/(Bqm-3 day) was calculated by exposing the UFO detectors in a Rn chamber monitored by a RAD7 device. The Rn concentration was in the range of 27-145Bqm-3 in kindergartens and 25-86Bqm-3 in schools. The value of the arithmetic mean was 59.6Bqm-3 and the standard deviation was 25.6Bqm-3. The distribution of the results was well fitted by log-normal function. No significant correlation between measured activity concentrations and periods of building constructions was found.
