## Abstract

The paper presents the results of the studies of the levels of radon in the premises of 30 kindergartens and 36 schools of Tomsk and its region, which were conducted in 1989 to 2000. The volume activity of radon in the air of the premises was measured by using passive track detectors of gamma-radiation upon a long-term exposure of 1-3 months. In parallel with these measurements, statistical data required for a more accurate assessment of effective doses were collected. Analysis of the statistical processing of the data on the levels of radon has indicated that the arithmetic mean, geometric mean, and standard deviation are 60, 51, and 33 Bq/m3, respectively, for kindergartens and 50, 38, and 56 Bq/m3 for schools. The mean annual radiation doses obtained on inhalation exposure to radon-222 and its degradation products are 1.06 and 1.08 mZv for preschool and school children, respectively.
