Atmospheric radon concentrations in dwellings in Slovenia, Yugoslavia.
About 120 homes in Slovenia, Yugoslavia, were selected in urban areas, in a uranium rain and mill region, around coal-fired plants and around a phosphate mill. Radon-222 in air was determined using alpha scintillation cells and the gamma dose rate measured with thermoluminescent dosimeters. The levels obtained were explained by differences in building materials and ventilation rates of homes, as well as by the influence of man-made radioactivity sources. The results show that in the same region radon concentration, expressed as geometric mean, can be up to eight times higher in winter than in the autumn (Pohorje) or nine times higher in one region relative to another (Zirovski vrh-Zasavje).
