Abstract		Uranium mining and milling, in general, do not have a great impact on the enhancment of outdoor radon concentrations in the local environment. Therefore, inhalation of its daughters should not represent a serious radiation exposure for critical group. The "Zirovski vrh" uranium mine in Slovena seems to be an exception. The topographical and climatological characteristics of the mine and mill environment do not allow radon to disperse immediately: air masses could be channelled quite a long distance along the populated valley and enhanced radon concentrations could be measured up to 3-5 km distance from the mine and mill emmission points. The main attention of the paper is focused on results of outdoor radon determinations over the last five years. The range of measured values at different locations, mean values and the contribution of teh mine to levels of radon are discussed.
