In this study, the authors discussed the situation in the Czech Republic regarding past and present uranium mining activities with emphasis on the evaluation of the exposure of underground miners in the Rozna Uranium Mine, which is currently the only active mine in the country and practically in the entire European Union. The total ED has been summarised taking into account all three major components, namely radon short-lived decay products, long-lived alpha emitters in ore dust and penetrating external gamma radiation. The average and maximum values of the ED as well as the collective ED of underground miners are also presented. The purpose of the paper is to document the miners’ exposures during a period of 6 years in a uranium mine where conditions including the ore grade and methods of mining showed recently some changes that may affect the individual components of the total ED.
