The knowledge of the behaviour of radioactive aerosol particles in the uranium mine atmosphere is very important due to the evaluation of the effective dose for uranium miners. During the research of the project SUJ200402-'Study of behaviour of natural long-lived radionuclides in the mine atmosphere', several measurement campaigns were performed in the last active Central Europe uranium mine Rozna I. The main purpose of this paper is characterisation the radionuclides which creating the main part of the airborne radioactivity in the uranium mine atmosphere. The present paper introduces results of the measurements of airborne radioactivity in stopes of the uranium mine Rozna I. The measurements were performed at the 21st floor at a depth of similar to 1100 m under the ground. In addition to the concentration of (222)Rn, its progenies, long-lived radionuclides and also the concentration of aerosol particles were measured.
