The exposure dose rates, the equivalent equilibrium volume activity of radon, and the activity of long-lived alpha-nuclides in the air of the uranium protoxide-oxide calcination shop were determined. Annual effective doses for workers were calculated. Through the use of nuclear-based polietilentereftalata and chemical filters, the disperse composition of particles in the air was studied. The effectiveness of filters in sampling was evaluated for the uranium content. The kinetics of distribution
