Abstract
Peculiarities of the secondary wind uplift of radioactive aerosols in the ground layer of the atmosphere within the potential contamination zone of the former uranium production of the Prydniprovsk Chemical Plant were investigated; long-term dynamics of the wind regime at the “Kamyanske” weather station were analyzed. 9 models of secondary wind upwelling of aerosols were studied. Days with maximum wind speeds were selected for the modern period. Pollution of the ground layer of the atmosphere in the area around the plant was simulated for these days.
It was investigated that the coefficient of wind uplift of impurities in the ground layer depends on the wind speed, and the pattern of concentration field itself also depends on the direction of the wind and includes its other features for field calculation - the dispersed composition of the soil, dry and wet deposition rates, meteorological parameters etc. For different study areas, it is necessary to take into account not only meteorological conditions, but also the specifics of the source of pollution.
