Regularities of the pollution formation in the axial part of the East-Ural radioactive trace

Models for the assessment of regional pollution of the territory from a high-altitude aerosol source were constructed on the basis of solutions of the semi-empiric equation of turbulent diffusion. The models were tested using the observational data from the East-Ural radioactive trace, which was formed as a result of explosion of a reservoir with radioactive waste on PA Mayak in Chelyabinsk region in 1957. The possibility of prediction of pollution in the trace axial part using the obtained estimates of parameters is shown.
