Abstract:

The model of reconstruction of polydisperse admixture fallout fields along the trace axis of instantaneous source was proposed. To describe a process of aerosol transfer in the atmosphere, analytical solutions of semi-empirical equation of turbulent diffusion were applied. Admixture fractional composition within a sedimentation velocity in the source is specified by a double Gamma-distribution. Approbation of a developed model was done on the monitoring data of the accident at radiochemical plant in Tomsk-7 on April 1993.
