Abstract
The paper presents the results of field survey, chemical-analytical and numerical analysis of data on processes of dust aerosols precipitations in the area of intensive influence Tomsk GRES-2 of emissions in winter periods from 2009 to 2012. In the model reconstruction of the field depositions monodisperse contaminants from a point source we interpret the observed data content in the snow solid residue of uranium, thorium, in the direction of the route of sampling. It is shown that the most significant deposition of contaminants occur near vicinity of tall pipes station comprising larger particle fractions.
