N2 - The radionuclide composition of the atmospheric precipitations (rain and snow) fell out on the territory of the South of the Western Siberia in 2016-2017 was studied. It is shown that, the maximum of deposition of Be and Pb were observed in a foothill zone (618 and 171 Bq/m), the minimum in the Alpine zone (104 and 27 Bq/m), for the forest-steppe zone these values are 237-340 Bq/m and 73-93 Bq/m. Deposition density of Cs in comparison with Pb and Be is small and does not exceed 1 Bq/m. Average values of total specific activities of Pb and Be in rain waters are 242 and 2434 mBq/l, in the snowmelt 506 and 1611 mBq/l. Be/Pb activity ratio in rain waters more than three times higher, than in snowmelt: 10,1 to 3,2. The highest values of Be/Pb activity ratios are observed in the finest fraction (<0.45 μm) of the suspended matter: 19 in rain and 10 in snowmelt waters.
