The results of the retrospective global radioactive contamination mapping of the Enisey-river catchment are presented. The maps of spatial ,J7 Cs distributions of 1964, 1974, 1986, 2000 are compiled using the geo- information technologies in the Institute of Global Climate and Ecology. The territory of mapping is 26 km2. The mapping is done from the airbome-gamma-spectrum data obtained at the beginning of 1960, of 1970 and 1990. In 2000 the global levels of IJ7 Cs are 0.4-3 kBq/mJ. A small contribution of Chernobyl deposition can be registered on the maps built later 1986 (0.02-0.15 kBq/m:). The levels of 2.5-3 kBq/m1 in the region of Severo-Eniseyski and Teya localities can be estimated as the tail part of the eastern Chernobyl partem. The present levels of 2.59-122 kBqVm2 are observed on the Enissey valley at distances of 0-1700 km from Krasnoyarsk-26. The parameters of runoff and soil erosion are estimated using the cartographic information, provided by the Laboratory of River Processes and Soil Erosion of the Moscow State University. A part of 137 Cs, accumulated in the Enisey-valley from early 1960 to 2000 with the transport of soil material from interfluve of all Enisey tributaries, will be estimated using a balance model of soil erosion. The contribution of IJT Cs from the catchment to the valley is estimated with respect to total l37 Cs deposited in the valley.
