To improve the effectiveness of responses to severe accident in the field of population and agricultural production before the accident, proposed to prevent collect and analyze cartographic, statistical, environmental and others. The information needed to predict and assess the radiological situation. The methodology of radio-ecological zoning of the territory contaminated with radioactive fallout, using GIS technology, which was based on landscape-basin principle. A model of the territory, taxonomic units which are elements of the landscape or objects of agricultural land use. The river pond is a primary objective of the existing structural unit of the territory. The main characteristics are the type of soil, the type of terrain and the type of underlying surface. The application model provides the coordination of spatial and temporal distribution of characteristics, coupled models of atmospheric diffusion and migration of radionuclides on the chain "soil - plants - animals - Products - man" and dosimetric models to determine countermeasures that may be necessary after the accident. To forecast the radiation environment on the track used by the accidental release of the authors developed a model of atmospheric transport of radionuclides, aeral and root of plant contamination.
Keywords: severe accident, radioecological model territory zoning, forecasting the radiation situation.
