MATHEMATICAL MODELLING OF RADIOACTIVE NUCLIDE MIGRATION IN SOIL – VEGETATIVE COMPLEXES OF ORENBURZHYE ^{[№ 9 ' 2005]}
Research of migration of elements on a soil structure is one of the important approaches to studying of anthropogenous influence on vegetation. Radioactive nuclide migration on a ground structure occurs due to moving of soil particles, which form its structure, due to movement of the soil moisture, containing soluble and colloidal their forms. Sorption of heavy metals is carried out due to two processes fast – exchange and slow not exchange.
