Abstract
The paper analyses the long-term dynamics of radionuclide distribution among the basic compartments of forest ecosystems under conditions of single-time aerial contamination. Forests are shown to be long-term sinks for radionuclides and serve as effective biogeochemical barriers to radionuclide migration. Radionuclide redistribution in the “soil-plant” system is characterised by three main stages of increasing duration and with different dominant processes. The dynamics of the biological availability of radionuclides is primarily determined by landscape conditions and the physico-chemical forms of the initial fallout. Biota dependent migration is the largest contributor to the geochemical cycle of radionuclides in forest landscapes, whereas water migration is practically insignificant.
