[Aerial contamination of agroecosystems following the accident at the Chernobyl Nuclear plant].
The regularities of the aerial contamination of agricultural ecosystems are described in the early period after the Chernobyl NPP accident. The aerial contamination is shown to be caused by the development of the above-ground biomass of plants and fallout characteristics. A specific coefficient of primary retention varied between 0.46 and 1.2 m2 kg-1 for 137Cs. The first half-life period varies from 9.7 to 13.4 days. The second period varies from 46.2 to 52.2 days. It has been found that parameters of aerial contamination from the Chernobyl accident well correlate with the results of observation in the period of global fallout.
