It was found that in areas distant from an operating NPP the 14C concentration is characterized by values of 105-108 pMC. In the area of the Ignalina plant rather high 14C contents of vegetation (up to 150 pMC), and water of the lake Drisvyaty (127-154 pMC) connected by canals with the Ignalina NPP were noted. Biocarbonates (shells of lake mollusks Anadonta cygnaea and Dreissena, eggs poultry fed) are also enriched in radiocarbon. The concentrations of 14C in plants sampled in 1994-1996 in Gomel region (Chernobyl zone) are similar to those from the Ignalina NPP region and show increased values (up to 130-140 pMC). On the other hand, an emission of the radiocarbon resulted from the Chernobyl accident was recorded in the biosphere, at its concentrations increased toward the plant. So, 14C values were about 200 pMC near Minsk (May-June, 1986) and reached 600-700 pMC near Gomel. These data permit a realistic estimate of the concentrations of the radiocarbon emission at the instant of the accident. The radioisotope is well preserved and its redistribution occurs mainly due to biochemical processes. This is well shown by the radiocarbon distributions in a profile of the soil boggy medium.
