title: [Estimation of the involvement of 137Cs in biological cycle of pine biogeocenoses].
abstract: The estimation of accumulated radionuclides in the biological cycle was carried out on the basis of long-term studies of distribution of 137Cs in the aboveground phytomass of pine plantations. The two main stages which differ from each other in the intensity of the involvement of 137Cs have been defined: the most intensive accumulation of 137Cs in the phytomass of pine plantations in the early 1990s (up to 2.3% of the total activity in biogeocoenose) and quasi-equilibrium distribution of 137Cs in the ecosystem since the 2000s when phytomass has received about 1% of the total activity. The accumulation of the radionuclide during the current year mainly occurs due to its transfer through the needles.
