Abstract

On purpose to estimate accumulation of radionuclides in the trees it is necessary to evaluate the amounts of biomass and theirs variations of the plants during different time of plants growth, because the plants having different age accumulate radionuclides differently. The increase of biomass depends on corona and roots of the tree. By means of roots plants are supplied by nourishment from soil; corona takes part in the processes of fhyto-synthesis. Different amounts of biomass are accumulated by different kinds of woody plants. Considering accumulation of radionuclides in wooden ecosystems it is necessary to take in account dependence of accumulation radionuclides on the age of the tree. The main aim of this work is to examine dependence of collection of radionuclides on biomass of the tree.
