kinetic of absorption ~137Cs by pea plants and possibility of its modification with gamma-irradiation

摘要

Kinetic of ~137Cs absorption by seedlings of pea and possibility of alteration of the qualitative and quantitative characteristics of this process have been investigated. It is demonstrated, that gammairradiation of pea seeds lead to significant alterations not only of cation exchange capacity of biomass of intact seedling and cell walls, but first and second phase of kinetic curve of absorption and type of concentration curve. It suggest, that cation exchange capacity is one of main factors, which is determinated by primary intercompartmental distribution of ~137Cs as nonbiogenous mineral element.
