Abstract

Based on multiyear monitoring observations, dynamics of 137Сs intake into the main tissues and organs of aboveground phytomass of Scots pine (Pinus sylvestris L.) during 30 years from the Chornobyl accident was determined as well peculiarities of their radioactive contamination. Empirical (observations), radioecological and statistical methods were used. It was found that for the wood increase of values of transfer factor was observed between 1991 and 2002 yrs with the further monotonous decrease of this value up to 2020; in internal bark, 1-year shoots, 2-year shoots, 1-year needles, 2-year needles, twigs thick and twigs thin multiyear dynamics was similar – an increase of values of transfer factor in the period of 1991 - 2002 yrs with further decrease of it up to 2020. At external bark, monotonous decrease of values of transfer factor was found during the whole observation period 1991 - 2020.
