Abstract: Levels of ¹³⁷Cs accumulation by herbaceous plants on peat-bog soils lands of the Stare Selo settlement of Rokytne district of Rivne region were investigated 31 years after the Chernobyl accident. Data on terrestrial contamination density with ¹³⁷Cs and vertical distribution of ¹³⁷Cs in soil profiles are presented. ¹³⁷Cs accumulation coefficients and transfer factors from peat-bog soils to dominant species of herbaceous plants were determined. Differences of ¹³⁷Cs accumulation by herbaceous plants depending on the development stage and vegetative period were revealed. Forecast of milk contamination with ¹³⁷Cs was made under the application of meadow grasslands as the feed on the investigated territory of fodder lands.

Keywords: ¹³⁷Cs, accumulation coefficient, transfer factor, specific activity, peat-bog soils, Chernobyl accident.
