Abstract: Results of the small-field experimental study of the dynamics of biological availability of freshly added standard radioactive solution of 137Cs in peat-bog soil are presented. The initial values of the 137Cs concentration ratios CR(t) and transfer factors TF(t), in the aboveground phytomass of natural meadow grass vegetation in peat-bog soils in the real soil-climatic conditions of Western Polissya were determined. Based on the results of the field and laboratory studies, the values of fast and slow periods of the ecological half-reduction (Tfe and Tse, respectively) of CR and TF of radioactive cesium in the studied soils were estimated. The model for prediction of the dynamics of CR and TF of radioactive cesium into natural meadow grass vegetation from peat-bog soils with its abnormal high biological availability was proposed.

Keywords: 137Cs, concentration ratio, transfer factor, dynamics, peat-bog soils, mathematical model.
