Dynamics of 137Cs Concentration in Fodder in the Long-Term after the Chernobyl Accident

The data on the dynamics of the 137Cs transfer coefficients (Tf) for fodder in the long term after the Chernobyl accident (2008–2020) are presented. It is shown that the ecological half-lives of transfer coefficients varied from 7.8 to 28.9 years. The obtained estimates are consistent with the second half-life periods of transfer coefficients estimated based on data for the first eight years after the Chernobyl accident. The peculiarities of the dynamics of Tf to fodder were in good agreement with the scales of remedial actions carried out in the contaminated territories.
