The analysis of changes in the Cs aggregated transfer factors (T) to the milk of farm animals in the southwestern districts of Bryansk region from 1986 to 2014 is presented. Several time intervals with different patterns of T half-lives were identified. The first half-life, calculated for 1987—1992, was 0.76 years. Since 1996, the reduction of Cs transfer factors to milk slowed significantly and became inhomogeneous. Differences in the dynamics of Cs aggregated transfer factors to milk were noted in zones with different Cs deposition densities.
Fesenko et al. (2025) studied this question.
