The transfer factors of iodine isotopes from the daily diet to milk of the cows in the pasture period for different soil and landscape conditions of Ukraine were evaluated and analyzed. It was shown that the possible values of the considered coefficient of the transition is a random variable, which is satisfactorily described by the lognormal distribution law of probabilities. The resulting estimates of medians (GM = 0.046 ± 0.003) and the geometric standard deviation (GSD = 1.79) for possible iodine conversion coefficient of the daily diet in cow's milk were obtained. They refine the IAEA reference data for specific soil-landscape conditions of continental Ukraine and allow obtaining less conservative estimates when predicting the specific content of iodine isotopes in the milk of cows in the pasture period.
