Experiment was carried out in order to know the distribution of 131I in milk and the secretion into milk from lactating Holstein cows after a single intravenous administration. It was recognized that about 26% and 61% of dosed 131I was recovered during the 6 days following administration from milk of Holstein (A) and (B) respectively. About 2% and 20% of 131I were found in fat and protein fractions respectively and no regular variation was observed on the distribution pattern as a function of

From those considerations it was concluded that Glascock's assumption would be acceptable and consequently the composite system of ion exchange treatment and CCl4 extraction would be also acceptable as a rapid and convenient method for the determination of 131I in milk previously recommended by the authors.
