This paper presents a method of predicting the total intake commitment of radioiodine by an average member of the human population after a single contamination of pastures has taken place. Equations for the radioiodine transfer to milk with time are presented for cows given twice-daily doses of radioiodine. These curves are then modified to account for intake of radioiodine by the cow, radioactive decay, residence time of the radioisotope on vegetation, time delay from production to consumption, and the volume of milk consumed by the average individual. This is then integrated to calculate total radioiodine intake commitment by the human population. Ratios have then been calculated by dividing the total intake of radioiodine from 0 to infinite time by the concentration of radioiodine in milk from day 1 to day 15. From a table of these ratios it is possible to predict the total radioiodine intake of an average individual knowing the level of radioiodine in a sample of milk and the time relation of that sample to the initial contamination of the pastures. This method makes it possible to estimate the radioiodine consumed by the human population without estimating the intake of radioiodine by the dairy cow.
