Effects of stable iodide blocking of exposure to radioiodine. Progress report, November 1, 1974--October 31, 1975

Results are reported from studies on the influence of dietary iodine intake on the uptake of $sup 131$I by the thyroid gland of beagles. A model of iodine kinetics in normal dogs was developed that consists of separate subsystems for iodine, thyroxine, triiodothyronine, and the thyroid gland. The model demonstrates important differences in iodine metabolism and thyroid function between the dog and man. (CH)
