Thyroid glands of developing fetuses are highly susceptible to radiation damage following maternal assimilation of radioiodines from nuclear fission or from medical diagnostic or therapeutic administration. The facility with which radioiodine is transported across the placenta assures fetal exposure to maternal radioiodine; the initiation of thyroid function in the young prior to parturition results in thyroidal concentration of radioiodine. Work in this field by a number of workers is correlated. The onset of radioiodine concentration by fetal thyroid glands for a number of mammals is tabulated. Fetal/maternal ratios of thyroidal $sup 131$I concentration following (a) a single maternal administration and (b) chronic maternal exposure, are shown graphically for various mammals. (UK)
