Radioactive Iodine Concentration in the Fetal Human Thyroid Gland from Fall-out

>A study was made of the occurrence of I¹³¹ in human fetal thyroid glands apparently resulting from I¹³¹ received by the mother from nuclear weapons testing or other types of population contamination. Radioactivity compatible with I¹³¹ was found in the human fetal thyroid gland. The maximum concentration of I¹³¹ was 265 mu mu c per gram of fetal thyroid tissue, 29.1 mu mu c per gram of adult hog thyroid tissue and 22.9 mu mu c per gram of adult thyroid tissue. The highest activity found on a reagent blank was 10.0 mu mu c. The calculated maximum total radiation delivered to any human fetal thyroid gland was 0.47 rads. The average total dose was 0.05 rads. Extrapolations from data on animals suggest that it is unlikely that this quantity of radiation would produce hypothyroidism or carcinoma of the thyroid gland. (auth)
