Thyroidal uptake and retention of $sup 131$I by pregnant and fetal guinea pigs

Technical Report ·
OSTI ID:4059688

Preliminary studies on thyroidal $sup 131$I concentration by fetal guinea pigs indicate a peak uptake approximately 7 times that of the maternal gland, with an effective half-life of less than 2 days. The resultant dose was estimated to be 37 rads for the maternal gland and from 60 to 81 rads for the fetal gland per microcurie administered. From 1 to 11 days after maternal injection of $sup 131$I, amniotic fluid contained more $sup 131$I per liter than did fetal blood which in turn had a greater concentration than did maternal blood.
