with marked growth retardation (Nos. 3 and 5).
T, levels before surgery were lower in subjects exposed in childhood than in unexposed controls.
Subjects exposed as adults who developed either
benign or malignant thyroid lesions did not show
notable impairment of thyroid function. The
serum iodine levels of exposed and unexposed
people for the past 15 years are given in Appendix 8.
In 1965, the rates of urine and thyroid accumu-

lation of 132] were measured over a 4-hr period in

21 Rongelap subjects, of whom 9 were unexposed
and 12 were exposed as adults.!8 The data are
summarized in Table 26. Compared with North

American normal values obtained in 196518

(urine, Ag; 2; thyroid, Ag, 2=1; thyroid fraction

0.33), both the exposed and unexposed Mar-

shallese showed slow urine and thyroid transfer

rates of extrathyroid iodide but a high thvroidfraction. Similar studies done in 1972 on 2 Rongelapese without detectable thyroid abnurmalities.
