Even before the developmentof thyroid nodules
was noted, the evaluation of thyroid status of exposed individuals received considerable attention,
>
since it was recognized that the slight growthretardation noted in some of the children might be
related to radiation effects on that gland. However, on the basis of physical examinations and
serum PBI and cholesterol determinations each individual examinedat that time was believed to be
euthyroid. It soon became apparentthat the average serum protein boundiodine in the Marshallese
of both Rongelap and Utirik was higher than
~
dose from the various iodine isotopesto the child’s
gland was about 1000 rads, with a range of 700 to
1400 rads. The glands received an extra 175 rads
from external gammaradiation.
~
*Placed in this category because of nearly complete atrophy of the thyroid gland.
