in good health with no apparent nutritional deficiencies,
of cancer or leukemia was detected,
No evidence
Slight retardation of growth and
development was again noted in some of the exposed children, particu-
larly boys who were exposed at less than six years of age.
Thyroid
nodules were found in three exposed girls; these are being further
evaluated,
There were no illnesses that could be directly related to
radiation exposure,
Healed fallout burns of the skin, present in a
number of people, showed no indication of ulceration or malignancy,
though further pigmented changes such as nevus-like moles were noted,
Analysis of blood counts must be awaited to see if the slight depression
of blood counts previously noted still persists.
Measurements of body
burden of internally deposited radioisotopes will be estimated from
urine samples obtained from the people.
It is planned that equipment
will be brought to Rongelap in 1965 to report direct body measurement of
internally deposited radioisotopes.
Examinations of Rongelap people and Japanese fishermen exposed to
| fallout showed that similar effects of fallout exposure had occurred in
5
' both groups and that the doses of radiation received by the Rongelap
‘ people were generally about the same as received by the fishermen,
Similar types of fallout burns of the skin were observed.
