~6Results of examinations, The people of Rongelap and Utirik were found to be generally in good health, Their nutrition was reasonably good with no apparent deficiencies of vitamins or other dietary components, Fewer fungus and other skin infections were noted and this was thought to be related to the generally improved hygienic and sanitary conditions on the Islands, Adult examinations, In Table I (next page) are listed the incidences of various physical abnormalities in the adult populations of Rongelap and Utirik examined, The general incidence of various abnormalities in the exposed people did not appear to be significantly different from that in the unexposed people. The incidence of moderate to severe arteriosclerosis was somewhat greater in the exposed Rongelap group, but this might be accounted for by the fact that there was a larger number of older people in this group. No malignant lesions were detected in either the exposed or unexposed groups, Pelvic examinations revealed the usual large number of cervical erosions, lacerations, etc, inthe Marshallese women, Rectal examinations revealed prostatic hypertrophy in several older men but with no evidence of malignancy, It was noted that there were fewer infections of the skin than previously observed, Pediatric examinations, A total of 212 children were examined, This number consisted of 25 children exposed on Rongelap, 32 children exposed on Utirik, 35 children born after the fallout to exposed parents, and 120 controls, The list of abnormal physical findings in the exposed and control groups of children have been summarized in Table II, page 8, Of particular interest was the develonment of a palpable nodule in the thyroid gland of a 12 year old girl (#17), who had been exposed to fallout irradiation on Rongelap, has been planned, Histological study of the nodule During the poliomyelitis epidemic on these atolls, in the study developed symptoms and signs suggestive of poliomyelitis, 23 children Residual weakness of muscle groups was evident in 13 of these children at the time of the examinations,
