4038 So June 1, 1965 PRELIMINARY STATEMENT OF MEDICAL FINDINGS IN THE 1965 SURVEY OF THE RONGELAP PEOPLE (11 YEARS) AFTER EXPOSURE TO FALLOUT RADIATION) The eleventh annual medical survey of the 76 exposed people and 200 unexposed people of Rongelap Island was completed in March of 1965. The health of both the exposed and ‘unexposed people on the Island is generally good, and the nutrition in both groups is satisfactory. Nodules of the thyroid gland were detected in three additional exposed people: two cases in boys 12 and 17 years of age and the other in an adult woman age 41. These nodules appear grossly similar to the nodules found in three teenage girls in 1964. Following surgical treatment, these latter nodules were found not to be malignant. The three new cases are being brought to Brookhaven National Laboratory for further examination and treatment in June, 1965. No malignancies have been detected in the exposed group which could be related to radiation exposure. No cases of leukemia have been detected, A few people show slight scars, and some have developed moles in the sites of their previous "beta burns", but with no signs of skin cancer, DOE ARCHIVES Mortality and birth rates have been about the same in the exposed as compared to the unexposed group. No increase in incidence of miscarriages and stillbirths in the exposed women has been noted since 1958. Evaluation of growth and development data for children has not been completed, so that | no additional statement can be made at this time in regard to the previously noted slight retardation of growth in boys exposed at less than five years of age. ~ .
