measurememts, indicate that fractionation of radionuclides was prominent in the fall-out particles. Measured R values for Ba/sup 140/ and Sr/sup 89/ based on Mo/sup 99/ were over an order of magnitude lower in the altered particles The fissions/gram values of altered particles averaged the two classes of particles taken from H + 50 to H + 10,000 hr showed marked t dissimilarities.

Journal Announcement: NSA14 Document Type: Journal Article Language: English A medical survey of the Marshallese people in March 1959, five years after exposure to fallout radiation, showed that the people had recovered from the acute effects of their radiation exposure and appeared to be generally in good health. No illnesses or diseases were found that could be directly associated with acute radiation effects. One case of cancer and three deaths had occurred, but with no direct relation to radiation effects. Fertility did not appear to be affected. The incidence of miscarriages and stillbirths appeared to be somewhat higher than in the unexposed Marshallese, but a deficiency of vital statistics precluded definite conclusions as to whether or not this is a radiation effect. Suggestive evidence of slight lag in growth and development of exposed children noted previously was re-evaluated on the basis of better age data obtained during the latest survey. Blood platelet levels were within the normal range but somewhat below that for the unexposed population. Only 11 cases showed residual changes in the skin from beta burns. None ~howed any evidence of cancerous change. Possible late effects of radiation such as shortening of life span, premature aging, leukemia and malignancies, increased incidence of increased incidence of degenerative diseases, opacities of the lens of the eyes, and genetic changes were not detected. The original body burdens of internally absorbed fission products appeared to be too low to have produced any acute or long-term effects. The return of the people to the slightly contaminated island of Rongelap resulted in some increase in body burdens of Cs/sup 137/, However, Zn/sup 65/, and Sr/sup 90/. the levels were far below the accepted maximum permissibie limits, and it is not believed any detrimental effects will result.
