Of these, two deaths were due to malignancies. Neither of these could be ascribed reasonably to radiation exposure. The Medical evaluation of the health status of the exposed Rongelap people over the years since the accident has revealed about the same incidence of illness and disease as in the unexposed population with the exceptions noted below. General health and nutrition has continued to be satisfactory and comparable to that of the unexposed comparison population. Annual hematological follow-up studies have revealed that the levels of white cells and platelets of the peripheral blood in the exposed group have never quite reached the levels of the unexposed comparison population. This was again demonstrated in the 9 and 10-year surveys and can be readily seen in the accumulative distri- There were 10 deaths in the exposed population somewhat higher death rate in the exposed group is partly offset by the higher proportion of older people, those >65 years of age being 20% in the exposed group and only 7% in the unexposed group. This mortality rate is also higher than in the Marshallese as a whole, but notsignificantly so. Evaluation ofeffects of exposure on longevity in this group must await future findings. AGING mature red and white cells in some cases. There No specific aging studies were carried out during the past two surveys, but attempts were made during several previous surveys to put on a quantitative basis various criteria of aging (skin elasticity, skin looseness, hand strength, blood pressure, arteriosclerosis, accommodation and arcus senilis impaired the general health or response to disease in the exposed people. etc.). No detectable radiation-induced aging effects have been noted. Aging scores evaluated at 6 bution curves (Figures 23 and 35). Bone marrow examinationsof a few individuals at 9 and 10 years post exposure showed a reduced myeloid-erythroid ratio with slight increase of im- has been noindication that these findings have of the eyes, greyness of hair, degree of baldness,
