The histories were taken by one of the Marshallese doctors. Complete physical examinations were done, but special examinations, such as slit-lamp studiesof the lens and anthropometric measurements on the children (except for height and weight), were not made. One hematological examination was carned out on the exposed population which included WBC by electronic counting technique (Coulter), differential smears, smears for alkaline phosphatase staining, and basophil counts. About thirty 24-hr urine samples were collected from exposed and unexposed people for radiochemical analysis to determine body burdensof Sr*°. Marshall Islands (1948-50) . 33.8% US.

INTERVAL MEDICAL HISTORY The census of Rongelap as of 1959 was 308 people, of whom 82 had been exposed, 20 were children born of the exposed, and 206 were unex- posed. A census was not taken in 1960, but the numberof people appeared to be about the same. Table 2 shows the percentage distribution in the population for the Rongelap exposed and unex- — ey ee ee
