n the exposed population only. The histories were
tken by one of the Marshallese doctors. Com‘ete physical examinations were done,but special
xaminations, such as slit-lamp studies ofthe 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), diflerential 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 burdens of Sr”.

population for the Rongelap exposed and unex-
