on the exposed population only. The histories were
taken by one of the Marshallese doctors. Complete physical examinations were done, butspecial
examinations, such as slit-lamp studies of the lens
and anthropometric measurements on the children (except for height and weight), were not
made. One hematological examination was carried 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®°,
