on the exposed population only. The histories were
taken by one of the Marshallese doctors. Complete physical examinations were done, butspecial
examinations, suchas slit-lamp studiesof the lens
and anthropometric measurements on thechildren {except for height and weight), were not
made. One hematological examination wascarried out on the exposed population which included WBC byelectronic 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°°.

surveys will generally be reported together.
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 unexposed. A census was not taken in 1960, but the
numberof people appeared to be aboutthe same.
Table 2 shows the percentage distribution in the
population for the Rongelap exposed and unex-
