YEARS POST -EXPOSURE
Figure 2. Mean blood cell counts of the different exposure groups (age 5 years or more) expressed as percent of
control, beginning two years after exposure. Values for both sexes are grouped for neutrophils and lymphocytes.
Detailed annual observations on Utirik blood cell counts were not begun until 1973. Leukocyte differentials or
platelet counts were not obtained for six and five annual examinations, respectively, although for graphing
purposes the 100% line has not been broken at those years.
