age group, males, were consistently higher than those of
the adult group in absolute counts but consistently lower
as percentage of control.
There was no evidence of hemorrhage into tissues,
even though in 11 individuals platelet count levels
reached between 35,000 and 65,000 per cubic milli-
meter. Two women menstruated when their platelet
counts were 150,000 and 130,000 per cubic millimeter
respectively. Both experienced excessive menstrual
bleeding, insufficient to cause them concern, which subsided withouttherapy.

Fig. 2.—Mean platelet changes in highest exposure group (64 people).
Six months after the accident, blood cell counts
showed only slight increase over previous ones during
the last week (10th) of the initial observation period and
were still below control levels. Follow-up studies at one
year after the accident showedthat the neutrophil counts
of the exposed individuals were back to the controllevel;
however, the lymphocytes, monocytes, eosinophils, and
platelets werestill below control levels, though they were
