parable to that in published data (2.10), with
the exception of the platelets, on which previous
comparable data were not available.
Total leukocyte, neutrophile, lymphocyte,
monocyte, platelet and eosinophile counts for
the several exposure groups are given by day,
by sex and age in Tables 4.2 to 4.5. The total
white count, neutrophile, Ivmphoctyte and
platelet counts at the times of maximum depression (averaged over the time during which
counts were consistently the lowest) are shown
in Tables 4.6 and 4.7 for each individual in
(rroups Land TT respectively. Hematocrits for
wl exposure groups are shown in Table 4.8.
Hematological tindings as a function of time
and age are shown also in Figures 4.1 to 4.5.
The cumulative distribution curves for the
Various eXpesure groups, using the average of
counts obtained over the period of maximum
depression (days 39 to 41 for leukocytes; days
“6 to 40 for platelets) are shown in Figures 4.9
to 4.12." In the figures emphasis is placed on
the separate blood elements rather than on the
total leukocyte count, since the component elements have distinct and different time trends
after irradiation.
*In Grroup EV the cumulative distribucion curve for
platelet count< only is presented since hematological
determinations in thin group were net made during the
ote G1 day pertod, timed for leukocyte comparisons

The absolute neutrophile count of both the
younger and older age groups fell during the

Following the depression of the total neutrophile count during the znd week, the values
were unstable until the oth week.
At this time
the beginning of a second drop (p<cU.0)) was
noted for both age proups, and a low value of
