Comments on Hematological Data

The 1961 leukocyte and red blood countsremained slightly below the 1959 levels in the population at large, while the platelets were at about
the samelevel. Such fluctuations have been noted
before and have not been explained. The exposed
group continued to show slight depression ofcer-

tain blood elements compared with the unexposed
group. Though the meanlevels were only slightly
below those of the controls, more pronounced
differences were brought out by comparison of sex
and age groups. Thus, it appeared that the exposed male children (age 7 to 15 years) and the
exposed older people of both sexes (age >40)
showed lowerlevels, particularly of neutrophils

and platelets, than did the other age-sex groups

(see Figure 35). It is interesting that these blood
