Comments on Hematological Data The 1961 leukocyte and red blood countsremainedslightly 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 showslight depression ofcer- 32 36 L 40 44 48 HEMATOCRIT : 52 Figure 50.

Though the meanlevels were only slightly below those of the controls, more pronounced differences were brought out by comparison ofsex 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) showedlower levels, particularly of neutrophils andplatelets, than did the other age-sex groups (see Figure 35). It is interesting that these blood
