of levels of <(250,000 in 44%of the exposed group
(including Ailingnae) but in only 25%of the unexposed group.

showed generally lower levels in the exposed males
of age >15 and females of age >40 years. These
differences were not markedasin the case of some
of the other peripheral blood elements. Thescattergrams (Figures 47 and 48), cumulative percentage distribution curves (Figures +9 and 50) and
histogram (Figure 35) demonstrate this.

No very unusual morphological changes in
blood ceils were noted. A few bilobed lympho-
cytes were seen in differential smears of both ex-
posed and unexposed people, but no counts were
made. Price-Jones curves in the past have shown
a slight microcytic tendency ofthe red cells.
Ailingnae Blood Counts
Of the 17 Ailingnae people, 15 were available
for examination. The levels of peripheral blood elements in this group were generallyvery nearly
the sameas in the unexposed population, except
that the platelets were still somewhat belowthe
unexposed mean levels for most of the age and sex
groups (see Table 12 and Appendix 3).
