4.12 COMPARISON OF HEMATOLOGICALFINDINGS IN CHILDREN AND ADULTS, RONGELAP GROUP
It is seen from Tables 4.2 to 4.4 and Figs. 4.1, 4.2, and 4.4 that differences in the degree
of depression of cellular elements werepresent between children and adults. In Table 4.9, the
mean values of the neutrophile, lymphocyte and platelet counts at time of peak depression for
each element are given in terms of absolute count and per cent of appropriate contro] value
(mean platelet counts were calculated for the iess than 5 and greater than 5 age groups for this .
comparison).

of the lymphocyte count. These differences can be most easily described at the time of peak
depression. Expressed as per cent of control, all elements were affected more markedly in the
younger age group. These results would indicate that children are more sensitive to radiation,
or that other biological or physical factors resulted in a relatively greater effect.

An estimation of the severity of radiation damage incurred can be attempted by comparing
