The 16 people in the Ailingnae population that were examined during was of interest that the platelet counts for all age groups averaged considerably higher in the Ctirik these two years showed blood counts similar to those of the higher dose Rongeiap group. The 10year platelet counts in the Ailingnae women were considerably higher than the previous counts; the reason for this is not apparent. The blood data on this group of people are summarized in Tables 18 and 19 and Appendix 2. Utirik Population. The people of Utirik Atoll who had been cxposed to a very low dose of radiation (an estimated 14 rads of whole-body gamma radiation) had leukocyte, neutrophil, and lymphocyte counts of about the samelevels as seen in the unexposed comparison population of Rongelap (Table 18 and Appendices 3 and 4). However,it people than in the Rongelap unexposed population. The explanation for this is not apparent. The eryth- rocytes, hemoglobin, and hematocrit levels were about the same as in the unexposed Rongelap people. Children of Exposed Parents. Blood courts of children of exposed parents compared with those of the children of parents in the comparison population showed no significant differences. These data are tabulated in Tables [8 and 19 and Ap pendices 4 and 5. During the 7th and &th-year surveys these children had shown slightly lower levels of leukocytes and plateiets compared with children of unexposed parents. This differenceis not apparent at this time. 49
