Summarizing Discussion
MORTALITY
HEALTH STATUS
over the 10-year period. Of these, two deaths were
due to malignancies. Neither of these could be
ascribed reasonably to radiation exposure. The
Medical evaluation of the health status of the
exposed Rongelap people over the years since the
accident has revealed about the same incidence of
illness and disease as in the unexposed population
with the exceptions noted below. General health
and nutrition has continued to be satisfactory and
comparable to that of the unexposed comparison
population. Annual hematological follow-up
studies have revealed that the levels of white
cells and platelets of the peripheral blood in the
exposed group have never quite reached the levels
of the unexposed comparison population. This was
again demonstrated in the 9 and 10-year surveys
and can be readily seen in the accumulative distri-
There were 10 deaths in the exposed population
somewhat higher death rate in the exposed group
is partly offset by the higher proportion of older
people, those >65 years of age being 20% in the
exposed group and only 7% in the unexposed
group. This mortality rate is also higher than in
the Marshallese as a whole, but notsignificantly
so. Evaluation ofeffects of exposure on longevity
in this group must await future findings.
