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 [0-year surveys
and can be readily seen in the accumuiative detnbution curves (Figures 23 and 35).
Bone marrow examinations oia few individual
at 9 and 10 years post exposure showed a reduced
myeloid-erythroid ratio with slight increase of immature red and white cells in some cases. There
has been noindication that these findings have
impaired the genera) health or response to disease
in the exposed people.
due to malignancies. Neither of these could be
ascribed reasonably to radiation exposure. The
somewhathigher 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 - an in
the Marshallese as a whole, but not significantly
so. Evaluation ofeffects of exposure on longevity
in this group must await furure findings.
AGING
No specific aging studies were carried out during the past two surveys, but attempts were made
during several previous surveys to put on a quantitauve basis various cntena of aging (skin elastic-
ity, skin looseness, hand strength, blood pressure,
artericeclerosis, accommodation and arcus senilis
of the eyes, greyness of hair, degree of baldness,
etc.). No detectable radiation-induced aging effects have been noted. Aging scores evaluated at 6
