ously, this may be related to fallout exposure of the
eyes. There were also several cases of corneal pig-

*Standard error of estimate.
Routine physical examinations of adults revealed that the slight differences in incidence of
various diseases in the exposed group compared
with the control group could likely be explained
by the somewhat greater number of older people
in the exposed group.
An ophthalmological survey revealed a slight
increase in the incidence of pterygia and pinguec-
ulae in the exposed group. As reported previ-
mentation which may have been related to fallout
exposure. There was no evidence in the exposed
people of retinal burns which might have resulted
from observation of the fireball at the time of the
accident in 1954.
A cancer detection survey was done which in-
cluded, in addition to thorough physical examinations, pelvic examinations in mature women with
Papanicolaou staining of smears, rectal examinations in adults, and hematological studies for leukemia detection, which included the determina-
tion of alkaline phosphatase levels of leukocytes
and basophil counts of 4000 white cells. No cases
of malignancy or leukemia were detected.
Pediatric examinations revealed no marked differences in abnormalities between exposed and
unexposed children and no diseases that could be
related to radiation effects. Growth and develop-
ment studies, as previously reported, showed that
the boys exposed at an early age (<6 yr and partic-
ularly 12 to 18 months) were slightly shorter in
stature and weighedslightly less than the unexposed children of comparable age. No such differences were noted in the exposed compared with
the unexposedgirls. Skeletal age determined by
wrist roentgenography showed that both the boys
and the girls in the exposed group were slightly
retarded, the boys showing the greater deficit. The
greatest retardation was noted in 4 boys who had
been 16 to 17 months old at exposure. Male chil-
dren (but not female) born of exposed parents
(after the fallout) tended to be smaller in stature
at all ages than children of unexposed parents.
