following general trends were noted: (1) Both the
exposed and control Marshallese children tended
to be less mature skeletally at comparable chronological ages than the norms published by Greulich
and Pyle. (2) Boys tended to be consistently less
matureskeletally than girls at comparable chronologic ages. (3) Exposed children, both boys and

girls, tended to be less mature than control children. (4) When the children were grouped accord-
ing to age at exposure, the exposed comparedto
the control group of both boys and girls tended to
be less mature. Although these trends suggested
that the exposed children maybe inferiorin skeletal maturation to unexposed children, the differences did not reach thelevelofstatistical stgnificance. The retardation in skeletal development
was most prominentin the group of children exposed to fallout at ages 12 to 18 months. As expected, there was a high correlation between retardation in skeletal age and inferiority in statural
growth.
Of special interest was the group of children
now 8 years old who were exposedto fallout at
ages 12 to 18 months. The statural measurements
for these 5 children from 1958 through 1961 com-
