years. There were 20 such women in the exposed
group and 29 in the unexposed group(not included in either group were 4 unexposed women whose
spouses were exposed males). In the exposed group
7 babies were born, giving an average of 0.35
births per women, and in the unexposed group11
babies, giving about the same average (0.38). The
deliveries were reported to be full term and normal, except that one unexposed women (No.867)
developed severe post-partum hemorrhage and

Of the 334 Rongelap people, 267 were examined during the survey on Kwajalein, Majuro, and
Rongelap. In the exposed group 47 adults, 25
children (age < 20), 4 children exposed in utero,
and 28 children of exposed parents were examined,

Mortality
No deaths occurred during 1960 in the exposed
or comparison population except for two infant
deaths. The four deaths that had occurred in the
exposed group over the 7-year post-exposureperiod represent a rate of 7.1 per 1000 population,
which is about the same asthat reported for the
Marshall Islands as a whole (6.8 per 1000). The
unexposed population on Rongelap Island has
One baby, born of unexposed parents, was
anencephalic and died several days after birth.
Thefirst instance of congenital anomaly in a child
of exposed parents was reported during the past
year. This was a congenital heart defect in a baby
born of an exposed mother (No. 75) but unexposed father. The baby died at four monthsof age.
Unfortunately the diagnosis was not confirmed by
autopsy. A low incidence of patent ductusarteri-
