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 shock and was sent to the Memorial Hospital at Mayjuro, where her Fallopian tubes weretied. children of (1948-50) (1960) 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, and in the unexposed comparison population 77 adults and 86 children. lations, the birth rate for 1960 was calculated on Congenital Anomalies INTERVAL MEDICAL HISTORY 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.
