JNIH-ABCC life span study of children born to atomic bomb survivors. Report II. Mortality in children of atomic bomb survivors and controls

Technical Report:

Abstract

The study was updated so that the average interval between birth and verification of death or survival is now 17 years. The mortality experience is based on 18,946 children liveborn to parents proximally exposed (dose 117 rem); 16,516 children born to distally exposed parents (essentially no dose); and 17,263 children born to parents not in Hiroshima or Nagasaki at the time of the bombs. No clearly significant effect of parental exposure on child's survival can be demonstrated by contingency chi/sup 2/ or regression analysis. Based on regression, the minimal gametic doubling dose for mutations resulting in death during the first 17 years for liveborn infants conceived 0--13 years after parental exposure is 46 rem for fathers and 125 rem for mothers. Since the regression coefficients do not differ significantly from zero, it is preferable, in a situation where men and women are irradiated in equal numbers, to employ the average of the two estimates, namely 85 rem. The gametic doubling dose for chronic, low-level radiation is expected to be 3 to 4 times this value. (DLC)
