Cytogenetic Study of the Offspring of Atom Bomb Survivors

Abstract

EXTENSIVE studies of offspring conceived after the exposure of their parents to the atom bomb have revealed no increased frequency of stillbirths, neonatal deaths or gross malformations1. Furthermore, there has been no overall increase in the mortality rate in the F1 generation2, and initial impressions of an alteration in the sex ratio have not been substantiated3. These essentially negative findings suggest that no effects were produced, that the sample size was too small to allow detection of genetic effects, or that the indicators used were insufficiently sensitive.
