X-irradiation of mice in early fetal period influences dose-dependently sex ratio of offspring until weaning.
Fractionated X-irradiation of mouse fetuses on gestation days 11-13 resulted in a significantly increased postnatal mortality of female litters. This occurred only at 3 x 110 rad, which was the threshold for the formation of typical neuroepithelial, rosette-like malformations.
