Description

Pregnant females and newborn rats were exposed to a gamma irradiation of 150 rads. The stage of gestation at the time of irradiation varied from 14 to 21 days. The newborn rats were irradiated at 0, 1 and 2 days of age. The effect of irradiation of foetus and newborn rats depends on the age of the animal at the time of irradiation. This effect was specially important at the beginning of the foetal life. Neonatal mortality, growth of body weight and adult brain development were investigated. A modification of germ cell radiosensitivity during the period studied, was emphasized

Abstract (French)

Des femelles gravides et des rats nouveaux-nes ont ete exposes a une irradiation gamma de 150 rads. Le stade de gestation au moment de l'irradiation variait de 14 a 21 jours. Les rats nouveaux-nes etaient irradies a 0, 1 et 2 jours. L'effet d'une irradiation du foetus et du rat nouveau-ne depend de l'age de l'animal lorsqu'il recoit les rayons. Cet effet etait particulierement important au debut de la vie foetale. On a etudie la mortalite neonatale, la croissance corporelle et le developpement du cortex cerebral de l'adulte. On a mis en evidence une modification de la radiosensibilite des cellules germinales au cours de la periode etudiee
