[Effect of single-dose external gamma-irradiation of 0.5 g on the development of rat's embryos].
Primigravida 4-month rats were exposed to single whole-body external gamma-radiation (137Cs, 0.5 Gy) during organogenesis on days 9 and 15 of pregnancy. The embryotoxic effect of radiation was studied on the 20th day of pregnancy. The irradiation caused significant growth disorders characterized mainly by a nonuniform hypoplasia of fetus organs. This effect was most pronounced in fetuses irradiated on the 15th day of the intrauterine development.
