BS>The effect of x radiation was studied on the growth of os ilium, the femur, the tibia, and the fibula in the fetus of rats. Pregnant female rats were exposed to a dose of 250 R, this either of single irradiation on the 11th, 12th, 13th, 14th, and 15th days following fertilization or of chronic irradiation applied over the 1st to the 19th day of pregnancy. The fetuses were removed on the 19th day of pregnancy. The exposure was ascertained to inhibit or to stimulate the growth in dependence on the degree of the development of the fetus at a time of exposure. It was verified that during development, the bones manifested stages of increased radiosensitivity as well as of relative radioresistance. The most marked changes were observed in the fibula. (auth)
