Abstract
Mouse embryos of the one-cell stage or the 32- to 64-cell stage were e xposed to various X-ray doses (one-cell stage: 0.25-2 Gy; 32- to 64-ce ll stage: 1-3 Gy). It turned out that the shape of the dose-response c urves is statistically compatible with the assumption derived from bio logical considerations that there is no threshold for radiation-induce d malformations in the case of the exposure of one-cell embryos, where as there is a threshold dose (close to 1 Gy) in the case of the exposu re of 32- to 64-cell embryos.
