Schedule of the experiments. In Experiment 1 (a radiation dose–response study), rats were exposed to sham, 1.5, 3, 6, or 12 Gy of cervical X-irradiation at 5 or 6 days old and necropsied at 9 weeks old. In experiment 2 (a study of irradiation at different ages), 12 Gy of cervical X-irradiation was given at 5 or 6 days, 2, 4, or 8 weeks old. In Experiment 3 (a thyroid tumor promotion study), rats were exposed to 12 Gy of cervical X-irradiation at 5 or 6 days old. After the exposure, half of the groups were fed with IDD (The mothers were fed with IDD until weaning at 3.5 weeks old).
