Design of experiments wherein mice were acutely irradiated with low-LET γ-rays and sacrificed at different times postirradiation. (A) Mice were fed control diet, irradiated, and sacrificed 1 – 48 h postirradiation. (B) Mice were fed control diet or diet supplemented with vitamin A, C, and E. Arrows refer to times postirradiation when mice were sacrificed. Day 8 was chosen for B based on a previous experiment tracking the time course of radiation-induced reductions in nutrient transport.
