Delayed induction of ornithine decarboxylase in mouse skin after irradiation with beta-rays.
Irradiation with 90Sr-90Y beta rays induced ornithine decarboxylase (ODC) activity in mouse skin. Maximum activity appeared after about 17 days, at the time of appearance of skin injuries. These findings suggest the presence of tumor-promoting activity of beta rays.
