WITH THE addition of the atom bomb to the armamentarium of modern warfare, large numbers of persons may be subjected not only to trauma but also to the effects of whole body x-irradiation. With the exception of experimental work reported in the literature on the effects of local x-rays on fracture healing, we have been unable to find any reports on the effect of whole body exposure to x-rays on the healing of fractures.
