Dosimetric criteria for the intestinal form of acute radiation injury in man. An empirical model

On the basis of the results of radiobiological studies on acute nonuniform irradiation of the animal's abdomen a dose dependence has been found for the duration of the injury to barrier properties of the small intestine epithelium, T(D). With relative coordinates x = D/LD50 and y = T (D)/T(LD50), this dependence may be represented by a single function for various animal species.
