Comparative radiosensitivity of Wistar and mongrel rats to nonuniform radiation. [X rays]

Data were obtained that are indicative of absence of significant differences between mongrel and Wistar rats, with regard to radiosensitivity to uniform irradiation and exposure with shielding of the abdomen. Radiosensitivity of Wistar rats is reliably greater when the abdominal region is irradiated, according to the LD/sub 50/ criterion.
