INTERNAL RADIATION DOSE MEASUREMENTS IN LIVE EXPERIMENTAL ANIMALS. PART I
A study was made of the use of Schulman-Etzel smallvolume dosimeters in the measurement of tissue dose in live animals administered pure helial phagocyt -emitting radioisotopes. The possible extension of this method to similar measurements with mixed helial phagocyt - and pure -emitters is discussed. The technique developed for the measurement of dose to the intestinal mucosa of animals given oral doses of pure helial phagocyt -emitters is described. The technique involves surgical implantation of dosimeters in the walls of the intestinal tract followed by recovery of the dosimeters after dosing. The application of certain correction factors to the measured response of the recovered dosimeters makes it possible to calculate the dose received by the surface of the intestinal mucosa. (auth)
