Method for the simultaneous preparation of radon-211, xenon-125, xenon-123, astatine-211, iodine-125 and iodine-123
A method is described for simultaneously preparing a mixture of about equal amounts of /sup 211/Rn and /sup 125/Xe, and a second mixture of about equal amounts of /sup 211/At and /sup 123/I with a proton-irradiation procedure followed by a one-step chemical procedure. The method comprises: irradiating a body of material selected from the group consisting of /sup 232/Th and /sup 238/U for about 15 hours with protons that have been accelerated to at least 2 GeV; promptly dissolving the irradiated body of material in a vessel containing a mixture of hydrochloric acid, nitric acid and hydrofluoric acid; and forcing a stream of helium (He) carrier gas into the vessel at a predetermined flow rate to entrain radionuclides of gaseous /sup 210/Rn, /sup 211/Rn, /sup 123/Xe and /sup 125/Xe and trace amounts of radiohalogens and remove them from the vessel.
