Hot cell purification of strontium-82, 85 and other isotopes from proton irradiated molybdenum

A process suitable for producing curie quantities of quite pure Sr-82,85 is given. After a Mo target is irradiated with energetic protons having energies greater than about 200 MeV, thus producing a large number of radioactive species, the particular species of Sr-82,85 are substantially separated from the other products by a 6-step process. The process comprises dissolution of the target in H2O2, followed by use of several ion exchange resins, extraction with an organophosphorus compound, and several adjustments of ph values. Other embodiments include processes for producing relatively pure long-lived Rb isotopes, Y-88, and Zr-88
