Abstract
Process for preparing a radionuclide generator for producing Tc-99m or Re-188. A clear solution containing a metallic cation and an anion comprising W-188 or Mo-99 is provided. The metallic cation is present in the solution as a dissolved complex of the metallic cation and a complexing agent and/or the anion being present in the solution as a dissolved complex of the anion and a complexing agent. The dissolved complex(es) are decomposed to form a slurry containing a precipitate of the metallic cation and the anion. The precipitate is transferred to an elutable container of a radionuclide generator.
