Section: claims

1. A method of producing a rhenium-188 radionuclide generator, comprising: irradiating a water soluble irradiation target selected from the group consisting of sodium tungstate and lithium tungstate, reacting the irradiated target with an aqueous zirconium solution to obtain an insoluble zirconium tungstate gel, and disposing the zirconium tungstate in an elutable container to obtain the rhenium-188 radionuclide generator. 2. The method of claim 1 wherein the irradiation target is sodium tungstate. 3. A method of producing rhenium-188 comprising irradiating a water soluble irradiation target selected from the group consisting of sodium tungstate and lithium tungstate, reacting the irradiated target with an aqueous zirconium solution to obtain an insoluble zirconium tungstate gel, disposing the zirconium tungstate in an elutable container and eluting the gel to recover rhenium-188. 4. The method of claim 3 wherein the irradiation target is sodium tungstate.
