Section: claims

1. A method of producing radioactive isotope copper-67 comprising:providing a target in liquid form comprising gallium-71;directing an electron beam onto a bremsstrahlung converter in order to generate photons;said electron beam having a beam energy of at least 30 MeV; and,irradiating said target with said photons in order to isotopically convert at least a portion of the target to copper-67; and,radiochemically separating the copper in the target from other elements in the target, wherein no less than ninety nine percent of the radioactive copper is made up of copper-67. 2. The method of claim 1 wherein said electron beam has an energy of at least 100 MeV. 3. The method of claim 1 wherein said converter is composed of either tungsten or tantalum. 4. The method of claim 1 wherein said copper has a specific copper-67 activity of at least 5.6 Ci/microgram. 5. The method of claim 1 wherein said electron beam has an average energy of 40 MeV and an average power of 50 kW. 6. The method of claim 5 wherein said copper-67 has a specific activity of at least 5.6 Ci/microgram. 7. A method of producing radioactive isotope copper-67 comprising:providing a target comprising gallium-71 in liquid form;positioning said target within a target apparatus; said apparatus having a jacket, including a plurality of water-cooling channels running there through, and a container comprised of Boron Nitride in the shape of a cylinder or a wedge;directing an electron beam onto a bremsstrahlung converter in order to generate photons;said electron beam having a beam energy of at least 30 MeV; and,irradiating said target with said photons in order to isotopically convert at least a portion of the target to copper-67.
