Abstract: A method for recovering a parent radionuclide from a radionuclide generator is disclosed where the parent radionuclide is adsorbed to a stationary phase. The method contains a series of elutions. At least one elution is with an alcohol. At least one elution with water. At least one elution is with a mineral acid other than hydrochloric acid that is paused to soak the stationary phase with the mineral acid.

Abstract: A 68Ge/68Ga generator for a continuous production of a 68Ga daughter nuclide, wherein the 68Ge parent nuclide thereof is specifically adsorbed to an inorganic support material and wherein said 68Ge parent nuclide continuously decays to 68Ga by electron capture at a half-life of 270.82 d, wherein the inorganic support material is at least one oxide of a metal being selected from the group consisting of: Vanadium, Niobium and Tantalum. The use of at least one oxide of a metal being selected from the group consisting of: Vanadium, Niobium and Tantalum as an inorganic support material for the manufacture of a 68Ge/68Ga generator for pharmaceutical purposes. With the inorganic support material of the present invention, it is possible to load 68Ge/68Ga generators with up to 8000 MBq of 68Ge (corresponding to 80 ?g Germanium).

Abstract: The present invention relates to a column chromatographic method of manufacturing non-carrier-added high-purity 177Lu compounds for medicinal purposes. In the method in accordance with the invention a cation exchanger and a suitable chelating agent are used. With the method in accordance with the invention it is possible for the first time to provide non-carrier-added high-purity 177Lu compounds in milligram amounts for pharmaceutical-medicinal purposes from 176Yb compounds irradiated with thermal neutrons, the radionuclides 177Lu and 176Yb being present in an approximate mass ratio of 1:102 to 1:1010 for purification.

Abstract: The present invention relates to a 68Ga generator, wherein the 68Ge parent nuclide thereof is attached specifically to a support through a triethoxyphenyl group and continuously disintegrates to 68Ga, the triethoxyphenyl group being covalently bound to a support material through a linker.
Abstract: The present invention refers to a method of treating a cancerous or non-cancerous skin lesion of a subject, e.g. a human patient, by epidermal radioisotope therapy, a specialized type of brachytherapy, comprising the steps of (a) defining and marking an area of skin to be treated; (b) covering said area with a protective layer, e.g. a protective film or foil; (c) applying a tailor-made radioactive source by applying a layer of a radioactive source material on said protective layer, such that said area is covered by said material while any area not to be treated is spared; and (d) removing the radioactive source after a predetermined time period of irradiation.
