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: Molecule for attaching a radioactive parent nuclide to a support, comprising at least one functional group for attaching the radioactive parent nuclide; and a molecular moiety suitable for establishing a nonpolar bond to the support.

Abstract: Disclosed is a layer structure for epidermal radionuclide therapy (brachytherapy) of a patient comprising, from a patient's view, a proximal adherent layer for applying the layer structure on the skin surface to be treated of a patient; a flexible, transparent carrier layer that from a patient's view is located in a distal direction on the adherent layer; and at least one radionuclide-containing emission layer located on the carrier layer, the adherent layer and the carrier layer with regard to their components and thickness being formed such that they are essentially transparent for ? and ? radiation. The layer structure is suited particularly for radiotherapeutic treatment of the basal-cell carcinoma (BCC) and the squamous cell carcinoma (SCC). With the aid of the layer structure, geometrically complex skin lesions caused by a tumor, as occurring e.g. on the outer edge of the auricle, may be treated easily.
