摘要：
The present disclosure provides a method and an apparatus for producing astatine-211 from alpha-particle bombardment of bismuth-209. The disclosure also relates to a method and apparatus of producing other radionuclides from target nuclides. The apparatus includes a plate having a recessed portion. The recessed portion has a generally inert surface of ceramic or metal, preferably aluminium oxide that does not react with molten bismuth. A bismuth target is placed in the recessed portion and held therein by a foil cover. The foil has a melting temperature greater than target nuclide (i.e., for bismuth, >；271° C.). The foil and target nuclide are held in the recessed portion by a cover that is fastened over the foil. The cover has an aperture to allow a beam of radiation, such as alpha particles, from a cyclotron or other accelerator to pass through the cover to the foil and target nuclide.
