  • Patent number: 11421336
    Abstract: Disclosed herein are a system and method for electroplating an alpha emitting radionuclide, such as an actinide, for use in alpha spectroscopy. The electrodeposition system for electroplating an alpha emitting radionuclide can include an electroplating cell containing a solution of an electrolyte and the alpha emitting radionuclide, a metal target within the electroplating cell, and a metal anode at a distance from the metal target. The system also includes a platform for supporting the electroplating cell, coupling mechanism connected to the platform, an electric motor on the elastic cushion, and a flywheel with an uneven weight distribution operatively connected to the electric motor. Rotation of the unevenly distributed flywheel generates a vibration in the electroplating cell which dislodges gas bubbles that have formed between the metal target and the metal anode.

  • Patent number: 11189388
    Abstract: Methods for purifying the molybdenum-99 isotope are disclosed. Molybdenum-99 is loaded onto an anion exchange column and extracted. In some embodiments, the extraction solution may include nitric acid and nitrate salts. In other embodiments, a two stage elution is performed in which a nitric acid containing eluent and a hydroxide containing eluent are used in succession to extract molybdenum-99.
