Abstract: A method of separating actinium and/or radium from proton-irradiated thorium metal. The thorium metal is irradiated to produce isotopes including thorium, actinium and/or radium. The resultant product is dissolved in solution and a selective precipitant is used to precipitate a bulk portion of the thorium. The precipitated thorium can be recovered. Chromatography is carried out on the remaining solution to remove residual thorium and to separate the actinium from the radium.

Abstract: The present invention is directed to a system, apparatus, and method for producing gallium radioisotopes on particle accelerators using solid targets and a Ga-68 composition produced by this method. The solid target assembly apparatus has a metal disc and a zinc portion on the top of the disc. The apparatus is made by preparing a quantity of zinc, depositing it onto a metal disc, melting the zinc, and allowing it to cool and solidify. The disc surface may be prepared before applying zinc to it in order to facilitate bonding between the substrate and the zinc. Ga-68 is produced by placing the apparatus in a cyclotron target irradiation station, irradiating it, separating it from the irradiated Zn, and collecting and storing the separated Ga-68. The Ga-68 composition has the following quotient of activity quantity ratios: Ga-67/Ga-68 less than 1, and Ga-67/Ga-68 less than 1.

Abstract: Systems and methods for separation or isolation of technetium radioisotopes from aqueous solutions of radioactive or non-radioactive molybdate salts using a polyalkyl glycol-based cross-linked polyether polymer. Some embodiments can be used for the effective purification of radioactive technetium-99m produced from low specific activity 99Mo.

Abstract: Disclosed are a variety of self-supporting, multilayer carbon films that include a layer of both a non-diamond-like carbon, for example, graphitic or amorphous carbon (or a-C), and a layer of diamond-like carbon (DLC). A wide range of multilayer configurations may be constructed depending on the particular combination of properties desired in the final product including, for example, a tri-layer construction including a single DLC layer sandwiched between two layers of amorphous carbon. Also disclosed are example embodiments of methods for producing such composite multilayer films that include preparing an appropriate substrate to include a deposition surface of sufficient smoothness, applying a parting or release agent to the deposition surface, depositing a plurality of layer carbon layers including both an amorphous carbon layer and a DLC layer to form the composite carbon film and removing the composite carbon film from the substrate.

Abstract: An apparatus for producing 18F-Fluoride by using a particle beam to irradiate conversion medium in gaseous or liquid form. The irradiated conversion medium is contained in a chamber surrounded by a Fluoride adsorbing material to which the produced 18F-Fluoride adheres. The adsorption properties of the Fluoride adsorbing material are manipulated by an adsorption enhancing/decreasing element. A solvent dissolves the produced 18F-Fluoride off of the Fluoride adsorbing material while it is in the chamber. The solvent is then processed to obtain the 18F-Fluoride.

Abstract: A system and method for producing 18F-Fluroide by using a proton beam to irradiate 180xygen in gasous form. The irradiated 180xygen is contained in a chamber that includes at least one component to which the produced 18F-Fluoride adheres. A solvent dissolves the produced 18F-Fluoride off of the at least one component while it is in the chjamber. The solvent is then processed to obtain the 18F-Fluoride.
