A process for the separation ofTc from molybdenum targets is described. The method for separation ofTc isotope from molybdenum targets includes: i) providing an initial multicomponent mixture of elements, the mixture containingTc; ii) dissolving the multicomponent mixture of elements with an oxidizing agent to oxidize the mixture of elements; iii) heating the mixture of elements at a temperature sufficiently high enough to sublimate a vaporized compound containingTc; iv) condensing the vaporized compound containingTc to form a reaction product; v) adding a base to the condensed reaction product to dissolve theTc containing reaction product to form sodium pertechnetate (NaTcO); and vii) purifying the crude solution of sodium pertechnetate NaTcOusing column chromatography to provide theTc isotope as a radiochemical compound.

System and method for metallic isotope separation by a combined thermal-vacuum distillation process

An article formed of a metal alloy is covered at least partially with a metal hydride and a shell metal to form an assembly. Load is applied to the assembly and the assembly is heated. The shell metal deforms around the article and the metal hydride and forms a gas proof seal. The metal hydride thermally decomposes to form hydrogen gas. At least a portion of the hydrogen gas dissociates and moves as monoatomic hydrogen into the article. The metal alloy can be a zirconium metal alloy, the metal hydride can be a zirconium metal hydride, and the shell metal can be substantially copper.

Mechanically-assisted gaseous addition of hydrogen to metal alloys

Apparatuses and methods for production of molybdenum targets, and the formed molybdenum targets, used to produce Tc-99m are described. The target includes a copper support plate having a front face and a back face. The copper support plate desirably has dimensions of thickness of about 2.8 mm, a length of about 65 mm and a width of about 30 mm; and the copper support plate desirably has either a circular or an elliptical cavity centrally formed therein by pressing molybdenum powder into the front face with a depth of about 200-400 microns. Also, the copper support plate includes cooling channels dispensed at the back face; wherein the copper support plate is water cooled by a flow of water during irradiation by a proton beam. Molybdenum powder is embedded and compressed onto the cavity of the copper support plate thereby creating a thin layer of molybdenum onto the copper support plate.

A method for selectively photoionizing odd mass Zr atoms. Atomic vapours are subjected to three resonant and are non resonant laser pulses to raise the energy of Zr atoms from the J=2 ground state, to a J=1 first intermediate state, to a J=(second intermediate state and to a third intermediate state prior to ionization. Quantum mechanical selection rules applicable to linearly polarized light and hyperfine interactions are exploited to produce odd mass selectivity
