20100064853 | METHODS FOR CHEMICAL RECOVERY OF NON-CARRIER-ADDED RADIOACTIVE TIN FROM IRRADIATED INTERMETALLIC Ti-Sb TARGETS - The invention provides a method of chemical recovery of no-carrier-added radioactive tin (NCA radiotin) from intermetallide TiSb irradiated with accelerated charged particles. An irradiated sample of TiSb can be dissolved in acidic solutions. Antimony can be removed from the solution by extraction with dibutyl ether. Titanium in the form of peroxide can be separated from tin using chromatography on strong anion-exchange resin. In another embodiment NCA radiotin can be separated from iodide solution containing titanium by extraction with benzene, toluene or chloroform. NCA radiotin can be finally purified from the remaining antimony and other impurities using chromatography on silica gel. NCA tin-117 | 03-18-2010 |
20100080726 | COMPOSITION AND METHODS OF PREPARATION OF TARGET MATERIAL FOR PRODUCING RADIONUCLIDES - A composition suitable for use as a target containing antimony to be irradiated by accelerated charged particles (e.g., by protons to produce tin- | 04-01-2010 |
20130010910 | TARGETS AND METHODS FOR TARGET PREPARATION FOR RADIONUCLIDE PRODUCTION - The invention relates to nuclear technology, and to irradiation targets and their preparation. One embodiment of the present invention includes a method for preparation of a target containing intermetallic composition of antimony Ti—Sb, Al—Sb, Cu—Sb, or Ni—Sb in order to produce radionuclides (e.g., tin—117 m) with a beam of accelerated particles. The intermetallic compounds of antimony can be welded by means of diffusion welding to a copper backing cooled during irradiation on the beam of accelerated particles. Another target can be encapsulated into a shell made of metallic niobium, stainless steel, nickel or titanium cooled outside by water during irradiation. Titanium shell can be plated outside by nickel to avoid interaction with the cooling water. | 01-10-2013 |

20110051873 | METHOD FOR PRODUCING RADIOSTRONTIUM - The invention relates to producing radiostrontium. The aim of the invention is to release radiostrontium from a large mass of liquid metal rubidium, thereby making it possible to increase the efficiency of radiostrontium production and simplify the production process. Sorption is carried out directly on the inner shell of a target at a temperature of 275-350° C., or by extracting radiostrontium from circulating rubidium by sorption on the heated surface of a trap at a temperature of 220-350° C., or by filtering liquid rubidium through a filtering element made of a porous material resistant to liquid rubidium. | 03-03-2011 |
20110317795 | METHOD FOR PRODUCING ACTINIUM-225 AND ISOTOPES OF RADIUM AND TARGET FOR IMPLEMENTING SAME - The invention relates to the field of nuclear technology and radiochemistry, more specifically to the production and isolation of radionuclides for medical purposes. The method for producing actinium-225 and isotopes of radium comprises irradiating a solid block of metallic thorium of a thickness of 2 to 30 mm, which is contained within a hermetically sealed casing made of a material which does not react with thorium, with a flow of accelerated charged particles with high intensity. The irradiated metallic thorium is removed from the casing and is either heated with the addition of lanthanum and the distillation of radium or is dissolved in nitric acid with the recovery of actinium-225 by extraction. A target for implementing this method consists of blocks of metallic thorium of a thickness of 2 to 30 mm, which are contained within a hermetically scaled casing made of different materials which do not react with thorium. | 12-29-2011 |

20110216867 | PROCESS AND TARGETS FOR PRODUCTION OF NO-CARRIER-ADDED RADIOTIN - One embodiment of the present invention includes a process for production and recovery of no-carrier-added radioactive tin (NCA radiotin). An antimony target can be irradiated with a beam of accelerated particles forming NCA radiotin, followed by separation of the NCA radiotin from the irradiated target. The target is metallic Sb in a hermetically sealed shell. The shell can be graphite, molybdenum, or stainless steel. The irradiated target can be removed from the shell by chemical or mechanical means, and dissolved in an acidic solution. Sb can be removed from the dissolved irradiated target by extraction. NCA radiotin can be separated from the remaining Sb and other impurities using chromatography on silica gel sorbent. NCA tin-117m can be obtained from this process. NCA tin-117m can be used for labeling organic compounds and biological objects to be applied in medicine for imaging and therapy of various diseases. | 09-08-2011 |
