摘要： Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

摘要： Compositions comprising high levels of high specific activity copper-64, and process for preparing said compositions. The compositions comprise from about 2 Ci to about 15 Ci of copper-64 and have specific activities up to about 3800 mCi copper-64 per microgram of copper. The processes for preparing said compositions comprise bombarding a nickel-64 target with a low energy, high current proton beam, and purifying the copper-64 from other metals by a process comprising ion exchange chromatography or a process comprising a combination of extraction chromatography and ion exchange chromatography.

摘要： Methods and systems are provided for cyclical enrichment, especially of rare earth elements and isotopes. A tube, or ampule, optionally with one crucible, or with two coaxially opposite crucibles in fluid communication, is used to hold a source material in vacuum and irradiate the source material to enrich it with product material. Following the irradiation of the source substance (e.g., Yb, enriched with 176Yb) to yield the product substance (e.g., 177Lu), the mixture may be sublimated to remove most of the source substance and concentrate the product material, e.g., by heating the lower part and cooling the upper part of the tube, to condense sublimated source material at the top of the tube. Consecutively, the concentrated product substance may be purified, while the solidified source structure may be reused in irradiation/sublimation cycles to further enrich and concentrate the product material.

摘要： Disclosed are galvanic cells and methods for treating a molten salt by use of the galvanic cells. The galvanic cell can provide anti-corrosion treatment and improved corrosion resistance via electrochemical and chemical reactions involving a corrosive impurity in a molten salt. Reaction products of the chemical and electrochemical reactions include hydrogen gas that can carry hydrogen isotopes evolved in the molten salt. The system can also include removal of the hydrogen gas from the molten salt and separation and recovery of tritium contained therein.

摘要： Disclosed herein are rubidium elution systems comprising a primary assembly including a 82Sr/82Rb generator, an activity detector, a waste container, a pump system, a sensor, a tubing circuit, at least one valve, and a computer; and a dose calibrator outside the primary assembly. The system may have an interface for configuring the dose calibrator, and a locking means for preventing access to the interface and reconfigurations of its parameters. Moreover, the dose calibrator may be in electronic communication with the computer of the system. Furthermore, the electronic communication can be embodied with an electronic cable having a breakaway connector. Also, the dose calibrator may be positioned on a mobile platform.

摘要： The present disclosure relates processes and systems for producing and/or purifying 68Ga from an irradiated substrate of 68Zn. In some embodiments, the process rely on the use two cation-exchange chromatography columns to separate 68Ga from 68Zn and other radionuclides and metallic impurities. The process achieves a high overall yield of 68Ga and a high effective molar activity while being implementable in a time compatible with the short half-life of 68Ga. In additional embodiments, the process is implemented by an automated system.

摘要： The present disclosure relates in general to nuclear medicine and generators for the production of radiopharmaceuticals for medical use. In particular, present disclosure relates to a generator column that resists high heat such as depyrogenation and sterilization. This allows some steps of the preparation of the column to be performed in a non-sterile environment. This also allows the generator column to be reusable. The present disclosure further describes methods for the preparation of a generator where a parent radioisotope is charged on the column matrix before or after the matrix is loaded in the column.
