Abstract

Cu and Cu are theragnostic pair radionuclides with promising application in the nuclear medicine. Cu is PET nuclide for the non-invasive diagnosis and Cu is beta emitter for therapy of various cancers. This study discusses optimization efforts in the production of these radioactive coppers carried out with 30 MeV cyclotron. Optimized conditions include target preparation, chemical separation, and quality control. The production routes of Cu and Cu were studied based on the nuclear reactions of Ni(p,n)Cu and Zn(p,α)Cu. The produced Cu and Cu have >99.9% of the radionuclidic purity. The yield at the end of bombardment (EOB) of Cu and Cu is 28.5 MBq/μAh and Cu is 0.58 MBq/μAh, respectively.

摘要

铜-64和铜-67是在核医学中有应用前景的诊疗一体化放射性核素对。铜-64是用于非侵入性诊断的正电子发射断层显像(PET)核素,而铜-67是用于各种癌症治疗的β发射体。本研究讨论了利用30兆电子伏回旋加速器生产这些放射性铜的优化工作。优化条件包括靶制备、化学分离和质量控制。基于镍(p,n)铜-64和锌(p,α)铜-67的核反应研究了铜-64和铜-67的生产路线。所生产的铜-64和铜-67的放射性核素纯度大于99.9%。铜-64和铜-67在轰击结束时(EOB)的产率分别为28.5兆贝可/微安时和铜-67为0.58兆贝可/微安时。
