Nowadays, cobalt isotopes Co, Co, and Co are considered to be promising radionuclides in nuclear medicine, with Co receiving the most attention as an isotope for diagnostics by positron emission tomography. One of the current research directions is dedicated to its production using electron accelerators (via photonuclear method). In our work, the yields of nuclear reactions occurring during the irradiation of Ni and Ni by bremsstrahlung photons with energy up to 55 MeV were determined. A method of fast and simple cobalt isotopes separation from irradiated targets using extraction chromatography was developed.
如今，钴同位素 Co、Co 和 Co 被认为是核医学中很有前途的放射性核素，其中 Co 作为正电子发射断层扫描诊断用的同位素受到了最多的关注。目前的研究方向之一是使用电子加速器（通过光核方法）来生产它。在我们的工作中，确定了用能量高达 55 MeV 的韧致辐射光子辐照 Ni 和 Ni 时发生的核反应的产额。开发了一种使用萃取色谱法从辐照靶中快速简便地分离钴同位素的方法。
