During the production of F, as a result of the interaction of the beam of protons and secondary neutrons with the structural elements of the target body, many radionuclide impurities are created in the cyclotron. As part of this work, we theoretically predicted which isotopes would be activated in the target tantalum or silver bodies. Subsequently, we used gamma spectrometry analysis to verify these predictions. The results were compared with the work of other authors who studied titanium and niobium as materials for making the target body. Tantalum has been evaluated as the most favorable in terms of generating radionuclide impurities during the production of F by irradiation of O-enriched water in accelerated proton cyclotrons. Only three radionuclides were identified in the tested samples: W, Hf, and Ta with a half-life of fewer than 120 days. The remaining reactions led to the formation of stable isotopes.
在 F 的生产过程中，由于质子束和次级中子与靶体结构元素的相互作用，在回旋加速器中产生了许多放射性核素杂质。在这项工作中，我们从理论上预测了哪些同位素将在靶体钽或银体中被激活。随后，我们使用伽马谱分析来验证这些预测。将结果与研究钛和铌作为制造靶体材料的其他作者的工作进行了比较。在利用富氧水在加速质子回旋加速器中辐照生产 F 的过程中，评估了钽是产生放射性核素杂质最有利的材料。在测试样品中仅鉴定出三种半衰期少于 120 天的放射性核素：W、Hf 和 Ta。其余反应导致稳定同位素的形成。
