We studied the production of ⁶⁷Cu medical radioisotope by irradiating Zn targets of natural isotopic composition by bremsstrahlung photons with endpoint energies of 30 and 40 MeV. Cross-sections per equivalent quantum of ⁶⁷Cu, ⁶⁴Cu, ⁶²Zn, ⁶³Zn, ⁶⁵Zn, and ^69mZn activation products were measured. The specific activities of ⁶⁷Cu were found to be 2.04 and 4.78 µCi/(µA∙h∙g) at the end of the bombardment for 30 and 40 MeV bremsstrahlung maximum energies, respectively.

医学同位素⁶⁷ Cu的光核生产

我们研究了通过致发光光子以30和40 MeV的最终能量辐照天然同位素组成的Zn靶标来生产⁶⁷ Cu医用放射性同位素的方法。测量了每当量量子⁶⁷ Cu，⁶⁴ Cu，⁶² Zn，⁶³ Zn，⁶⁵ Zn和^69m Zn活化产物的横截面。轰击结束时，对于30 MeV和40 MeV stra致最大能量，在轰击结束时⁶⁷ Cu的比活分别为2.04和4.78 µCi /（µA∙h∙g）。
