中国医用99Mo及99Mo-99Tcm发生器的发展

    Development of Medical 99Mo and 99Mo-99Tcm Generator in China

    • 摘要: 99Tcm是核医学临床诊断应用最为广泛的放射性核素,其使用量占所有诊断用放射性核素的70%左右。99Tcm在临床上主要由其母体核素99Mo衰变通过99Mo-99Tcm发生器获得。中国从20世纪60年代末开始医用99Mo与99Mo-99Tcm发生器的研制工作,并取得了十分瞩目的成就。本文对我国医用99Mo及99Mo-99Tcm发生器的发展进行了简要回顾,分析了我国在99Mo及99Mo-99Tcm发生器生产方面存在的问题,并对其今后的发展提出了建议,以期促进国内放射性同位素技术进一步的发展。

       

      Abstract: 99Tcm is the most frequently used for clinical diagnosis in nuclear medicine, accounting for some 70% of all radionuclides used for diagnosis. 99Tcm is mainly produced from decay of its parent nuclide 99Mo via the 99Mo-99Tcm generators. China has developed technology for medical 99Mo and 99Mo-99Tcm generators since 1960s, and has made remarkable achievements. In present work, the development of medical 99Mo and 99Mo-99Tcm generators in China is briefly reviewed, and involved problems for production of medical 99Mo and 99Mo-99Tcm generators are discussed. Furthermore, some suggestions on the future development of 99Mo and 99Mo-99Tcm generators are provided, which is expected to promote the further development of radioisotopes technology in China.
