中国医用99Mo及99Mo-99Tcm发生器的发展

⁹⁹Tc^m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。⁹⁹Tc^m在临床上主要由其母体核素⁹⁹Mo衰变通过⁹⁹Mo-⁹⁹Tc^m发生器获得。中国从20世纪60年代末开始医用⁹⁹Mo与⁹⁹Mo-⁹⁹Tc^m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-⁹⁹Tc^m发生器的发展进行了简要回顾，分析了我国在⁹⁹Mo及⁹⁹Mo-⁹⁹Tc^m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。

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

⁹⁹Tc^m is the most frequently used for clinical diagnosis in nuclear medicine, accounting for some 70% of all radionuclides used for diagnosis.⁹⁹Tc^m is mainly produced from decay of its parent nuclide ⁹⁹Mo via the⁹⁹Mo-⁹⁹Tc^m generators. China has developed technology for medical ⁹⁹Mo and⁹⁹Mo-⁹⁹Tc^m generators since 1960s, and has made remarkable achievements. In present work, the development of medical ⁹⁹Mo and⁹⁹Mo-⁹⁹Tc^m generators in China is briefly reviewed, and involved problems for production of medical ⁹⁹Mo and ⁹⁹Mo-⁹⁹Tc^m generators are discussed. Furthermore, some suggestions on the future development of 99Mo and ⁹⁹Mo-⁹⁹Tc^m generators are provided, which is expected to promote the further development of radioisotopes technology in China.
