凝胶型99Mo-99mTc发生器研究现状

与裂变型⁹⁹Mo-^99mTc发生器相比，凝胶型⁹⁹Mo-^99mTc发生器制备^99mTc具有工艺简单、产生的放射性废物容易处理、对环境影响小等优点。本文主要论述了凝胶型⁹⁹Mo-^99mTc发生器与裂变型⁹⁹Mo-99mTc发生器的区别，堆照生产⁹⁹Mo原料和凝胶材料的研究进展，凝胶结构以及凝胶组分等多种条件因素对凝胶型⁹⁹Mo-^99mTc发生器性能的影响等，并对低比活度⁹⁹Mo生产^99mTc的研究进展进行综述。

Current Status of99Mo-99mTc Gel Type Generator

Compared to the fission type⁹⁹Mo-^99mTc generator, the gel type⁹⁹Mo-^99mTc generator had the advantages of simple process, easy treatment of radioactive waste and small impact on the environment. This paper mainly discussed the difference between the gel type⁹⁹Mo-^99mTc generator and the fission type⁹⁹Mo-^99mTc generator, the research status of reactor produced⁹⁹Mo and the gel matrix of generator. Moreover, the influence of the gel structure and composition on the performance of the gel type⁹⁹Mo-^99mTc generator were discussed. Finally a brief summary of the research of⁹⁹Tc production by using low specific activity⁹⁹Mo production was presented.
