摘要
高丰度的氙同位素被广泛应用于医疗诊断、惯性导航、基础物理以及放射性同位素生产等领域,其中124Xe被用来生产放射性同位素125I,超极化气体129Xe和131Xe是肺部磁共振成像以及核磁共振陀螺仪的关键材料,而136Xe被用于浓缩氙观测站。采用专用设备进行氙同位素分离是目前获取氙同位素最有效的方法。本文对氙同位素的应用领域、分离方法以及氙同位素的生产现状进行综述。
Xenon isotopes with high abundance are widely applied in fields such as medical diagnosis, inertial navigation, basic physics and the production of radioisotopes. 124Xe is used in the production of the radioisotope 125I, hyperpolarized 129Xe and ]3~Xe are the key materials of magnetic resonance imaging(MRI)and nuclear magnetic resonance gyros(NMRG), and la6Xe is used in the enriched xenon observatory(EXO). Separating xenon isotopes by special equipment is proved to be the most efficient method for obtaining xenon isotopes. The application fields, separation method and production current status of Xe isotopes are reviewed.
