The radionuclide 95mTc, which has a half-life of 61(2)days and emits a number of gamma-rays, may be used in radiochemical analysis as a yield tracer for the long-lived fission product 99Tc. In this work, we present (i) the production of 95mTc via an (alpha, 2n) reaction with stable 93Nb (a method which does not result in the production of any 97mTc, 98Tc or 99Tc), (ii) the chemical separation of 95mTc from niobium via coprecipitation, liquid-liquid extraction and liquid chromatography, and (iii) the secondary standardisation of 95mTc with high-resolution gamma-ray spectrometry and an ionisation chamber system.
放射性核素95mTc的半衰期为61(2)天，会发射多种伽马射线，可在放射化学分析中用作长寿命裂变产物99Tc的产额示踪剂。在本工作中，我们展示了：(i) 通过与稳定的93Nb发生(α, 2n)反应来制备95mTc（该方法不会产生任何97mTc、98Tc或99Tc）；(ii) 通过共沉淀、液-液萃取和液相色谱从铌中化学分离95mTc；以及(iii) 使用高分辨率伽马射线光谱法和电离室系统对95mTc进行二次标准化。
