我国后处理工厂中用于钚α活度流线测量的闪烁探测装置,目前唯一仍大量采用的探头材料是ZnS(Ag),但ZnS晶体易于潮解给测量带来不便。本文论述了微量和痕量钚测量的分析方法及国内外研究现状,最终确立了采用新型闪烁材料直接接触测量钚溶液的研究方向。拟建立的这种分析方法在常温常压下进行,操作简单、方便,有望为后处理工艺过程或实验室环境下钚的分析测量提供一种新的途径。
The scintillation detection device used for the measurement of the α-activity stream of plutonium in the reprocessing plant in our country is the only probe material that is still largely used, which is ZnS (Ag). However, the ZnS crystal is easy to deliquescence and causes inconvenience to the measurement. This paper discusses the analytical methods of trace and trace plutonium measurements and the research status at home and abroad, and finally establishes the research direction of direct contact measurement of plutonium solution with new scintillation materials. The proposed analysis method is carried out under normal temperature and pressure, and is simple and convenient to operate. It is expected to provide a new approach for analytical analysis of plutonium in post-treatment process or laboratory environment.
