摘要/Abstract

摘要： 建立了一种核电厂液态流出物中锶-89和锶-90的分析测量方法,通过阳离子交换树脂富集液态流出物中锶-89和锶-90,以锶树脂分离锶-89和锶-90,用低本底闪烁谱仪为测量仪器进行测量,并对相关测量条件进行分析研究。本方法简化了核电厂液态流出物处理流程,并且能够同时测量多个核素,满足核电厂液态流出物中锶-89和锶-90的分析要求。

Abstract: This paper described analysis and measurement method for strontium-89 and strontium-90 in liquid effluent of nuclear power plant. Strontium-89 and strontium-90 in liquid effluent are enriched by cation exchange resin, separated by strontium resin, and measured by low background scintillation spectrometer. The relevant measurement conditions are analyzed and studied. This method simplifies the treatment process of liquid effluent of nuclear power plant. The established method can detect multiple nuclides at the same time, and can fully meet the analysis requirements of strontium-89 and strontium-90 in liquid effluent of nuclear power plant.

Key words: liquid effluent, strontium-89, strontium-90, liquid scintillation counting method
