核电厂液态流出物中锶-89和锶-90的液闪计数快速测定

Abstract

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
