【摘要】 乏燃料后处理工艺过程中的萃余液、洗涤液中的α放射性浓度低,传统取样分析技术局限性较大。本文提出了用玻璃闪烁体接触溶液的方式在线测量溶液中的α放射性浓度,并据此生产出了符合闪烁体性能要求的玻璃闪烁体,研制出了闪烁玻璃探测系统,其主要性能指标达到了预期要求。更多还原

【Abstract】 It is difficult to determine the concentration of α-emitting nuclides of raffinate and detergent in process feed solutions due to its low concentration.The conventional radiochemical analysis methods cannot meet the new demand.A novel analytic technique using scintillating glass to determine the concentration ofα-emitting nuclides in liquid was present in this paper.The glasses and detection system were build and its performance index met the requirements and achieved the expected effect.更多还原
