摘要
裂变产物的分析在80年代的10年中取得了显著进展。裂变产物的现场测量和废物包装件的整体测量方法已被建立,以满足放射性废物处理和处置工作的需要。活化分析以及非放射的仪器分析方法被用来测量长寿命裂变产物核素,其分析灵敏度优于传统的放化分析法。契连可夫计数技术以及快速放化分析方面也有新的工作发表。本文从方法学角度对这些进展进行了综述。
A great deal of progress has been achieved in analysis of fission products during the 1980s. In situ analysis of fission products and direct assay of radiowaste packages have been developed to suit the needs of radiowaste treatment and disposal. Activation analysis and non-radiometric method have been used to measure long-lived fission product nuclides. Their sensitivity is superior to that of traditional radiochemical analysis. Some new work on the Cherenkov counting technique and rapid radiochemical analysis has been published. In this article the progress has been reviewed from the point of view of methodology.
