Abstract
The paper presents a new approach in the integral gamma scanning of rotating waste drums based on solving a first-kind Fredholm integral equation using a small number of measurements. Both numerical experiments and experimental results show that the nuclide inventory of waste drums can be determined accurately using the new approach especially when the waste drums contain multi-gamma emitters.
摘要
本文提出了一种基于使用少量测量值求解第一类弗雷德霍姆积分方程的旋转废物桶积分伽马扫描新方法。数值实验和实验结果均表明，使用该新方法能够准确确定废物桶中的核素存量，尤其是当废物桶含有多种伽马发射体时。
