摘要
快中子照相是一种优良的无损检测技术,它有着 X 射线、热中子照相等所不具有的独特优势。本文介绍了作者分别采用 Am-Be 同位素中子源和中子发生器进行的快中子照相研究,并利用自制的 Gd2O2S:Tb 快 241中子转换发光屏进行探测,成功实现照相。
As a non-destructive testing technique, fast neutron radiography has many unique advantages comparing with X-ray and thermal neutron radiography. This article represents two different neutron sources to study fast neutron radiography, one is 241Am-Be neutron source, and the other is neutron generator. The fast neutrons were detected by a scintillator screen using Gd2O2S:Tb as phosphor. A series of results were obtained and discussed.
