摘要

利用电子静电加速器和高频高压电子加速器，在1.0～3.0MeV能量范围内，测定了两种聚乙烯材料中的剂量深度分布；比较了Al、Fe、Cu、Pb 4种衬底金属板，对受辐照材料吸收剂量深度分布的影响；考察了材料中吸收剂量的边界效应。吸收剂量测量的总不确定度为7.8%。优化电子束辐射加工工艺是实现辐照产品质量控制的一种有用的实验方法。

Abstract

The dose distribution in two kinds of polyethylene materials were determined by use of electron beam from 1.0~3.0 MeV electron accelerator. The effects of four different metal base-plate such as Al、Fe、Cu and Pb for dose depth distribution in materials were compared. And the boundary effects of absorbed dose were also observed. The expand uncertainty of absorbed dose measurement was 7.8%. This work is a useful experimental method for optimizing technology of radiation processing and realizing quality control of irradiation products.
