摘要

设计了带铅屏蔽和能对空间各场点进行定点测量的照射盒。成功地解决了空间各场点定点测量的问题

克服了以前场点测量数据分散性较大的缺陷

并对探测器的屏蔽效应修正进行了实验验证。在此基础上对物理测试探测器刻度用场点的光子注量进行了实验测定

给出了刻度场点的光子注量。

Abstract

The irradiation cases with lead shield were designed to successfully measure photon fluence at every designated point in the radiation flied. The main shortcoming of previous

i.e. larger dispersion of the measurement data at the same point

was overcome due to the use of lead shield to weaken effect of low-energy scattered γ-ray on the detector. Effectiveness of using these irradiation cases was experimentally verified

and the data on absorbed dose photon fluence rate at several points were obtained with a total uncertainty of less than 7%.
