| 摘 要： | 本文主要介绍复制 ISO4037中用于剂量仪表校准的四个过滤 X-射线参考辐射(宽谱,窄谱,低照射量率和高照射量率)的装置及检测结果。测试结果表明,除宽谱的110kV 能量点的分辨率超过标准规定的要求外,各个规范的参考辐射的射束质、场的均匀性和散射特性均符合了 ISO4037的要求。

| Abstract: | A apparatus that can reproduce four filtered x-ray reference radiation(i.e.narrow spectrum,broad spectrum,low exposure rate and highexposure rate),which are recommended by ISO4037 to be used for calibra-ting dosimeters is introduced and the test results are given in the paper.The results show that the beam quality,uniformity and scattering characteri-stic of each reference radiation comply with the international standard ofISO4037 with the exception of the resolution of broad spectrum radiation atthe energy of 110 kV. |
