摘要
Ｘ射线照射量（治疗水平）标准装置是由标准剂量仪，Ｘ射线照射源，测量车、定位系统及其辅助设备组成。本文作者主要介绍标准装置各个部分的构成及技术参数。该标准装置于１９９１年通过国家技术监督局认证，尔后，正式开展放射仪表的检定和校准工作。
The standard for X-ray exposure(therapy level) was studied and set up in Secondary Standard Dosimetry Laboratory(SSDL) ,Beijing. The SSDL is equipped with standard dosemeters, X-ray machine, measuring rail and cart, positioning system and auxiliary devices. The parameters of X-ray radiation field and configuration of facilities used for verification of dosemeters are presented. The licence for calibration of dosemeters in China was issued by National Bureau of Metrology and the calibrating service has been ,developed.
