摘　　要：针对目前诊断水平剂量计缺少校准装置的现状,采用X射线机、定位装置和温度气压测量仪等组成标准辐射场,建立诊断水平剂量计校准装置;通过对辐射场的空气比释动能进行测量和分析,得出其相对不确定度U=3.8%(k=2);此标准辐射场能满足诊断水平剂量计的校准.In view of the current situation of lacking diagnostic level dosimeter calibrating unit, a standard radiation condition composed of X-ray equipment, positioning device, temperature measuring instrument and barometric pressure measuring instrument was provided, thus building the standard condition for the calibration of diagnostic level dosimeter. The uncertainty of this radiation condition was evaluated as U = 3.8% （k = 2） by measuring and analyzing the air kerma of the radiation field. This standard radiation condition can meet the calibration of diagnostic level dosimeter.
