摘　　要：本文介绍了由17个省市的35个单位参加的国内外照射个人剂量计第三次比对结果。参加比对的单位中核工业系统所属单位17个,卫生和环保系统单位18个。参加比对的均采用热释光剂量计,共402支剂量计。辐射源是由国防科工委二级站提供的按 ISO 标准的宽、窄系列 X 射线、荧光 X 射线及^(137)Cs 源,辐射能量在17.5—662 keV 范围内,选取8个能量点进行照射。统计的274组数据表明,实测值与参考值比值的平均值为0.966,变异系数为35%;中位值为0.903。按 ICRP 35号报告所要求的不确定度,落在要求范围内的剂量计占87%。In this paper,it is intruduced the results of third intercomparison of External per-sornal dosemeter of 35 domestic independent laboratories,of which there are 17 nuclear in-dustry departments,and 18 ones of medical,health and environment departments.402 per-sormal dose-meter were thermoluminescence dose-meter(TLD).The radiations sources are^(137)Cs,a series of broad and narrow fuloresent and X-ray according to 280 standard provideetby national defence scientific and industrial committee.They were exposured with 8 energiesranged from 17.5 to 662 keV.The 274 data showed that the mean of ratio of measured val-ues to reference values was 0.966,87% of them were in the desired range according to ICRP35.
