| 目的 为保证热释光剂量学实验室提供的监测结果准确可靠,检验热释光剂量测量系统的准确性和稳定性。方法 采用邮寄TLD比对方式,每次比对设2个不同监测点和1个对照点,每点布设1个剂量计(内装6～10个探测器),回收后在各自实验室测量。结果 连续3次参加的双边环境剂量计比对,结果均在7%之内符合,该结果都在比对的允许误差范围。结论 热释光剂量学实验室采用的热释光剂量测量系统及监测方法符合国家和国际标准要求,双方在3次6年的环境剂量计比对中保持了一致性。显示了热释光剂量学实验室在中日双边环境剂量计比对中采用的监测方法、测量仪器的校准重复性、TL剂量计的选择,以及比对结果的处理方法已与国际接轨。 |

| Objective For assuring accuracy and reliability of the monitoring results provided by thermoluminescence dosimetry laboratories,an intercomparison with JCAC was performed for several years so as to inspect the veracity and stability of measurement systems of thermoluminescence dosimetry. Methods The method adopted was sending TLD by post and setting up two different monitoring places and one control place for every time of intercomparison.One dosimeter containing six to ten detectors was placed in each measurement site.The dosimeters were measured by both laboratories after taking back. Results The results of intercomparison for three successive times showed that the consistency rates of these environmental dosimeters were all less than seven percent,i.e.,within the permissible error range. Conclusion The measurement systems of thermoluminescence dosimetry and monitoring methods adopted by these thermoluminescence dosimetry laboratories accord with the requirement of both national and international standards.The consistency has been kept for three times of comparisons in six years.The monitoring methods,the calibration reproducibility of measurement equipments,the selection of TLD and the processing methods fo comparison results adopted in intercomparison of environmental dosimeters with JCAC all reach the international level. |
