2010年放射人员个人剂量监测系统比对结果分析及不确定度评定

Analysis for the results of individual radiation dosage surveillance in staff involved in radiation emission in 2010 and its uncertainty evaluation

目的检验个人剂量监测技术水平,保证监测质量。方法按照"2010年全国放射工作人员个人剂量监测系统比对方案"要求,完成参比剂量计准备、寄往组织者、测量参比剂量计和报送比对结果。结果 3组比对结果单组判定和综合性判定均合格,并合理地评定了比对结果的不确定度。结论该实验室个人剂量监测系统的技术水平符合国家有关标准的要求。

Objective To examine technical level of individual radiation dosage to guarantee its quality.Methods According to the requirements of ＂the national comparison protocol for individual dosage surveillance system in radiation emission staff＂,the reference dosimeter was prepared and then sent to the organizer of surveillance system and determined,and the reported results were compared in the laboratory of Beijing Municipal Center for Disease Control and Prevention.Results Both single unit determination and comprehensive determination of comparison results of the reference dosimeters between three groups was qualified and their uncertainty were evaluated reasonably.Conclusion Technical level of the surveillance system of individual radiation emission dosage in this laboratory meets the requirements of the national related standards.
