某实验室外照射个人剂量盲样比对结果分析

Blind Sample Measurements of Personal External Exposure Dose in a Laboratory

  • 摘要: 目的 通过个人剂量盲样比对检验参比实验室个人剂量监测系统整体技术水平。

    方法 按照《全国放射工作人员个人剂量监测系统比对方案》,某实验室2010年至2012年连续3次参加由中国疾病预防控制中心辐射防护与核医学安全所组织的全国外照射个人剂量监测盲样比对。

    结果 2010年比对实际测量值与约定真值的相对偏差在& #177;18%以内; 2011年和2012年单项性能和综合性能均在& #177;10%以内, 3次盲样比对结果均符合国家相关标准要求。

    结论 该实验室个人剂量监测系统整体技术水平符合国家相关标准要求。

     

    Abstract: Objective To assess the overall technical level of personal dose monitoring system of a laboratory through random blind sample comparison of personal doses.

    Methods According to the National Comparison Protocol for Personal Dose Monitoring System for Radiation Emission Staff, blind samples of personal external exposure doses were collected from radiation emission workers of a laboratory attending three batches of the yearly blind sample examination organized by the National Institute for Radiological Protection, China Center for Disease Control and Prevention from 2010 to 2012.

    Results The relative deviation of the measured values from conventional true values lied within & #177;18% in 2010. Both single unit determination and comprehensive determination lied within & #177;10% in 2011 and 2012. The comparison results were qualified.

    Conclusion The overall technical level of personal dose monitoring system in the laboratory meets the requirements of relevent national standards.
