目的通过全国热释光个人剂量测量盲样比对,提高放射性检测水平。方法按照《全国放射工作人员个人剂量监测系统比对方案》和《职业性外照射个人监测规范》标准要求。结果 2009年和2010年两次参加盲样比对,各单组测量值与约定真值的相对偏差均在10%左右。结论呼和浩特市个人剂量测量系统技术水平符合国家相关标准要求。
OBJECTIVE To improve the level of radioactive detection through blind comparison of personal thermometry dose measurement in China. Methods According to the “national radiation workers personal dose monitoring system comparison program” and “occupational external exposure personal monitoring norms” standard requirements. Results In 2009 and 2010, two blind blind comparison tests were conducted. The relative deviation between measured value and agreed true value of each single group was about 10%. Conclusion The technical level of personal dose measuring system in Hohhot meets the requirements of relevant national standards.
