2018年全国外照射个人剂量监测能力考核结果与分析

Result discussion of the nationwide ability assessment for personal external exposure dose monitoring in 2018

目的为了维护广大放射工作人员身体健康,提高全国个人剂量监测水平和能力。方法根据考核方案,组织2018年全国个人剂量检测单位进行考核,通过分析考核结果,发现并解决技术服务机构个人剂量监测工作存在的问题。结果参加本次个人剂量能力考核的放射卫生服务机构为345家,其中优秀单位90家,优秀率为26.1%,合格单位(含优秀)322家,合格率93.3%;不合格单位23家,不合格率为6.7%。结论通过多年组织考核,全国个人剂量监测能力持续保持在较高水平。大多数参加考核的单位都能够按照考核方案较好的完成监测能力的考核工作。小部分单位的考核结果与参考值偏离较大,检测报告书写不够规范。不合格单位需要在检测中定期做好质量控制,加强工作人员的培训,进一步提高监测工作的规范性和测量结果的准确度。

Objective To ensure the health and safety of radiation exposure workers and improve personal dose monitoring capability of the national radiological health service institutions. Methods The assessment plan was formulated and conducted. The assessment results were analyzed, in order to find out and solve the problems existing in the personal dose monitoring of service institutions. Results There were 345 effective institutions participating in this personal dose ability assessment, of which 322 were qualified(including excellent ones), so the passing rate was 93.3%. There were 90 excellent institutions, and the excellent rate was 26.1%;There were 23 unqualified institutions, and the unqualified rate was 6.7%.Conclusion Through years of assessment, the national personal dose monitoring capability has remained at a high level.Most of the institutions participating in the assessment were able to complete the assessment of monitoring competence in accordance with the assessment plan. A small number of participating institutions’ assessment results deviated greatly from the reference values. Some test reports were not standardized. It is necessary for these institutions to do quality control in the work, strengthen the training of staff, and further improve the standardization of monitoring work and the accuracy of measurement results.
