Abstract:
Objective In order to improve the personal dose monitoring ability of radiation health technical institutions, and standardize the detection methods and procedures. Methods Develop adetailed assessment plan according to GBZ 207—2016 “Testing criteria of personnel dosimetry performance for external exposure”, organize a national assessment of personal dose monitoring capabilities in 2020, analyze the problems arising from the assessment, and strengthen supervision and training in the future. Results A total of 457 institutions participated in this assessment, of which 421 were qualified (including 74 excellent institutions, with an excellent rate of 16.2%), and 36 were unqualified, accounting for 92.1% and 7.9% respectively. Conclusion The number of institutions that participated in the assessment this year reaches a record high, with a passing rate 4.08% higher than that in 2019. The overall monitoring capacity of the country has been greatly improved. However, some institutions still have problems such as irregular symbol writing, unupdated detection standards, and large deviations in testing data. It is necessary to improve the ability of loboratory detection and data analysis, standardize the operation process, and ensure the quality of assessment.
