| Abstract:: |
| Objective To enhance the capabilities of individual monitoring technology services for external exposure. Methods The intercomparison results of the national individual monitoring for external exposure during 2015-2019 were presented, together with a summary and analysis provided of the main existing problems. Results By 2019, 382 of individual monitoring technology service uints, from 30 provinces, autonomous regions or municipalities, participated in the individual monitoring intercomparisons results, involving disease control and prevention centers, occupational prevention and control institutions, research institutes, universities, nuclear industry, medical institutions, and companies. Except for slightly low in 2017, the pass rate in the other four years was above 90%. The excellence rate increased with the years. Conclusions The capabilities of individual monitoring service units can meet the concerned requirements and provide standardized monitoring report for the period of 2015 to 2019, but with some being unqualified. These service units should carefully analyze and identify the reasons for the failure, standardize the quality control of laboratory, and improve the level of measurement and the ability of data analysis. |
