Abstract:
Objective To analyze and compare the data of Yunnan Center for Disease Control and Preventionin national individual dose monitoring ability assessment for external exposure in 2017—2019 and summarize the assessment experience, and to improve monitoring ability and quality. Methods Ability assessment preparation was carried out according to the requirements of The National Comparison Scheme for Individual Dose Monitoring Ability, and blind samples of individual dosimeters were sent. After the blind samples were measured in the laboratory, the results were judged according to the judgment methods in the Testing Criteria of Personnel Dosimetry Performance for External Exposure (GBZ 207—2016) and the requirements of the assessment scheme. Results In 2017, there was a single-group performance of 0.02-0.08 and a comprehensive performance of 0.06, and the results were judged to be qualified. In 2018, there was asingle-group performance of −0.01 to 0.08 and a comprehensive performance of 0.05, and the results were judged to be excellent. In 2019, there was asingle-group performance of −0.13 to −0.04 and a comprehensive performance of 0.08, and the results were judged to be qualified. Conclusion The individual dose monitoring system in our laboratory runs stably, and the monitoring results are accurate and reliable. The quality control measures are effective and feasible.
