Abstract:
Objective To determine the effectiveness of quality control measures in the laboratory by participating in the national personal dose monitoring ability assessment, and to improve personal dose monitoring ability and quality. Methods According to the requirements of the National Personal Dose Monitoring Ability Assessment Program and standards, seven groups of personal dosimeter were prepared and irradiated by accurate radiation source as requested, and the dose was measured by the laboratory participating in the assessment. The data were processed, and the uncertainty of the measurement results was evaluated. Results In 2018, the assessment results Hp (10) dose range was 0.68-4.27 mSv, the single group performance deviation was −0.01 to −0.06, and the comprehensive performance deviation was 0.04, and the result was qualified. In 2019, the assessment results Hp (10) dose range was 0.74-8.06 mSv, the single group performance deviation was 0.00 to −0.08, and the comprehensive performance deviation was 0.04, and the result was qualified. In 2020, the assessment results Hp(10) dose range was 0.83-3.93 mSv, the single group performance deviation was −0.01 to −0.10, and the comprehensive performance deviation was 0.06, and the result was excellent. Conclusion The personal dose monitoring system in our laboratory runs smoothly, and the monitoring results are accurate and reliable. The laboratory can issue test reports that meet the requirements of national standards.
