Abstract:
Objective Based on the “excellent” performance achieved by our institution in the 2024 national intercomparison of monitoring individual dose from external exposure, this paper systematically summarizes key technical elements and optimization experiences in instrument calibration, operational protocols, and data analysis, aiming to provide methodological references and practical support for continuously enhancing the accuracy and reliability of individual dose monitoring. Methods As a participant in the intercomparison activity, our laboratory strictly followed the technical protocol formulated by the Chinese Center for Disease Control and Prevention. Results In the 2024 national intercomparison of monitoring individual dose from external exposure, the measurement results met the criteria of single-group performance \begin{document}$ \left|{P}_{i}\right| $\end{document} ≤ 0.10 and comprehensive performance B2 + S2 ≤ 0.102, and were rated as excellent. Conclusion The accuracy and reliability of monitoring individual dose from external exposure depend on the precision of instrument calibration, standardization of operations, and strictness of quality control. The effectiveness of the above quality control methods has been confirmed by the practice of our laboratory. These methods can be used to ensure the accuracy of measurement results.
