Abstract:
Objective To assess the quality of gross α and β radioactivity measurements conducted by radiological health service institutions and disease prevention and control centers in Gansu Province, China, and regulate their measurement methods. Methods The samples were distributed by Gansu Provincial Center for Disease Control and Prevention as the organizer of the inter-comparison through mail. The institutions participated in the inter-comparison carried out the measurements in accordance with national standards, and submitted the inter-comparison reports in the form required by the inter-comparison scheme. Results A total of 13 institutions participated in the 2023 inter-comparison of gross α and β radioactivity measurement capabilities, and all measurement results met the required standards. The absolute Z-scores for gross α inter-comparison ranged from 0 to 1.21, and the absolute Z-scores for gross β inter-comparison ranged from 0.08 to 1.85. The comprehensive scores ranged from 74.5 to 93.0. Conclusion The measurement capacities of the institutions participated in the 2023 inter-comparison showed improvement compared with the previous year. However, 12 institutions participated in the inter-comparison showed issues in data processing, report formatting, and laboratory quality control. It is necessary to strengthen technical training, standardize the measurement procedures, and improve the measurement capabilities and skills to ensure the quality of services.
