| Abstract:: |
| Objective To analyze the intercomparision result of personal dose monitoring and gross alpha/beta detection capability between the disease control and prevention institutions at provincial, municpal and county levels during 2022-2024, in order to provide a reference for radiation detection capability and policy making of these institutions in China. Methods Data on personal dose monitoring and gross alpha/beta detection, obtanied from the 2022-2024 radiation detection capability intercomparison between the disease control and prevention institutions at different levels, were recorded. Both the qualification rates (including excellence) and excellence rates of all the institutions at all evels from 2022 to 2024 were analyzed using SPSS 22.0. Results From 2022 to 2024, the number of participating institutions at all levels showed an overall upward trend, increasing from 262 to 430, with particularly notable growth at the municipal level. In the 2024 gross α/β detection capability intercomparison, the non-qualification rate in municipal-level institutions was significantly higher than in county-level institutions (χ2=10.53, P < 0.05). The qualification rate (including excellence) of the municipal-level gross alpha/beta detection in 2022 and 2024 were lower than in 2023(χ2=29.93, P < 0.01). Among all regions, the 2024 personal dose monitoring intercomparison result showed that the qualification rate (including excellence) in East China was higher than in Southwest and Northwest China (χ2=15.62, P <0.01). East China also outperformed Northwest China (χ2=16.21, P <0.01). In the 2022 gross alpha/beta detection capability intercomparison, the qualification rate (including excellent performance) in East China and South China was higher than in Northwest China (χ2=23.76, 11.22,P<0.01). Overall, East China showed relatively higher qualification rate in intercomparison result of both personal dose monitoring and radiation detection (including excellence), while Northwest China showed lower qualification rates (including excellence). Conclusions Although the radiation detection capability of disease control and prevention institutions at all levels has improved in recent years, there are still insufficience of detection capabilities at some municipal- and county-level laboratories and even unbalance between different regionas. Policy support should prioritize underdeveloped areas, such as municipal- and county-level institutions and the Northwest, and enhance the technical proficiency and quality management of laboratory personnel. |
