Abstract

Abstract: To improve monitoring capabilities, China CDC organized individual monitoring intercomparisons, which provincial health institutions participated in from 2022 to 2024. The irradiation schemes and evaluation criteria were designed in accordance with GBZ 207-2016, "Testing criteria of personnel dosimetry performance for external exposure." The Type II (photon) test specified in the standard was selected as the intercomparison type, with Hp(10) as the target quantity. Each institution submitted 21 dosimeters for participation in the intercomparison exercises. Irradiation schemes with various radiation quality and incident angles were randomly assigned to each participant. Out of 580 Pi values, 82.6% (479) were classified as excellent, and 96.9% (562) met the qualification criteria. Four institutions reported 18 unqualified Pi values. These demonstrate the reliable performance of the dosimetry systems. These intercomparisons helped participants identify system deviations and enabled radiation health administrative departments to grasp the capabilities of each institution, thus strengthening the protection of the occupational health of radiological workers.

2022 - 2024年中国省级卫生机构参与个体监测的比较结果

摘要：为提高监测能力，中国疾病预防控制中心于2022 - 2024年组织省级卫生机构参与单项监测比对。照射方案和评价标准按照GBZ 207-2016《人员外照射剂量学性能试验标准》设计。选择标准中规定的II型（光子）测试作为比对类型，以Hp（10）为目标量。每个机构提交了21个剂量计参加相互比较工作。不同辐射质量和入射角的辐照方案被随机分配给每个参与者。在580个Pi值中，82.6%（479个）被评为优秀，96.9%（562个）符合合格标准。4个机构报告了18个不合格的圆周率值。这些证明了剂量测定系统的可靠性能。这些相互比较有助于参与者识别系统偏差，使辐射卫生行政部门能够掌握各机构的能力，从而加强对放射工作人员职业健康的保护。
