Radiation qualities were characterised and validated at the fully automated X-ray calibration facility of the Individual Monitoring Service at Helmholtz Zentrum München by using half-value layer and Hp(10) dosimetry approaches specified in the updated ISO 4037:2019 standard. As the ISO 4037 contains a somewhat vague description of the half-value layer procedure, we extended it to be more constrained and thus less subjective in its implementation. We specify both the measurement and data analysis steps performed in order to provide reproducible half-value layer results and compare the results with the Hp(10) dosimetry-based validation approach specified in the ISO 4037 as an alternative for field validation. Finally, we discuss the implications of our results and the extended procedure on validation and the recent changes to the ISO 4037.
在慕尼黑亥姆霍兹中心个人监测服务的全自动X射线校准设施中，通过使用更新后的ISO 4037:2019标准中规定的半值层和Hp(10)剂量测定方法，对辐射质量进行了表征和验证。由于ISO 4037对半值层程序的描述有些模糊，我们对其进行了扩展，使其在实施过程中更具约束性，从而减少主观性。我们详细说明了为提供可重复的半值层结果而执行的测量和数据分析步骤，并将结果与ISO 4037中规定的基于Hp(10)剂量测定的验证方法进行比较，作为现场验证的替代方法。最后，我们讨论了我们的结果和扩展程序对验证的影响以及ISO 4037最近的变化。
