Abstract

For ISO 4037 x-ray matched reference fields, the radiometric quantities of the x-ray fields must be verified to apply the recommended conversion coefficients stated in ISO 4037-3. To ensure the proper applications, ISO 4037 x-ray reference fields must be validated following new operational quantities defined in the ICRU 95 report. For these reasons, in this work, the first and second half-value layers (

H V L

) of ISO 4037 x-ray fields were calculated. Moreover, the conversion coefficients to convert air kerma to the new operational quantities were investigated for ISO 4037 x-ray reference fields with various beam qualities. The maximum deviations from the reference

H V L

values were also deduced, corresponding to 2 % changes in the conversion coefficients. The selection of

H V L_{1}

H V L_{2}

in practical measurements was also discussed.

根据ICRU-95操作数量验证ISO 4037 x射线参考场

对于ISO 4037 x射线匹配参考场，必须验证x射线场的辐射量，以应用ISO 4037-3中规定的推荐转换系数。为了确保正确的应用，ISO 4037 x射线参考场必须按照ICRU 95报告中定义的新操作量进行验证。为此，本文计算了ISO 4037 x射线场的第一和第二半值层（HVL）。此外，还研究了不同光束质量的ISO 4037 x射线参考场将空气克尔玛转换为新操作量的转换系数。推导出了与参考HVL值的最大偏差，对应于转换系数变化2%。讨论了实际测量中HVL1或HVL2的选择。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
