摘要

这项研究利用 X 射线光谱法，探讨了从空气辐射率到辐射防护操作量的转换系数，该方法适用于 ISO 4037-1 规定的 300 keV 以下的窄光束质量。通过采用定制的光谱校正算法与现代碲化镉（CdTe）半导体探测器相结合，我们有效地校正了探测过程造成的光谱失真，确保测量结果更加可靠。这些测量对于达到辐射防护标准至关重要。这项研究还分析了与确定转换系数相关的不确定性来源，从而提高了光子剂量测定的准确性和可重复性。

X-ray spectrometry for calculating conversion coefficients from air kerma to operational quantities in radiation protection.

This study explores the conversion coefficients from air kerma to operational quantities for radiation protection, using x-ray spectrometry for the narrow-beam qualities below 300 keV as defined by ISO 4037-1. By employing custom spectral correction algorithms combined with modern cadmium telluride (CdTe) semiconductor detectors, we effectively corrected spectral distortions caused by detection processes, ensuring more reliable measurements. These measurements are crucial for meeting radiation protection standards. The study also analyses the sources of uncertainty associated with the determination of conversion coefficients, thereby providing improved accuracy and reproducibility in photon dosimetry.

期刊介绍： Journal of Radiological Protection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes: dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments. The journal encourages publication of data and code as well as results.
