Abstract

In this work, conversion coefficients for the operational quantity H'(3;Ω) have been calculated for both mono-energetic photons from 2 keV to 50 MeV for angles of incidence from 0° up to 180° in steps of 15° (to complement ICRU 57) as well as for photon reference radiation qualities (to complement ISO 4037). Finally, parameters necessary to determine the influence of the air density on the conversion coefficients have been determined.

摘要

在这项工作中，已针对能量范围从2 keV至50 MeV的单能光子，以15°为步长计算了入射角从0°到180°时的操作量H'(3;Ω)的转换系数（以补充ICRU 57），以及针对光子参考辐射品质（以补充ISO 4037）。最后，确定了用于确定空气密度对转换系数影响所需的参数。
