The AAPM Task Group 21 protocol provides tables of ratios of average restricted stopping powers and ratios of mean energy-absorption coefficients for different materials. These values were based on the work of Cunningham and Schulz. We have calculated these quantities for Solid Water (manufactured by RMI), using the same x-ray spectra and method as that used by Cunningham and Schulz. These values should be useful to people who are using Solid Water for high-energy photon calibration.
美国医学物理师协会任务组21协议提供了不同材料的平均受限阻止本领比率表和平均能量吸收系数比率表。这些值基于坎宁安和舒尔茨的工作。我们使用与坎宁安和舒尔茨相同的X射线光谱和方法，计算了固体水（由RMI制造）的这些量。这些值对于使用固体水进行高能光子校准的人应该是有用的。
