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.
