The effect of accounting for photoelectron escape in RADDOSE‐3D on the calculated DWD (MGy) values for various sized cubic shaped crystals. In all simulations, the beam has been modelled as Gaussian shaped with energy: 12.4 keV, flux: 5 × 10¹¹ ph/s, FWHM: 20 µm × 20 µm and with a rectangular collimation size of 100 µm × 100 µm, and the crystal has been exposed for 100 s over 360°. The PixelsPerMicron parameter in RADDOSE‐3D has been varied for the x‐dimension of each crystal (between 0.5 and 10 pixels/µm) to account for the diminishing size of the crystal.
