Simulation results for the random Gaussian blur model of radiation damage applied to (a, b) a two-dimensional crystal formed of pixelated images of a flea and (c, d) a three-dimensional crystal formed of a pixelated electron-density map for PDB entry 3e4h. In both two and three dimensions, the intensity within a given resolution shell decays exponentially with dose, and the half-dose varies with resolution d approximately as D1/2(d) ∝ dα, with α approaching 2 at low resolutions (large numeric values of resolution). The best-fit values in the near-linear region are α = 1.95 and α = 1.86 in (c) and (d), respectively. Simulation details are given in the supporting information.
