a Monte Carlo calculated electron fluence spectra for a 10 MeV broad electron beam at three depths (solid lines: total spectra; dashed lines: primary electrons). b Depth variation of Spencer-Attix (Δ=10 keV) stopping-power ratios, water-to-air, for clinical electron beams as a function of R50. Note the large variation of the electron spectra with depth, resulting in the strong depth dependence of the sw,air values. Adapted from ref. [3]
