Table 1.

Ratios of the collision kermas due to interactions of the first generation of scattered photons calculated for isotropic scattering and for the angular distributions from the Klein-Nishina and Thomson cross sections for incoherent and coherent photon scattering. The values were calculated from Table 3 in [32]. (The 50 kVp and 100 kVp spectra in [32] were the same as those used in [26].)
