title: Models of fast-electron penetration.
abstract: We introduce multiple scattering models of charged-particle penetration which are based on the previous analyses of Yang and Perry (Radiat. Res. 115, 26-43, 1988). Our development removes the main limitations of the Fermi-Eyges approach while retaining its considerable potential as a theory which is useful for applied work. We illustrate key predictions with sample calculations that are of particular interest in therapeutic applications, 5-20 MeV electrons incident on water.
