A systematic evaluation of the conventional, condensed history electron transport methodology is performed through comparisons with more accurate single-scatter Monte Carlo calculations. These comparisons highlight the inaccuracies associated with the condensed history method and indicate its range of validity. The condensed history method is used in codes such as MCNP4, SANDYL, ETRAN, ITS, and EGS and requires a number of restrictive assumptions about the scattering characteristics to make tractable the analytical solution to the infinite-medium transport equation.
