Abstract : Illustrative results are given for three types of problems: (1) the transmission of electrons through thin and thick foils, with emphasis on the effect of energy loss straggling; (2) the energy dissipation by electrons in a semi-infinite water phantom, for an incident broad beam (depth dose distribution) and for an incident pencil beam (distribution as function of two spatial variables); and (3) the production of bremsstrahlung in thick targets. The data presented for the first two problems are entirely theoretical and result from a Monte Carlo calculation. Similar calculations for the third problem are compared with recent experiments.
