With irradiation planning for electrons the calculation of dose distribution is very complicated because of dispersion of electrons especially in inhomogeneous medium. Using more efficient computers it is possible to calculate the electron distribution also for clinical application with complicated dose calculation programmes. An arithmetical logarithm according to principle of elementary pencil of rays is described and the correspondence of calculation with measurings at a plexiglass phantom is shown.
