The aim of the present research is calculation the values of total Stot stopping power which consisted from two parts :radiative SRad , collisional SColl of electrons by employing BetheBloch relativistic formula. All the related equations programmed via MathCad2012 by using the mean ionization potential I value for Beryllium in the energy range of (0.1-10)MeV, the results showing a that the collisional stopping power is the dominate along the energy interval of incident electrons than the radiative stopping power and the by comparing the S tot values of Estar code with present results shows a in excellent agreement in especially in the energies (0.1-3)MeV ,after that, the Bethe-Bloch relativistic formula show some discrepancies, which requires addition another corrections factors to keeps the errors in results small.
