Kadhim, Alaa A. Akon Abstract: In this research is to calculate the total stopping power (stot) of electrons which are two parts: Radiative stopping power (srad) and collisional stopping power (scoll) as well as stopping time for components: water (H2O) and kapton (C22H10N2O5) by using the relative Beth-Bloch equation in the range of electron energies (0.01-100) MeV.The present results are compared with values of Estar code.It is found that our results are in good agreement with values of Estar code and the correlation coefficient between them is ( 0.9).
