International Journal of Academic Health and Medical Research (IJAHMR)   Year: 2020 | Volume: 4 | Issue: 8 | Page No.: 8-13 Total Stopping Power Calculation of Electrons in Blood, Lung, and Soft Tissue in Energy Range (0.01-1000) Mev Rashid O. Kadhim, Zahraa A. Yassin 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 the human body's tissues (blood, lung, and soft tissue) using the relative equation of Bethe- Bloch in a range Electron Energies (0.01-1000) MeV, the current results are compared with E-star program values, and it was found that our results match well with the E-star program values and their correlation coefficient (0.9).
