Evaluating Electron Radiation Stopping Power in Selected Human Tissues Using the Berger-Seltzer Formalism

Abstract

This research investigates the radiation-stopping power of electrons in various human tissues, including adipose tissue, blood, dense bone, brain, eye lens, lung, skin, breast, and muscle, within the energy range of 1 MeV to 1000 MeV. Understanding the energy loss of charged particles as they pass through matter is crucial in medical physics. The data was collected from the International Committee for Radiological Units (ICRU), and total radiation stopping powers were calculated using Berger-Seltzer's famous equation. Then, the total stopping power value in human tissues has been compared with the Universal program code (E-star).  Furthermore, the outcomes of the stopping power vs energy have been presented graphically. Good agreement is found between the gained and the E-star results and varies almost linearly with energy up to 600 MeV.
