Stopping Power of Electrons in Bone, Brain Tissues, and Eyes

Abstract

In this research, the ability to stop collision and radiation as well as the total ability to stop electrons was calculated using the relative Bethe-Bloch equation in human tissues (bone, brain, and eyes) in the energy range (0.01-1000) MeV and the equations were programmed using the MATLAB language. The obtained results showed that the collision stopping power is the dominant of radiation from the total stopping power. An appropriate curve instrument was used as two semi-empirical equations with their constants were obtained. The calculated results were compared to the results of the E-Star code and showed good agreement with practical values.
