Theoretical study of Energy loss of proton in human tissues

Abstract

Charged particles lose energy by nuclear interactions through travelling in matter are very important and very useful especially in nuclear therapy. Using Bethe and Ziegler equation and Srim, Pstar Programs, we calculate, the proton stopping power in tissue by considering the tissue as composed of 9 elements; the proton stopping powers were calculated for those elements for the energy interval 1 - 10 MeV. In addition the proton stopping power for Breast and Lung tissues are evaluated too. Results are presented and compared with the latest published data .
