Energy loss of light ions, such as alpha particles, has measured in human Bones with a different energy, are very important and very useful especially in nuclear therapy and radiation protection. Using SRIM Computer Programs to calculate the stopping power in bones by considering the tissue mostly composed of 7 elements, the alpha stopping powers and Range were calculated for those elements with the energy interval (0.1–4.5) MeV. In addition, the Results of stopping power for alpha in Bones tissues are presented and compared with the latest published data
