Study of Nuclear Reactions in Therapy of Tumors with Proton Beams

Abstract

This paper presents an assessment of nuclear reaction yields of protons, (Formula presented.) -particles, and neutrons in human tissue-equivalentmaterial in proton therapy using a simulation with Geant 4. In this study, we also check an enhancement of nuclear reactions due to the presence of Bi, Au, (Formula presented.) B, and (Formula presented.) B radiosensitizer nanoparticles. We demonstrate that a proton beam induces a noticeable amount of nuclear reactions in the tissue. Nevertheless, the enhancement of nuclear reaction products due to radiosensitizer nanoparticles is found to be negligible.
