Proton Irradiation the DNA of Human Cells

Abstract

Proton beam therapy provides favorable physical characteristics to kill cancer cells. It is known that all living organisms contain DNA, so we will simulate the bombardment of dry DNA of human’s body cells by protons. The knowledge of stopping powers is very important especially for ion beam cancer therapy. The simulations first-principles dynamics helps the mostly employed linear description of response theory. The study denotes that DNA has suffered ionization by proton bombarding, which leads to long–lasting harm to human or cancer DNA that empowers us to diagnose the latter and treat it with radiation. Through using Bethe and Ziegler’s equations, and also the SRIM programs, we determine the stopping power of the interaction of proton with human’s DNA at approximate energy of 1 to 2.5 MeV. The human’s DNA components are made of five main elements. All mathematical processes and analysis are achieved using Matlab program. The results are introduced in tables and figures. The researchers have formulated the power equation that denotes the values of stopping power according to the range of energy under investigation.
