Investigation of Interactions Between Low Energy Positrons and DNA Using the Monte-Carlo method

Abstract: Positron Emission Tomography (PET) is the imaging system used to diagnose an illness. Positrons from a radioactive nucleus are injected into the patient. There are few existing papers on the energy loses of positrons especially with low energy in the biological target. So, in this study, the goal was to investigate how low kinetic energy positrons (20eV-10keV) interact with DNA by using the Monte-Carlo simulation. In the simulation, screened Rutherford scattering Formula where Wentzel screening parameter was u… Show more

“…Calculating scattering events requires employing mathematical expressions known as differential cross-sections. These cross-sections describe particles' force, energy, and direction transitions when either driven toward the target or scattered away [18]. The major processes are the elastic scattering of individual atoms.…”
