Monte Carlo Simulation-Based Calculations of Complex DNA Damage for Incidents of Environmental Ionizing Radiation Exposure

In this paper, we present a useful Monte Carlo (MC)-based methodology that can be utilized to calculate the absorbed dose and initial levels of complex DNA damage (such as double strand breaks-DSBs) in case an environmental ionizing radiation (IR) exposure incident (REI) i.e., nuclear accident. Our objective is assess doses by isolating only one component total released environment after REI will affect health exposed individual. More specifically, emitted radionuclide 137Cs ground (under individual’s feet). We use merging N-Particle Transport code (MCNP) with Damage Simulation (MCDS) code. The lesions have been estimated through simulations for different surface activities ground-based γ source. energy spectrum secondary electrons typical mammalian cells calculated using MCNP code, then these data are used input MCDS estimation critical types. As realistic application, also Excess Lifetime Cancer Risk (ELCR) eight hypothetical individuals, living zones around Chernobyl Nuclear Power Plant, time periods at days accident 1986. conclude any exposition individual near zone increases risk cancer moderate high grade, connected induction radiation. Generally, our has proven assessing rays-induced population, better understanding long-term effects population IR.
