Abstract

The MCNPX (Monte Carlo N-Particle Extended) is a program defined as the simulation using a stochastic system for decision making in an uncertain situation. In this study, general X-ray tube modeling and apply energy-spectrum were compared physical characteristics including the photon fluence, percent depth dose (PDD) and energy-spectrum. For photon fluence, X-ray tube modeling was lower than apply energy-spectrum modeling. For PDD and energy-spectrum, X-ray tube modeling was similar to other modeling. However, simulation time at X-ray tube modeling was higher than other modeling. Consequently, apply energy-spectrum modeling could be useful in terms of simulation time with reliability in MCNPX simulation.
