Monte Carlo simulation of IECF using Geant4 for neutron radiography [PDF]

مجله علوم و فنون هسته‌ای, 2023
Neutron radiography (NRG) is a non-destructive imaging technique for image generation using neutron radiation. In this paper, feasibility studies of neutron radiography for IECF were performed by Geant4 Monte Carlo code.

Radioactive Decays in Geant4 [PDF]

IEEE Transactions on Nuclear Science, 2013
The simulation of radioactive decays is a common task in Monte-Carlo systems such as Geant4. Usually, a system either uses an approach focusing on the simulations of every individual decay or an approach which simulates a large number of decays with a focus on correct overall statistics. The radioactive decay package presented in this work permits, for

Evaluation of the effects of cavity under bolus using the Monte Carlo algorithm

Fushe yanjiu yu fushe gongyi xuebao, 2021
To investigate the effects of “cavity under bolus” on dose distribution, we compared and analyzed the difference in dose distribution in the water phantom in the presence and absence of cavities using the Geant4 Monte Carlo package.

THE GEANT4-DNA PROJECT

International Journal of Modeling, Simulation, and Scientific Computing, 2010
The Geant4-DNA project proposes to develop an open-source simulation software based and fully included in the general-purpose Geant4 Monte-Carlo simulation toolkit. The main objective of this software is to simulate biological damages induced by ionizing radiations at the cellular and sub-cellular scale.
