Background: Reliable estimation of radiation-absorbed dose is necessary to evaluate the benefits and the risks of radiopharmaceuticals used for diagnostic or therapeutic purposes in nuclear medicine. Materiel and Methods: This study included 47 patients treated with iodine-131 for Graves’ disease. A comparative study between Geant4 Monte Carlo simulation and MIRD formalism was carried out to ev...

GEANT4 is a toolkit for simulating the passage of particles though matter, which contains a complete range of functionality including tracking, geometry, physics models, and hits. In this article, an attempt to use GEANT4 Monte Carlo code to watch a double-gap Resistive Plate Chamber's (RPC) response to neutrons is presented. The simulation calculations of the double-gap RPC have been evaluated...

Since its release in 1999, the LHC experiments have been evaluating Geant4 in view of adopting it as a replacement for the obsolescent Geant3 transport MonteCarlo. The ALICE collaboration has decided to perform a detailed physics validation of elementary hadronic processes against experimental data already used in international benchmarks. In one test, proton interactions on different nuclear t...

In the context of critical applications, such as shielding and radiation protection, ensuring the quality of simulation software they depend on is of utmost importance. The assessment of simulation software quality is important not only to determine its adoption in experimental applications, but also to guarantee reproducibility of outcome over time. In this study, we present initial results fr...

The Hadron Kinetic Model is part of the Geant4 Toolkit; it covers the simulation of hadronic interactions in the intermediate energy range. Its role in the context of Geant4 hadronic models is outlined with emphasis on the physics content, and its Object Oriented design is illustrated.

Cosima is the Geant4-based simulator of the medium-energy gamma-ray astronomy library MEGAlib. Within the MEGAlib framework, Cosima is designed to be a simple, fool-proof interface to Geant4 and to enable the simulation of most of the measurement scenarios encountered by X-ray and gamma-ray detectors in space and on Earth.

GEANT4 is a detector simulation toolkit designed for the new generation of High Energy Physics experiments as well as for nuclear physics, astrophysics, medical and space applications and radiation background studies. An overview of its main features is presented, with emphasis on the most recent enhancements and a selection of results from Geant4-based simulations in various experimental envir...
