Geant4

Geant4 serves as a comprehensive toolkit for simulating how particles traverse and interact with various materials. Its core strength lies in combining rigorous Monte Carlo simulation methods with powerful visualization capabilities. Users can define precise geometries and select from extensive physics lists to model real-world scenarios. The software then generates not only quantitative data but also dynamic 3D graphics and event displays. These visuals turn abstract particle behavior into clear, actionable insights, making it an indispensable tool for research, education, and industrial applications where understanding complex radiation interactions is critical.
