TL;DR: This Special Report presents a description of Geant4-DNA user applications dedicated to the simulation of track structures (TS) in liquid water and associated physical quantities (e.g., range, stopping power, mean free path…) and shows that the most recent sets of physics models available in Geant 4-DNA enable more accurate simulation of stopping powers, dose point kernels, and W-values in liquidWater.
