As an energetic proton beam penetrates intomatter its energy loss rate (stopping power) increases withpenetration depth reaching a maximum value in a regionknown as Bragg peak. The main objective of this study is todetermine the penetration depths of mono- energeticprotons in water using Monte Carlo simulations.. Theoutputs of the simulations were analysed using ROOTanalysis software. Validation of the Monte Carlo model wascarried out by comparing proton ranges in water obtainedwith Geant4 simulations against data obtained from theNIST database. The simulation results were in excellentagreement (within an approximately 0.5% uncertainty) withNIST data.
