As an energetic proton beam penetrates into matter its energy loss rate (stopping power) increases with penetration depth reaching a maximum value in a region known as Bragg peak. The main objective of this study is to determine the penetration depths of mono- energetic protons in water using Monte Carlo simulations.. The outputs of the simulations were analysed using ROOT analysis software. Validation of the Monte Carlo model was carried out by comparing proton ranges in water obtained with Geant4 simulations against data obtained from the NIST database. The simulation results were in excellent agreement (within an approximately 0.5% uncertainty) with NIST data.
