Radiation therapy is a treatment that uses particles to destroy cancer cells, stop their development and preserve the healthy organs around the tumour. A precise treatment requires the implementation of several processes, in particular, the determination of the correct ballistics, thus the effect of the particles on the deposited dose. Indeed, one of the most important steps in this evaluation is to calculate the deposited dose in a water phantom with resolution (20 × 20 × 30) cm3 using four therapeutic particles namely electromagnetic radiation "photons", negatively charged stable elementary particle "electrons", neutral particles "neutrons", and heavy elementary particle with a positive charge "protons" with nominal energies from 2 to 20 MeV with constant steps of 2 MeV were simulated in the first place. In the second place, we calculated the deposited dose of the protons beams for therapeutic energies ranging from 60 to 340 MeV with a beam of 100 000 particles produced by a primary radioactive source using the Monte Carlo simulation platform GEANT4. In our paper, we evaluate the effect of four therapeutic particles in the same environment assuring the accurate computation of delivered dose on the treatment plan and subtracting significant discrepancies in terms of deposited dose between particles.
