In this study, we first investigated the influence of the average excitation energy of water (IW) on the Bragg Peak (BP) location. Second, we used the PHITS code to investigate the Bragg curve of 12C ion beams at energy of 200 MeV/u in three mediums: water, soft tissue, and bone. Third, we examine how secondary particles affect the overall dose. The results indicate that the position of the BP is strongly affected by the average excitation energy of water. The tail dose beyond the BP is generated mainly by secondary fragments of the primary carbon ion beams. In addition, PHITS has been shown to faithfully reproduce the measured Bragg curves Keyphrases: Bragg peak, PHITS code, Simulation Monte Carlo, carbon ion therapy
