Protons are most suitable for treating deeply-seated tumors due to their unique depth dose distribution. The maximum dose of protons is a pronounced peak, called the Bragg peak, with zero dose behind the peak. The objective of radiation therapy with protons is to deliver the dose to the target volume by using this type of distribution. This is achieved with a finite number of Bragg peaks at the depth of the target volume. The location of the peak in terms of depth depends on the energy of the protons. Simulations are used to determine the depth dose distribution of proton beams passing through tissue, so it is important that experimental data agree with the simulation data. In this study, we used the FLUKA computer code to determine the correct position of the Bragg peak for proton beams passing through water, bone and adipose, and the results were compared with experimental data.
