Abstract:

Clculations of stopping power ( STP), and the Range ( R ) of protons over the energy range from (10-2MeV to 103 MeV), for different materials; such as water , bone, muscle and tissue and different energies protons have been done; (in MeV cm2/g), using different programs; STAR and Matlab, the results will be shown for, stopping power vs energy and Range Vs energy with some suitable fitting curves.
The electronic (collisional) stopping power of the target materials can be calculated by applying the continuous slowing down approximation (CSDA) to calculate the path length (Range). The results of STP is found to be depends on the atomic number Z and the Ionization energy I, and increases rapidly at low energies, reaches a maximum and decreases gradually with increasing energy, the result of the STP and R were fitted to a suitable empirical formula using matlab program as shown in the figures.

Keywords:

Interaction, stopping power ( STP ), range (R ), protons, human body parts, water.
