|Title||Calculations Of Stopping Power, And Range Of Electrons Interaction With Different Material And Human Body Parts|
In this work we studied interaction electrons with matter; I calculated the stopping power (in MeV cm2/g) from the theory of Bethe-Bloch formula as giving in the reference, and the Range will be calculated. This has been done for different target materials in biological human body substances such as water, bone, muscle and tissue and different energies electrons. All these calculations were done using different programs; STAR and Matlab, the results will be shown for, stopping power vs energy and Range Vs energy. The stopping power in some biological compounds for electrons was calculated over the energy range from (10-2MeV to 103 MeV). Total stopping power was obtained by summing the electronic (collisional) and radiative stopping power of the target materials, and then employing the continuous slowing down approximation (CSDA) to calculate the path length (Range). The total stopping power is proportional to Z2, Z/A and I, increases rapidly at low energies, reaches a maximum and decreases gradually with increasing energy, the data were fitted to a suitable empirical formula as shown in the figures.
