ABSTRACT: In this work, the mass stopping power and range of
protons in biological human body tissues (ovary, lung and breast) were
calculated at the energy ranging from 0.04 MeV to 200 MeV using the MATLAB
Program. The data relating to the densities, average atomic number to mass number and excitation energy for the present tissues
were collected from ICRU Report 46. The
mass stopping power was calculated by the Bethe formula. Moreover, the simple integration (continuous
slowing down approximation) method was employed for calculating protons range
at the tissues. The results of the mass stopping
power versus energy and the range versus energy were presented graphically and the empirical
formulae for calculating the mass stopping power and the ranges were obtained. The
present results for mass stopping powers and
ranges were compared with the results obtained by others. Good agreements were found between them,
especially at the energy ranging from 3 to 200 MeV.
