ABSTRACT: The mass stopping power and range of alpha particles in biological human body tissues (blood, brain, adipose, and bone) were computed using the MATLAB Program at energies ranging from 0.2 MeV to 200 MeV. The Bethe Block formula was used to compute the mass stopping power. Furthermore, the alpha particle ranges at the tissues were calculated using the simple integration (continuous slowing down approximation) method. The results of mass-stopping power versus energy and range versus energy were graphed, and empirical equations for determining mass-stopping power and ranges were derived. The current results for mass-stopping powers and ranges of bone cortical and adipose tissues were compared to those produced by ASTAR results (Alpha Stopping Power and Range). They showed good agreement, especially for energies that extend from 1 to 200 MeV.
