Abstract
In this paper we present a simple method for the calculation of mass stopping power (in MeV cm 2 /g) of protons from 0.5 Mev to 200 MeV energy range in biological human body substances such as water, bone, muscle and tissue. The proposed relations have been described in terms of energy of proton and mean ( ) of atomic number (Z) and atomic weight (A). A fairly good agreement has been found between our simplified values for mass stopping power of protons for water, bone, muscle and tissue and that of Mukherjee calculated values.

Information on stopping power is essential in many fields involving radiation

The stopping power has been used in Monte Carlo simulations of electron transport relevant to electron probe microanalysis [3,4,5]
Summary
Information on stopping power is essential in many fields involving radiation. Their accuracy may critically affect calculations, measurements and interpretation of experiments. Research concerning the stopping power has taken the position of the basic theme in the fields of ion-matter interactions for a long time. The stopping power of the protons, which is directly related to the linear energy transfer, must be well estimated in order to determine the proton dose distribution in the irradiated tissue accurately [1,2]. We propose a method to obtain the mass stopping power for protons at energy (0.5–200 MeV). Results obtained by this procedure are compared with the available data
