Stopping Power Calculations of Electron in Six Types of Human Tissue for Energies (20-20000eV)

Hanin Shaker Hadi, Rashid Owaid Kadhim

Abstract


In this study the electron stopping power was calculated for electron interacted in six types of human tissue (Ovary, testis, Brain(gray/white matter), Lung tissue, Soft tissue, Muscle(skeletal)), in the range of energy (20-20000)  . Losing charged particles energy through interactions due to the penetration of material is very important, especially in the subject of diagnosis and medical treatments. Adopted Curve Fitting Tool and Z. Tan and W. Liu date to the electronic stopping power was calculated for electron and getting the equation for each tissue then we can obtain semi-empirical equation to the electronic stopping power was calculated for electrons in the six mediums studied in this paper .the calculated results were compared through the semi-empirical equation obtained from the source results Z. Tan and W. Liu .After calculating the correlation coefficient CORREL and the standard error STEYX for the results of Semi-empirical equation, the obtained results show a satisfactory agreement.
