BİYOLOJİK HEDEFLER İÇİN Dmax DEĞERLERİNİN DURDURMA GÜCÜNE BAĞIMLILIĞI

Öz

In this study, the relationship between stopping power and dmax values in the interaction of electrons with brain, breast and eye tissues is discussed. Stopping power values were obtained by using Roothaan-Hartree-Fock electronic charge densities, while dmax values obtained with Monte Carlo based computer code Electron Gamma Shower (EGSnrc). A linear relationship between stopping power and dmax values has been observed; and a function was obtained that connects the dmax values to the stopping power values by the curve fitting method. Thus, dmax values can be obtained easily from stopping power values for various energy values.

STOPPING POWER DEPENDENCE of Dmax VALUES for BIOLOGICAL TARGETS

Abstract

In this study, the relationship between stopping power and dmax values in the interaction of electrons with brain, breast and eye tissues is discussed. Stopping power values were obtained by using Roothaan-Hartree-Fock electronic charge densities, while dmax values obtained with Monte Carlo based computer code Electron Gamma Shower (EGSnrc). A linear relationship between stopping power and dmax values has been observed; and a function was obtained that connects the dmax values to the stopping power values by the curve fitting method. Thus, dmax values can be obtained easily from stopping power values for various energy values.
