Abstract

High-energy electron beams are used for especially for radiotherapy of localized superficial tumors. Knowing as accurately as the stopping power and range values is important in electron beam therapy. Electrons beams are preferred in surface treatments due to their characteristic feature. In this work, we have calculated stopping power and range values for incident electrons ranging from 0.1 to 900 MeV range on muscle and skin by using Thomas-Fermi electron density. The obtained data is important in terms of creating a database for such studies.
