Abstract

Abstract: The purpose of this study is dose evaluation induced by Auger electrons emitted from 119 Sb in a tumor and surrounding healthy tissues. Dose evaluation was done by using the MCNP6 code in the tumor and healthy tissue (in thyroid follicles) and the calculated absorbed dose was significant. Most of the Auger electron energy emitted from 119 Sb deposits in the decay position, so the effectiveness of Auger electrons should not be ignored also an accurate target therapy can be planned by them. Highlights: The absorbed dose per Auger electron emitted from 119 Sb are significant. The absorbed dose was calculated in a cylinder phantom with different diameters. Auger electrons emitted from 119 Sb deposit at distance less than 80 μm.
