Abstract

The purpose of this study is dose evaluation induced by Auger electrons emitted from ¹¹⁹Sb 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 ¹¹⁹Sb 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.

Keywords: (119)Sb; Antimony-119; Auger electron; MCNP; Radionuclide therapy.
