Abstract: We report a novel material for use in I-125 brachytherapy that consists of amorphous carbon films grown by ion-beam-assisted deposition and doped with Xe (5 at%) by implantation Samples of these films grown on Si substrates were irradiated with neutrons in a TRIGA-I nuclear reactor for the production Xe-125 and latter characterized by gamma spectroscopy The results indicate that the Xe-124 was efficiently converted into Xe-125 the precursor of I-125 and support the activity calculations for a model brachytherapy seed (C) 2010 Elsevier Ltd All rights reserved
