We report a novel material for use in
125I 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
125Xe, and latter characterized by gamma spectroscopy. The results indicate that the
124Xe was efficiently converted into
125Xe, the precursor of
125I, and support the activity calculations for a model brachytherapy seed.
