Resumo
Few places in the world produce iodine-125. In Brazil, the first production was achieved by using the IEA-R1
nuclear reactor located at Nuclear and Energy Research Institute – IPEN. To verify the quality of iodine-125
produced, and the amount of contaminants such as iodine-126, cesium-134 and caesium-137 among others,
iodine-125 samples were immobilized into epoxy matrix disc, with the same geometry of a barium-133 reference
radioactive source, used to calibrate an HPGe detector. The HPGe detector has a thin carbon composite window,
which allows measure the iodine-125 photopeaks, between 27.1 and 35.4 keV. The method employed here was
successful in producing and measurement of iodine-125.
