Gamma spectrometry of iodine-125 produced in IEA-R1 nuclear reator, using HPGe detector and fixation into epoxy matrix disc. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 21-25, 2019, Santos, SP. <b>Proceedings...</b> Rio de Janeiro: Associação Brasileira de Energia Nuclear, 2019. p. 1176-1183. Disponível em: http://repositorio.ipen.br/handle/123456789/30556.http://repositorio.ipen.br/handle/123456789/30556Few places in the world produce iodine-125. In Brazil, the first production happened in nuclear reactor IEA-R1 located at Nuclear and Energy Research Institute – IPEN. To verify the quality of iodine-125 produced, because contaminants as iodine-126, caesium-134 and caesium-137 among others, may be produced in irradiation process, 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.1176-1183openAccesscontaminationgamma spectroscopyhigh-purity ge detectorsiodine 125irradiationquality controlvolatilitybrazilian cnenTexto completo de evento0000-0003-2943-60970000-0002-7303-67200000-0002-3442-68300000-0001-5989-7287https://orcid.org/0000-0002-5054-0799https://orcid.org/0000-0003-2943-6097https://orcid.org/0000-0002-7303-6720https://orcid.org/0000-0002-4448-003Xhttp://orcid.org/0000-0003-1335-8864
