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.

世界上很少有地方生产碘125。在巴西，第一批生产是通过使用位于IPEN核能研究所的IEA-R1核反应堆实现的。为了验证生产的碘125的质量以及诸如碘126，铯134和铯137等污染物的数量，将碘125样品固定在环氧钡基盘中，其几何形状与钡相同。 133参考放射性源，用于校准HPGe检测器。HPGe检测器具有薄的碳复合窗口，可测量27.1至35.4 keV之间的碘125光电峰。这里使用的方法成功地生产和测量了碘125。
