Abstract The generation of gaseous 131I is a key technique for building standard reference of gaseous 131I activity concentration. In this study, gaseous iodine (I2) is produced from iodide solution through redox reaction. The production of radioactive gaseous iodine can be adjusted by regulating the activity of the iodide solution in the redox reaction. The productivity of gaseous iodine was determined to be about 78.0% ±7.9% (95% confidence interval) which is relatively stable when using Fe2 (SO4)3 as oxidant under certain reaction condition.
