Определение физико-химических форм йода-131 в выбросах промышленной реакторной установки

Abstract

To improve the system of cleaning of emissions of radioactive substances, aiming to minimize radiation exposure of the industrial reactor unit the study of physical forms and chemical compounds of radioactive iodine to a cascade of filters of a ventilation system. It is shown that the gas-aerosol mixture in the vent system before the gas purification system mainly contains radioactive iodine in the form of gaseous organic compounds. For 131I, the most probable ratio of the volume activity of organic compounds, molecular compounds and iodine aerosols was obtained-98.99%; 0.94% and 0.07% respectively.
