Abstract
The results of estimating the activity of the aerosol form and gaseous compounds of iodine isotopes in the ventilation system of the IVV-2M reactor facility are presented. The contribution of aerosol and gaseous forms of iodine to the total volumetric activity was simultaneously determined. Criteria of homogeneity of sorbed iodine compounds are determined on the basis of analysis of the dependence of the activity distribution in the layers of a multilayer filter. The study made it possible to determine the form in which radioactive iodine enters the space above the surface of the coolant of the water-moderated water-cooled pool-type research reactor. It is shown that the volumetric iodine activity in the air of the ventilation system of the reactor facility is generally determined by hardly sorbed gaseous compounds.
