Аннотация

The average volume activity of iodine isotopes is determined, and the ratio of the physicochemical forms of iodine isotopes entering the ventilation system of the first loop of the IVV-2M reactor facility before the emission purification system is investigated. New sorption-filtering materials and a new model for the interpretation of the measurement data is used to determine the physicochemical forms of iodine. It is shown that most of the iodine isotopes are represented in the gaseous form as organic compounds and elemental iodine – 29 and 63%, respectively. The aerosol fraction of the iodine isotopes in the experimental samples of the ventilation system air did not exceed 8% on average.
