摘要

本文提供了在 VVR-ts 研究反应堆正常运行和生产放射性药物期间，确定受控源排放物中放射性碘同位素的形式和化合物的结果。测定的四种碘同位素 131I、132I、133I 和 135I 的日均体积活度分别为 119、126、36 和 21 Bq/m3。在排放源的气态空气环境中，前三种同位素的 97% 以气态形式存在。在这些气体中，以弱吸附化合物为主。135I 的同位素是在一次实验中确定的，这妨碍了对其在排放物中的形式和化合物得出明确的结论。

Forms and compounds of radioactive iodine in emissions of the JSC Karpov Institute of Physical Chemistry

The paper provides the results of determining forms and compounds of radioactive iodine isotopes in emissions of a controlled source during normal operation of the VVR-ts research reactor and production of radiopharmaceuticals. The determined average daily volumetric activity of four iodine isotopes ¹³¹I, ¹³²I, ¹³³I, and ¹³⁵I equals to 119, 126, 36, and 21 Bq/m³, respectively. A 97-% fraction of the first three isotopes has a gaseous form in the gas-air environment of the emission source. Weakly adsorbed compounds predominate among these gases. The isotope of ¹³⁵I was identified in a single experiment, which hampers drawing unambiguous conclusions about its forms and compounds in the emissions.
