Рассмотрены теоретические основы процесса ФИО. Результаты экспериментов с отбором проб из газа со 100 и 40 %-ной относительной влажностью демонстрируют высокую точность метода. Так, различие между концентрациями трития в модельной смеси и экспериментально измеренной величиной составляет 2 - 3 % независимо от исходных параметров исследуемого газа. Предложенный способ по сравнению с барботированием через слой жидкости позволяет оценить динамику изменения концентрации НТО в анализируемом газе. Высокая эффективность улавливания исключает проскок трития, а малая степень разбавления потоков обеспечивает повышенную точность измерения низких концентраций трития.</p></abstract><trans-abstract xml:lang="en"><p>A new method of sampling tritiated vapors (TV) from gas phase is developed on the basis of the phase isotopic exchange (PhIE) of water. Theoretical foundations of the PhIE process are described. Experimental results of gas sampling (100- and 40% relative humidity) demonstrate high accuracy of the method. Thus, the difference between tritium concentrations in the model mixture and experimentally measured value is 2 - 3%, regardless of the initial parameters of the test gas. The proposed method is more informative compared to bubbling through the liquid, and provides tracing changes in TV concentration in the tested gas. High capture performance eliminates the leakage of tritium, whereas a small degree of flow dilution can improve the accuracy of measuring low tritium concentrations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод отбора проб тритированного пара</kwd><kwd>измерение радиоактивности газа</kwd><kwd>фазовый изотопный обмен</kwd><kwd>тритий</kwd><kwd>method of sampling tritiated vapor</kwd><kwd>phase isotopic exchange</kwd><kwd>measurements of gas radioactivity</kwd><kwd>tritium</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ohuchi-Yoshida H., Hatano Y., Kino Y., Kondo Y.
