Установлено, что при хроническом поглощении 3Н Helianthus Annuus корневой системой значения фактора R в ходе вегетации варьируют от 0,11 до 0,27 при среднем значении 0,21. Скорость формирования тритированного органического вещества изменялась в пределах от 0,08 до 0,044% ч-1, с максимумом в фазе облиствления. Индекс транслокации (translocation index - TLI) для культуры Helianthus Annuus при корневом поглощении 3Н составил 65%, что почти в 2,5 раза выше, чем при аэральном поглощении радионуклида. Характер распределениями по органам Helianthus Annuus при длительном корневом поступлении 3Н для трития в свободной воде (ТСВ) уменьшается в ряду «корни &gt; соцветия &gt; стебли &gt; листья», для органически связанного трития (ОСТ) - «соцветия &gt; стебли &gt; листья &gt; корни». При корневом поглощении 3Н культурой Helianthus Annuus значения активности ТСВ тесно коррелируют с активностью радионуклида в воде, поглощаемой корнями (r = 0,89). Установленные закономерности распределения 3Н по органам Helianthus Annuus и значения R имеют практическое значение для биомониторинга тритиевого загрязнения окружающей среды.</p></abstract><trans-abstract xml:lang="en"><p>The paper provides results of quantitative assessment of 3H incorporation by Helianthus Annuus in case of intake through the roots in vitro. It was found, that in case of chronic 3H intake through the roots, R factor value for Helianthus Annuus during vegetation period ranges between 0.11 and 0.27 with the average of 0.21. The rate of generation of triturated organic matter ranges between 0.08 and 0.044% per hour, with the maximum value reached at the leaf formation stage. Translocation index for Helianthus Annuus in case of intake of 3H through the roots is 65%, that is almost 2.5 times higher than for aerial uptake of the radionuclide. Values of 3H distribution among the organs of Helianthus Annuus when continuously received through the roots decreases for tissue free water tritium (TFWT) in the range “roots &gt; flowers &gt; stalks &gt; leafs”, while for organically bound tritium (OBT) these decrease in the range “flowers &gt; stalks &gt; leafs &gt; roots”. When Helianthus Annuus absorbs 3H through the roots TFWT activity values correlate well with activity of the radionuclide in water, absorbed by the roots (г = 0.89). Regularities found in distribution of 3H among the organs of Helianthus Annuus and R values are of practical importance for biomonitoring of contamination of environmental objects with tritium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Helianthus Annuus</kwd><kwd>тритиий</kwd><kwd>инкорпорирование</kwd><kwd>тритий свободной воды тканей</kwd><kwd>органически связанный тритий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helianthus Annuus</kwd><kwd>tritium</kwd><kwd>incorporation</kwd><kwd>tissue free water tritium</kwd><kwd>organically bound tritium</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке Министерства образования и науки Республики Казахстан в рамках научного гранта АР08956713 «Исследование радиационно-гигиенической опасности техногенного трития при его накоплении растениеводческой продукцией для оценки дозовой нагрузки на население»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Weinberg A.
