С использованием этих данных была рассчитана эффективность защиты вспомогательного оборудования (переносные контейнеры, экранированные шприцы и др.) и возможные дозы внешнего облучения медицинского персонала в отделении радионуклидной терапии. Показано, что в производственном процессе существуют кратковременные операции, когда источник излучения (контейнер с капсулой с радиофармацевтическими препаратами, шприц с радиофармацевтическими препаратами), находясь вблизи тела медицинского работника, создает значительную мощность дозы. По этой причине годовая индивидуальная доза внешнего облучения медицинского работника может приближаться или превышать 1/3 от значения предела дозы. Расчет ослабления гамма-излучения 131I стационарной защитой показал, что толщина стен и перекрытий из бетона 200–400 мм будет обеспечивать непревышение проектных значений мощностей доз гамма-излучения в воздухе при годовом обороте активности в отделении радионуклидной терапии ~3,3·1012 Бк.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the data that allow calculate the attenuation factors in lead, tungsten and concrete of various thicknesses or the thickness of shielding made of these materials for a given attenuation factor for the spectra of gamma radiation of 131I and 177Lu radionuclides. Using these data the effectiveness of the protection of supporting equipment (portable containers, shielded syringes, etc.) and the possible doses of external radiation of medical personnel in the radionuclide therapy department were calculated. It is shown that there are short-term operations in the production process when a radiation source (container with a capsule with activity, syringe with activity), being near the body of a medical worker, creates a significant dose rate. For this reason the annual individual dose of external exposure of a medical worker can approach or exceed 1/3 of the dose limit. Calculation of the attenuation of 131I gamma radiation by stationary shield showed that the thickness of walls and floors made of concrete 200 – 400 mm will ensure that the permissible values of the dose rates of gamma radiation in the air do not exceed at annual turnover of activity in the radionuclide therapy department of ~ 3.3 · 1012 Bq.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радионуклидная терапия</kwd><kwd>йод-131</kwd><kwd>медицинский персонал</kwd><kwd>защита от гамма-излучения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radionuclide therapy</kwd><kwd>iodine-131</kwd><kwd>medical personnel</kwd><kwd>protection from gamma radiation</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">ICRP.
