Наибольшее распространение получили литий-силикатные стекла, обогащенные изотопом 6Li, которые используются для регистрации тепловых нейтронов. Вместе с тем в силу специфики энергетической зависимости сечения нейтронов легких ядер такие материалы малопригодны для регистрации эпитермальных и более высокоэнергетичных нейтронов. Использование редкоземельных элементов в составе стекол позволяет повысить чувствительность к нейтронам. В системе BaO–Gd2O3–SiO2 при активации ионами церия впервые создано сцинтилляционное стекло с выходом не менее 2500 фот/МэВ, что позволяет создавать недорогие детекторные элементы значительного объема для регистрации нейтронов. Установлено, что детекторы на основе стекла BaO–Gd2O3–SiO2 обладают удовлетворительными детекторными свойствами при регистрации нейтронов в широком спектре их энергий.</p></abstract><trans-abstract xml:lang="en"><p>Inorganic scintillation glasses form a domain of rapidly evolving detector materials used to measure various types of ionizing radiation. The most widespread are lithium-silicate glasses enriched with the 6Li isotope, which are used to register thermal neutrons. At the same time, due to the specificity of the energy dependence of the neutron cross-section of light nuclei, such materials are of little use for the evaluation of epithermal and more highly energetic neutrons. The use of rare earth elements in the composition of glasses makes it possible to increase the sensitivity to neutrons. In the BaO–Gd2O3–SiO2 system, doped with Ce ions, a scintillation glass with a yield of at least 2500 photons / MeV was created for the first time, which permits to create inexpensive detector elements of a significant volume for registering neutrons. It has been shown that a detector based on BaO–Gd2O3–SiO2 glass has satisfactory properties when detecting neutrons in a wide spectrum of their energies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сцинтиллятор</kwd><kwd>стекло</kwd><kwd>световыход</kwd><kwd>гадолиний</kwd><kwd>нейтрон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scintillator</kwd><kwd>glass</kwd><kwd>light yield</kwd><kwd>gadolinium</kwd><kwd>neutron</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">Lecoq, P.
