Полиакриламид по составу основных химических элементов близок к мягким тканям человека, что позволяет его использовать в качестве эквивалента. Волластонит/ГАП был получен методом плазменно-реактивного спекания порошка Ca3(Si3O9) в смеси с реакционноспособными компонентами (CaO и CaHPO4ГАП). Имитация лучевой терапии проводилась на медицинском линейном ускорителе «TRUEBEAM» производства Varian Medical Systems при энергии фотонов 6 мегаэлектрон-вольт (МэВ) с созданием экрана из переносных свинцовых блоков и формированием отверстия в них диаметром 10 мм, через которое происходило облучение. Для регистрации распределения фотонов использовался гамма-спектрометр СКС-50М с детектором на основе сверхчистого германия. Показания приборов суммировались с шагом в 50 килоэлектронвольт (кэВ) в диапазоне от 0 до 2650 кэВ и были представлены в виде графика. В каждом диапазоне проводилось три измерения, после чего вычислялась средняя арифметическая и ошибка средней арифметической. Достоверность различия средних величин определялась по критерию Стьюдента.</p></sec><sec><title>   Результаты</title><p>   Результаты: вторичное излучение на исследуемых образцах в диапазоне 51–100 кэВ составило незначительное различие: волластанит/ГАП 23,18 ± 2,57 импульса/секунду против полиакриламида 21,57 ± 2,37 импульса/секунду с нивелировкой в энергиях 101–150 кэВ – волластанит/ГАП 21,18 ± 2,51 импульса/секунду против полиакриламида 22,9 ± 2,41 импульса/секунду. Однако эти различия не были статистически значимыми.</p></sec><sec><title>   Заключение</title><p>   Заключение: графт микрочастиц волластанит/ГАП является перспективным материалом для точной послеоперационной/предлучевой разметки при планировании лучевой терапии и не требует перерасчета дозы излучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Objective</title><p>   Objective. To determine the potential for generating secondary radiation on a hydroxyapatite-wollastonite graft, which has the potential to be used as a marker for postoperative pre-irradiation marking.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. During the simulation of a radiotherapy session, the spectrum of secondary radiation generated on the hydroxyapatite-wollastonite graft and polyacrylamide was studied. Polyacrylamide, composed of basic chemical elements similar to those in human soft tissues, was used as an equivalent. Hydroxyapatite-wollastonite was obtained by plasma-reactive sintering of Ca3(Si3O9) powder mixed with reactive components (CaO and CaHPO4HAP). The simulation of radiotherapy was conducted using a TrueBeam Linear Accelerator, developed by Varian Medical Systems, utilizing photon energy of 6 mega-electron volts (MeV) with a portable lead block shield and an aperture of 10 mm in diameter for irradiation. An SKS-50M gamma spectrometer with a high-purity germanium detector was used to record the photon distribution. Instrument readings were summarized in increments of 50 kilo-electron volts (keV) within the range of 0 to 2650 keV and presented graphically. Three measurements were taken in each range, after which the arithmetic mean and mean deviation were calculated. The significance of differences between means was determined using Student's t-test.</p></sec><sec><title>   Results</title><p>   Results. The secondary radiation from the studied samples in the range of 51–100 keV showed minor differences: hydroxyapatite-wollastonite produced 23.18 ± 2.57 pulses/second compared to polyacrylamide at 21.57 ± 2.37 pulses/second, while at energies of 101–150 keV, hydroxyapatite-wollastonite yielded 21.18 ± 2.51 pulses/second versus polyacrylamide at 22.9 ± 2.41 pulses/second. However, these differences were not statistically significant.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The graft of hydroxyapatite-wollastonite micro-particles is considered to be a promising material for precise postoperative/pre-irradiation marking during treatment planning and does not require recalculation of radiation dose.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>органосохранное хирургическое лечение</kwd><kwd>вторичное излучение</kwd><kwd>предлучевая разметка</kwd><kwd>лучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>organ-preserving surgical treatment</kwd><kwd>secondary radiation</kwd><kwd>pre-irradiation marking</kwd><kwd>radiation therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют о финансировании проведенного исследования из собственных средств</funding-statement><funding-statement xml:lang="en">The authors declare funding for the study from their own funds.</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">Meattini I, Lambertini M, Desideri I, De Caluwé A, Kaidar-Person O, Livi L.
