“…The lift-andturn device, serving to deliver the subjects to the irradiation zone, can carry up to 6 containers to be measured, each container being rotated during the measurement. To increase the emission detection efficiency in the energy range from 20 to 30 keV, the detection unit with high-purity Ge crystal was used [36].…”

The low values of isotope effects in the sorption/decontamination processes make it possible to investigate the properties of the sorbing and decontaminating agents with the use of stable isotope simulators. In the work present-ed here the element content was determined from the characteristic X-ray emission induced by the proton beam (PIXE), by gamma-ray emission from the radioactive source, and by emission from the X-ray tube. Based on the results of efficiency determination for different kinds of sorbents and decontaminants, recommendations have been given for the choice of materials having the wanted performance characteristics.

Проведено сравнение методик для определения сорбционных свойств адсорбента СКТ-3И с использованием 131 I и 127 I. 127 I определялся в углеродной матрице по характеристическому рентгеновскому излучению К-серии атомов йода, возбуждаемому гамма-излучением с энергией 60 кэВ от радиоактивного источника 241 Am, 131 I определялся по регистрации наведенной гамма-активности с энергией 364 кэВ. Определен коэффициент корреляции для методов, позволяющий утверждать о том, что оба метода дают адекватную оценку сорбционных свойств СКТ-3И. Это дает возможность использовать методику с 127 I для оценки коэффициента очистки сорбентов углеродных фильтров, используемых в системах вентиляции на украинских АЭС. Ключевые слова: вентиляционная система АЭС, йод, углеродный адсорбент, характеристическое рентгеновское излучение.

The material shows the results of using the Geant4 program to simulate the operation and capabilities of the SKIF stand when recording radiation K-series with detector the AXAS-D of stable iodine in activated carbon, which is used for air purification at the NPP. The radiation spectra obtained in different situations are shown: at the entrance and exit of the measuring installation; and their processing. The parameters of the registration system were obtained – efficiency and dependence on the thickness of the detector crystal.
