“…It is known that during hydrogenation the change to metallic structure of the sample occurs, for example, from macrocrystalline to submicrocrystalline in titanium [12], wherein the diffusion of hydrogen in the metal depends on the type of crystal lattice of metal [13], the degree of perfection, the presence of defects and traps [2,5,6]. When using the product under real conditions simultaneous hydrogenation and irradiation occur.…”

“…At the same time, hydrogen plays the main role in the technology of newly created materials [4]. There search into these processes under the conditions of radiation exposure is of particular importance [5][6][7]. In this case, effectively absorbing the energy of radiation exposure, the electronic subsystem of compounds МеН х becomes excited.…”

The results of the study on hydrogen diffusion through the metal membranes in the process of electrolytic hydrogenation and electron irradiation (energy of 40 keV , the current density is from 3 to 30 mA ) have been presented. It has been established that hydrogen release time from the membrane is determined by the parameters of the electron beam and its duration, and depends on the structure and the phase state of the metal membrane. The analysis of the hydrogen release time was done on a mass spectrometer connected to a vacuum chamber containing an electron gun and an electrolytic cell. The hydrogen diffusion coefficients when exposed to an electron beam were 2-3 times higher than under the same conditions without the electron beam irradiation. The results can be used in the technology of manufacturing of new materials with desired properties.

Abstract. The paper represents the investigations concerning the geometrical size effect of hydrogenated zirconium alloys (Zr-1Ni-H) during gamma-ray irradiation on the amount of energy absorbed. The results have shown that the less the cross-sectional dimensions of the sample or product is, the less energy is absorbed. The paper provides theoretical calculations. The zirconium sample with a cross-section of 2.8х2.8 cm absorbs 30-35% of the energy of the incident gamma-ray flow. The increase in the cross-section of a product up to 28 cm leads to the increase in the absorbed energy by more than 2 times. At the same time, the thickness of the product is constant. This effect is explained by the multiple scattering of gamma-rays. It leads to the nonuniform distribution of defects which can accumulate hydrogen and should be considered when developing the analysis methods. These edge effects are confirmed by the measurement of the thermal electromotive force for the samples of zirconium alloys before hydrogenation and gamma-ray irradiation, and after irradiation.
