Hydrogen accumulation in samples of a palladium and 12Kh18N10T steel at the hydrogen charging by the electrolytic method and hydrogen release from these samples at its electron and X-ray irradiation are studied. Palladium was used as a comparison material (as most efficiently solvent hydrogen known among the simple materials). It is established that a capture effectiveness of hydrogen from an electrolyte (1 M H_2SO_4 at current density is 0.5 A cm^{-2}) for palladium is 3-4 orders more than for steel. The hydrogen yield nonlinearly increases with growing of electron current density and electron energy is more than 40 keV under electron irradiation of saturated palladium and 12Kh18N10T steel samples. About 90% of the hydrogen had removed from hydrogen saturated palladium samples and only 60% from steel under electron beam with energy 40 keV and current density ≈ 20 μA cm^{-2} for 1 h of irradiation. It is necessary to increase the energy of electrons from 40 to 100 keV for the more effective removal of hydrogen.
