Abstract
Radiation-thermal oxidation of beryllium in contact with water at temperatures T = 473…773 K under the combined effect of temperature and gamma radiation has been studied by methods of infrared and optical spectroscopy. The formations of an oxide layer on the surface of beryllium were traced from the infrared and optical reflection spectra. In the IR spectra, the broadening of the oxide layer on the Be surface (T = 573 K) was revealed
with an increase in the absorbed dose by ~ 2.5 times, which is associated with inhomogeneities caused by gamma irradiation. According to the optical reflection spectra of the surface of radiation-thermally oxidized Be, it was revealed that in the region of the edge of short waves λ ≤ 250 nm, an absorption band is observed, the intensity of
which increases with increasing contact time and indicates the formation of an oxide layer
