FIELD: high energy engineering.
SUBSTANCE: invention relates to scintillation technics designed for registration of α-, β-, γ- and X-emissions for use in radiotechnology, dosimetry, in nuclear research, etc. Transparent ceramics is manufactured by adding lithium carbonate in amount 0.7-1.0% to starting yttrium oxide powder followed by hot pressing at 34.0-35.9 MPa and 1200-1300°C. Inorganic scintillator comprises working medium containing forward surface with port to receive ionizing α-, β-, γ- and X-emissions, oppositely located back surface, and two side surfaces. Working medium is made from yttrium oxide-based transparent ceramics obtained as above.
EFFECT: considerably lowered temperature and pressure during hot pressing, reduced pressing time, and improved optical characteristics of inorganic scintillator.
