摘要

FIELD: physics.;SUBSTANCE: invention relates to a method of treating working substances of solid-state ionising radiation detectors based on thermally stimulated luminescence (TL) and optically stimulated luminescence (OSL) phenomena. The method for thermal-beam treatment of substance of a solid-state ionising radiation detector based on aluminium oxide includes steps of heating material and irradiation thereof in a heated state with photon radiation with power of 1-10 mW in the wavelength range of 200-220 nm for a given time, wherein irradiation of the material in a heated state with photon radiation with said parameters is carried out in two steps, first at 550-590°C for 1-3 minutes and then at 370-400°C for 4-6 minutes.;EFFECT: high accuracy and reliability of dosimetry.;1 tbl, 8 dwg
