THERMOLUMINESCENT SUBSTANCE Russian patent published in 2018 - IPC C09K11/63 C09K11/54 C09K11/66 C09K11/78 G01T1/11 

FIELD: measuring equipment.

SUBSTANCE: invention relates to dosimetry materials of ionizing radiation and can be used in devices for detecting emissions in the environment, in radiological studies of food products. Thermoluminescent substance has a composition PbCd₂B₆O₁₂: Eu³⁺ and was obtained by the addition of europium oxide Eu₂O₃ in the charge, containing the following components, mass %: PbO – 24.99, CdO – 30.27, H₃BO₃ – 43.71, Eu₂O₃ – 1.03. Charge is subjected to a three-stage annealing in air at temperatures of 200 °C, 400 °C and 600 °C for 10, 20 and 80 hours consequently.

EFFECT: thermoluminescent material obtained is moisture resistant and has a high intensity of thermoluminescence.
