METHOD OF EXCITING DOSIMETRIC SIGNAL OF OPTICALLY STIMULATED LUMINESCENCE OF IONISING RADIATION DETECTORS BASED ON ALUMINIUM OXIDE

摘要

FIELD: physics.;SUBSTANCE: invention can be used to increase reliability and accuracy of a method and measurements taken using said method. The method of exciting a dosimetric signal of optically stimulated luminescence of ionising radiation detectors based on aluminium oxide involves putting a detector into an opaque housing between a optical stimulation source made in form of a light-emitting diode and a dividing optical filter at a distance of 1-2 mm from their surfaces inside the said housing. Stimulation is carried out in 30-50 seconds using radiation from the light-emitting diode with a continuous spectrum in the 450-900 nm range.;EFFECT: shorter reading time, high sensitivity, accuracy and reliability of measuring doses, and effective destruction of dosimetric traps in TLD-500K detectors before their use in thermoluminescent dosimetry which replaces thermal treatment of detectors.;8 dwg
