FIELD: engineering of devices for measuring dosimetric signal in optically stimulated luminescent dosimetry of ionizing radiations, possible use for increased reliability, precision and trustworthiness of method and measurements performed during its use.
SUBSTANCE: device for measuring dosimetric signal of optically stimulated luminescence includes a light-impenetrable body which contains source of optical stimulation, detector of ionizing radiations, separating optical filter and photo-detector, where detector of ionizing radiations is positioned between source of optical stimulation and dividing optical filter at a distance of 1-2 millimeters from their surfaces, and the source of optical stimulation is made in form of light-emitting diode with Fresnel prism, optical axis of which is perpendicular to detector plane.
EFFECT: simplified structure of device for measuring signal of optically stimulated luminescence, increased precision, increased reliability, increased trustworthiness of dose measurements due to increased efficiency of registration of optically stimulated luminescence.
