FIELD: chemistry.
SUBSTANCE: invention relates to the field of low-temperature dosimetry of X-ray as well as mixed electron and gamma radiation using thermoluminescent sensors-thermoluminophores. Thermoluminophore is proposed based on sodium fluoride, which additionally contains lithium fluoride and scandium fluoride and has a composition (mol % by weight): fluoride scandium 0.08–0.75, lithium fluoride 0.001–0.05, sodium fluoride the rest.
EFFECT: proposed thermoluminophore has a rather intense working peak of TSL at 24 K both under the influence of X-ray and mixed electron and gamma radiation, which requires energetically less costly heating of thermoluminophore, only up to 50–55 K, and reduces the time for reading dosimetric information; proposed thermoluminophore has a luminescence spectrum dominating in the orange-red region, which makes it possible to use it to create dosimetric space-based systems with compact photodiode PIN registration.
