These crystalline solids are constantly subjected to ionizing radiation from their environment, which causes some energized electrons to become trapped in defects in the molecular crystal structure.

If the specimen’s sensitivity to ionizing radiation is known, as is the annual influx of radiation experienced by the specimen, the released thermoluminescence can be translated into a specific amount of time since the formation of the crystal structure.

Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired.

When all the components of the radiation filed estimated, then radiation dose is divided per each accumulated year to obtain radiation dose acceptable for the material.

(Atiken, 1985) Researchers argue that thermoluminescence dating offers certain benefits in radiation measurement. The device stores the radiant energy and later releases it in the form of visible or, in some cases, ultraviolet light.
