The amount of light produced is measuered by a photomultiplier.

The result is a glow curve showing the photon emission in function of the heating temperature: 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.

The paleodose is the absorbed dose of natural radiation accumulate by a sample.

This paleodose is determined from the TL signal measured by heating sample at a constant rate.

These give rise to an external dose rate in addition to the one from secondary cosmic rays.
