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

During TL analysis, the sample is reheated by a controlled heating process, so the energy is released in the form of light (thermoluminescence) as the electrons escape.

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

The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.

The accuracy of the linearity in heating sample is crucial to have a precise measure.

The result of this measure is, as described above, a glow curve.
