Most of the energy escapes as heat, but sometimes this energy separates electrons from the molecules that make up the minerals or ceramics.Usually the electrons will reconnect with the molecules, but some will not.

TL has a wide dating range; it has been used to date ceramics from a few hundred years old to geologic formations that are half a million years old.
The technique measures the small amount of energy that continually builds up in the mineral crystal lattice.
This paper reports the first collaboration work between the Physics Department of Rome University «La Sapienza» and the Archaeological Studies Department of Pisa University.
Questo lavoro riferisce sui primi risultati della collaborazione tra il Dipartimento di Fisica dell’Università di Roma «La Sapienza» ed il Dipartimento di Studi Archeologici dell’Università di Pisa ed in esso vengono confrontati i risultati ottenuti con metodi archeologici con quelli provenienti dalla datazione con il metodo della termoluminescenza di vari campioni provenienti dagli scavi.On heating, some of this energy is emitted as visible light.In the majority of cases the pot will have been fired to about 800° C in antiquity when it was made, so that accumulation of stored energy begins anew from that time, and there is the possibility, first suggested by Daniels et al.MOST clays contain a few parts per million of uranium and thorium and a few per cent of potassium, so that the body of an ancient pot receives a radiation dose of the order of 1 r./g/yr., mainly from α-particles.Some of this energy is stored in the constituent minerals of the clay either by the creation of new lattice defects or by the filling of existing impurity traps.Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.
