Thermoluminescence dating is generally not very accurate.

The accuracy of thermoluminescence dating is only about 15% for a single sample and 7 to 10% for a suite of samples in a single context.

The minerals that are used for thermoluminescence dating are mainly quartz and feldspar.

The last time a crystal was reheated and its electrons were released is known as a "clock resetting event".

This usually occurs when the items are heated to 350 degrees Celsius.

The light is proportional to the amount of radiation absorbed since the material was last heated.Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, some of which are trapped at imperfections in the crystal lattice.Later, heating releases the trapped electrons, producing light.Electron trapping Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, where some are trapped at imperfections.Later heating releases the trapped electrons, producing light whose intensity is proportional to the amount of radiation absorbed.
