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".Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.Eventually, we will follow this formula to found out how many years old the sample is: Age (year) = accumulated dose / dose rate per year Thermoluminescence dating can be performed only in a specialized laboratory which will have a chemical section for the treatment of the samples with reagents and a radiation hazard restricted area.

Samples should not be exposed to heat and powdery examples should not be exposed to bright light.

When the sample is heated in the lab, it releases thermoluminescence light.
