Thermoluminescence dating TL is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated lava , ceramics or exposed to sunlight sediments. As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating. Sediments are more expensive to date. It will often work well with stones that have been heated by fire. The clay core of bronze sculptures made by lost wax casting can also be tested.

The founders of this nation knew that regardless of the form of government, those in power may become corrupt and seek to rule as the British did by trying to disarm the populace of the colonies.

Thermoluminescence dating presupposes a "zeroing" event in the history of the material, either heating in the case of pottery or lava or exposure to sunlight in the case of sedimentsthat removes the pre-existing trapped electrons. Therefore, at that point the thermoluminescence signal is zero. As time goes on, the ionizing radiation field around the material causes the trapped electrons to accumulate Figure 2.

In the laboratory, the accumulated radiation dose can be measured, but this by itself is insufficient to determine the time since the zeroing event.

The Radiation Dose Rate - the dose accumulated per year-must be determined first. This is commonly done by measurement of the alpha radioactivity the uranium and thorium content and the potassium content K is a beta and gamma emitter of the sample material. Often the gamma radiation field at the position of the sample material is measured, or it may be calculated from the alpha radioactivity and potassium content of the sample environment, and the cosmic ray dose is added in.

Once all components of the radiation field are determined, the accumulated dose from the thermoluminescence measurements is divided by the dose accumulating each year, to obtain the years since the zeroing event. Thermoluminescence dating is used for material where radiocarbon dating is not available, like sediments.

Its use is now common in the authentication of old ceramic wares, for which it gives the approximate date of the last firing. An example of this can be seen in Rink and Bartoll, Thermoluminescence dating was modified for use as a passive sand migration analysis tool by Keizars, et al.

Optically stimulated luminescence dating is a related measurement method which replaces heating with exposure to intense light. The sample material is illuminated with a very bright source of green or blue light for quartz or infrared light for potassium feldspars.
