Principles of thermoluminescence dating

Rated 4.49/5 based on 998 customer reviews

At this point, the method seems to be a straightforward concept.

However, problems arise from assuming a uniform radiation dose rate over any significant period of time and assuming that the TMRD resulted from the object or artifact being in a strictly constrained environment identical to that in which it was found.

The amount of light produced is a specific and measurable phenomenon.

If the specimen’s sensitivity to ionizing radiation is known, as is the annual influx of radiation experienced by the specimen, the released thermoluminescence can be translated into a specific amount of time since the formation of the crystal structure.

The complex history of radioactive force on a sample can be difficult to estimate.

This is useful for ceramics, as it determines the date of firing, as well as for lava, or even sediments that were exposed to substantial sunlight.

This is followed by a look at measurement equipment that is employed in determining age and its operation.

Luminescence properties of minerals used in dating are then examined after which procedures used in age calculation are looked at.

Sample collection methods are also reviewed, as well as types of materials that can be dated.

Continuing refinements in both methodology and equipment promise to yield luminescence chronologies with improved accuracy and extended dating range in the future and these are briefly discussed.© 2016 The Author(s).
