Thermoluminescence dating sediments
Scientists in North America first developed thermoluminescence dating of rock minerals in the 1950s and 1960s, and the University of Oxford, England first developed the thermoluminescence dating of fired ceramics in the 1960s and 1970s.
During the 1970s and 1980s scientists at Simon Frasier University, Canada, developed standard thermoluminescence dating procedures used to date sediments.
Next the burial dose rate (D) is determined by measuring the radioactivity in portions of the sample grains and surrounding sediments. Quaternary Science Reviews Ollerhead, Jeff, David J.
Lastly, the age of the sample is determined by dividing the equivalent dose by the burial dose rate (D Journal of Luminescence The Dalhousie Thermally and Optically Stimulated Luminescence and ESR Laboratory The Research Laboratory for Archaeology and the History of Art, Oxford University Aberystwyth Luminescence Dating Laboratory The Sheffield Centre for International Drylands Research (SCIDR), England Center for Applied Dosimetry Archaeometry Research Group Heidelberg, Germany The University of Washington Luminescence Dating Laboratory Aitken, Martin J.
After a brief description of the philosophy of this application, various methods currently in vogue for estimating the accumulated radiation dose in sediments are described.
A brief survey of these results obtained for various sediment types is included so as to demonstrate the range and promise of the TL method for dating Quaternary sediments.
Further investigations are necessary to identify the reasons for regular overestimating of the TL results obtained for loess deposits of the Halych Prydnistrov’ja region.
This fact indicates how this region is unique among the loess areas of SE Poland and NW Ukraine in respect of the conditions of mineral material transport and deposition.
This energy is in constant motion within the minerals or sherds.
Most of the energy escapes as heat, but sometimes this energy separates electrons from the molecules that make up the minerals or ceramics.
They can form the basis for determination of the chronology of changes of palaeoenvironmental conditions.
In this paper we report dating results from the Halych IIC profile (Halych Prydnistrov’ja region, Ukraine).

In 1985, they also developed optically stimulated luminescence dating techniques, which use laser light, to date sediments.
