Thermoluminescent (TL) dating is used on non-pottery materials, including burnt flints and stones, calcareous deposits, volcanic lavas, and geological sediments. The development of new TL dosimeters and new detectors for radioactivity measurements has increased the ability to measure accurately the dose rate experienced by the samples today. The new techniques have led to a greater awareness of the effect of changes in the radiation environment of the past. Recognition of the limitations of the TL technique, in particular, with regard to the errors inherent in the large number of measurements which must be made to obtain a TL date, has led to a realistic evaluation of the use of TL in archaeology, involving focusing on problems and periods for which the accuracy attainable (five to eight percent) is adequate. During the last ten years growing emphasis has been placed on dating of older archaeological materials such as flint, stones, and calcite. Within the last two years there has been a ten-fold expansion in the application of TL to the dating of unheated sediments.
