Luminescence and ESR Dating

Radiation Exposure Dating Methods:

Absolute dating by electron spin resonance (ESR), thermoluminescence (TL) , and optically stimulated luminescence (OSL) methods is widely applicable in geology, geomorphology, palaeogeography and archaeology. It allows the determination of ages of geological sediments and archaeological objects.

Age range and precision

The age range for pottery and other ceramics covers the entire period in which these materials have been produced. The typical range for burnt stone or sediment is from about 100 to 500,000 years for luminescence dating methods and 1ka to 1000ka for ESR dating. The error limits on the dates obtained are typically in the range of 5 to 10%.

Commercial dating service

For over 15 years the laboratory has undertaken luminescence dating of archaeological materials and sediments on a commercial basis or research basis.

Our standard cost for TL or OSL dating is 650 euro +VAT per sample but prices can vary depending on the nature and number of samples. Including fieldwork and radioactivity measurements, sample collection.

The typical turn-round time for providing a date is circa 2-6 months, although, rapid dating (circa 4-6 weeks or sometimes less, depending on machine time and sample type) using our fast track service can be undertaken.

We are open to suggestions of scientific collaboration as well as applications for funding for joint projects.

Electron Spin Resonance Dating (ESR):

Fossil teeth are a ubiquitous component of prehistoric sites, and as a consequence, ESR dating of tooth enamel is very widely applicable in archaeology and palaeoanthropology. Since publication of the first papers on dating of sites in Israel (Schwarcz et al., 1988; Schwarcz et al., 1989) electron spin resonance (ESR) dating of tooth enamel has been recognized as a useful tool for chronometric dating in the time range beyond the 40 ka limit of radiocarbon and up to at least 2 Ma (Schwarcz et al. 1994)
