The OLD Laboratory also provides a commercial luminescence dating service and works closely with clients in industry, archaeological organizations, environmental institutes and other academic groups.Located in the basement of Bessey Hall on UNL's City Campus, the Luminescence Geochronology Laboratory specializes in optically-stimulated luminescence (OSL) dating of Quaternary fluvial, eolian, and coastal deposits.This "dark (amber-light only) lab" contains rooms for sample storage, sample preparation, and OSL readers. This lab primarily serves UNL faculty and graduate students, but collaborative research is ongoing with colleagues from other institutions.We presently have a Daybreak TL/OSL Reader and a RISO OSL Reader, and emphasize the single-aliquot regenerative technique. Fieldwork (within Southern England) including in-situ radioactivity measurements, sample collection and travel to and from site can be undertaken at a daily rate of £300 VAT.We are also able to conduct sample collection outside of the UK if the client is willing to cover additional transport, accommodation and subsistence costs.

Following the single-aliquot regenerative (SAR) method of Murray and Wintle (2000), the dose equivalent (De) is calculated by first measuring the natural luminescence of a sample.

The School of Geography and the Environment, in association with the RLAHA Luminescence Dating Laboratory, Research Laboratory for Archaeology and the History of Art, houses a state of the art luminescence dating facility: the Oxford Luminescence Dating Laboratory (OLD).

Optically Stimulated Luminescence (OSL) dating has emerged within the last 20 years as a key Quaternary absolute dating tool, with a wide range of terrestrial and marine applications.

Optical dating techniques employ ubiquitous quartz or feldspar grains to directly date the deposition of sedimentary units.

As such, the optical dating methods allow the systematic chronological evaluation of Quaternary-age sedimentary sequences.

Through geologic time, quartz minerals accumulate a luminescence signal as ionizing radiation excites electrons within parent nuclei in the crystal lattice.
