Optical dating archaeology
The particular advantage of luminescence dating is that the method provides a date for the archaeological artefact or deposit itself, rather than for organic material in assumed association.In the case of OSL sediment dating, suitable material (sand or silt-sized grains of quartz and feldspar) is usually available ubiquitously throughout the site.
Neutron radiation with energies of 40 ke V to greater than 35 Me V has a dose measurement range from 20 mrem to 25 rem.
From photons to aeons – optical dating in earth sciences and archaeology Luminescence dating is an important tool for studying the Quaternary.
Classical luminescence dating dates when a grain of sand was last exposed to sunlight and subsequently buried, enabling researchers to address many questions in areas of Earth and environmental sciences as well as archaeological contexts.
The photons are detected using a photomultiplier tube.
The signal from the tube is then used to calculate the dose that the material had absorbed.
