Ionizing radiation from natural radioactivity and cosmic rays produces free charge carriers, which are partly stored in the crystal lattice.Since the concentration of the charge carriers increases with time, their numbers and thus the intensity of the luminescence signal can be employed for dating.
The object to be dated is heated in a laboratory until it glows.
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.
Postgraduate students registered for a degree course within a UK university which does not house a luminescence laboratory may be eligible to apply for an award through a joint scheme set up with the Quaternary Research Association (
Likewise, projects central to the Laboratory's research interests may be carried out at a reduced charge.
