Better still, unlike radiocarbon dating, the effect luminescence dating measures increases with time.
The possibility of making use of TL stored in a mineral or pottery sample was first proposed by chemist Farrington Daniels in the 1950s. Applications and limitations of thermoluminescence to date quaternary sediments.
We have 3 fully automated, computer operated Riso Minisys TL readers for measuring the TL.
Sample discs are mounted on a wheel and the readers are programmed to run heating and irradiation sequences.
The TL is measured using a sensitive detector called a photomultiplier tube.
The total amount of The samples are heated and the data appears as a graph of TL against temperature, called a glow-curve.
