For more information: Example Research: Students have used this lab for a variety of purposes, ranging from dating ceramics from Turkey, dating building sequences at Chavin de Huantar in Peru, to dating depositional sequences of canals in Peru.

In the last 30 years, from 1967 to 1997, the use of luminescence signals from naturally occurring minerals has gone though a major metamorphosis, from thermoluminescence (TL) dating of pottery to optically stimulated luminescence (OSL) dating of sediments.

To test the actual dose rate inside our laboratory room, an investigation combining portable dose rate meter, portable Na I(Tl) gamma spectrometry, and blue-OSL dosimetry using Al: C pellets was made.

Although our measurements show the presence of X-rays as far as 3 m from the sources, the dose rates are below the safety regulation and does not affect the dating of the sample stored in the same room as the radioactive sources.

In 1979 Alan Hogg took over the running of the lab and worked closely with Dr.

Henry Polach (formerly Australian National University) improving the vacuum lines and counting procedures.

This includes sample pretreatment, graphite production, accelerator mass spectrometry (AMS) measurement, associated stable isotope measurements, data handling, and age calculations, but with the main emphasis being on the chemical pretreatment methods. The Waikato Radiocarbon Dating Laboratory was established in 1974 by Prof.Alex Wilson in anticipation of geomorphology and tephrostratigraphy projects looking at landform processes in the Waikato region.The University of Washington Luminescence Dating Laboratory has been involved in luminescence dating research since the mid-1980s.The laboratory, which is part of the Anthropology Department, specializes in archaeological applications and is particularly interested in research projects in which luminescence can solve archaeological problems not accessible by other dating techniques.
