The work on medieval buildings, combined with an interest in instrumentation, has included collaborative work on the application of infrared thermography to the structural analysis of medieval buildings with Prof. Ian’s research students have worked on various aspects of the application of luminescence to the dating of structures and archaeological deposits.Two recent theses have focused on the application of OSL to the dating of medieval buildings; Sophie Blain (now a postdoc at the University of Liege) investigated the use of brick in early medieval buildings in SE England and Normandy (Dual Ph D with Univ.Radiation Measurement (in press), doi:10.1016/j.radmeas.20 Rasband, W. Research Statement I have been working in the field of luminescence and electron spin resonance (ESR) dosimetry and its application to Earth and Planetary Sciences.Contact Prof Ian Bailiff (email at [email protected]) After reading physics at Sussex University Ian Bailiff joined the Research Laboratory for Archaeology and the History of Art at Oxford as a postgraduate student and subsequently submitted a research MSc on the development of new luminescence dating techniques.Following a further year working on an instrument development project he came to Durham in 1979 as a research assistant on a pottery dating project; following a series of appointments as a Research Fellow he was awarded an SERC Advanced Fellowship, and in 1991 was appointed a Lecturer. He has developed a luminescence dating laboratory with the capability to support both dating and methodological investigation, and his research has included the study of the luminescence properties of minerals, their application to dating and also to radiation dosimetry.These slowly decay over time and the ionizing radiation they produce is absorbed by mineral grains in the sediments such as quartz and potassium feldspar.

Gillian Hutton’s thesis on roads and routeways in County Durham included exploratory work on the dating of road surfaces.

The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried.

Stimulating these mineral grains using either light (blue or green for OSL; infrared for IRSL) or heat (for TL) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral.

Currently the primary materials of interest are sediments from prehistoric sites and ceramic materials from medieval buildings and structures.

Recent work on the dating of brick from medieval buildings of known age has shown that luminescence is capable of providing reliable and accurate results.
