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.According to Vishnu Purana - Dwaraka was submerged by the sea right after the death of Lord Krishna.This was regarded as a grandiose metaphor, part of a story filled with great myths. and occurs in the Palitana Plates of Samanta Simhaditya.The radiation causes charge to remain within the grains in structurally unstable "electron traps".The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried.
