Abstract:Thermoluminescence dating of archaeological ceramics is a well-established technique. Another instrumental method for measuring the same information (ionizing radiation damage in crystal) is electron spin resonance spectroscopy (ESR), a method which offers the advantages of no temperature dependent background and no erasure of the stored information. This study was conducted to assess the potential of ESR as an archaeologocal dating technique.
Because ESR spectroscopy measure the same effect that thermoluminescence does, it, too has potential use as an archaeological dating technique. The results of ESR measurements of the (Al(,Si)' + O(,O)(DEGREES)) center hyperfine peaks in artificially irradiated quartz powder samples showed that this signal could be detected and analyzed at radiation exposures of archaeological interest (2-9 gray) (200-900 rads) and further, suggested that a linear relationship exists between radiation exposure and ESR peak amplitude in that dose range--the two key criteria for the establishment of a dating technique. The spectrometer operating parameters are given, along with a description of the instrumental difficulties encountered. Other areas for future research are also described.
