Science Director, Dr. Karen Steelman, wins a National Science Foundation grant to build a new plasma oxidation system

  The project, Shumla’s Plasma Oxidation Laboratory: Construction of a Multi-Sample Instrument, was awarded under the National Science Foundation (NSF) Archaeometry grant program, which supports the application of the physical sciences to archaeology research.   Shumla’s Chemistry Laboratory utilizes the plasma oxidation technique to convert organic material in rock painting samples into carbon dioxide, which can be radiocarbon dated using accelerator mass spectrometry (AMS).… Read more »
