Abstract

Proton induced X-ray emission using a peltier cooled X-ray detector was used to determine the concentrations of 10 elements in 20 clay pottery samples collected from excavated Buddhist sites of four districts of Telangana and Andhra Pradesh states, India. The provenance (same or different origin) of pottery samples were determined soil samples from corresponding sites with known origin were analyzed for the validation of provenance methodology adopted in this study. For determining accuracy of the proton induced X-ray emission method, two certified reference materials namely SL-1 and soil-7 obtained from International Atomic energy Agency were analyzed. From these analyses, it was observed that both pottery and soil samples under study belong to four different groups.
