The research group gave an overview of a long-lasting project on the Prompt Gamma Activation Analysis (PGAA)-based chemical investigations of archaeological polished stone tools from Hungary. Based on 20 years of PGAA measurements, a more than 700 itemed database was subjected to statistical analyses.

This study summarizes the success of PGAA method on two different levels of chemical data interpretation for variable rock types, i.e. material characterization and provenance identification level. The non-destructive PGAA proved to be very effective in the identification of certain lithologies, while for other polished stone tool raw materials it has medium certainty and requires complementing methods.
