Abstract

The response of modern, commercial drawing and painting media and papers to proton irradiation has been studied in a set of 180 colour/paper combinations aimed at assessing the potential of PIXE for the characterization of modern artistic materials. In the marks that appeared on some of the materials, during and after irradiation, colour changes have been calculated and used to set the beam current and the fluence limits for safe analysis.
