Progress on Metal-loaded Plastic Scintillators for Nuclear Security Applications

摘要

In this paper we report on the fabrication and characterization of tin- and lead-loaded, polystyrene-based plastic scintillators for nuclear security applications. These metal-loaded plastic scintillators have been scaled up to 4 inch diameter sizes and shown to have improved gamma-ray spectroscopy, as well as fast neutron detection and spectroscopy capabilities by means of pulse shape discrimination (PSD).
