Plastic Scintillator for Beta Particles
Description

This is a plastic scintillator with ZnS:Ag applied to one side. The Zinc Sulphide layer is enough to just stop the alpha particles. The beta particles reach the thin plastic scintillator approx 0.25mm thick. The plastic scintillator usually requires just enough thickness to let the weak gamma signals pass.
