SP122 series plastic scintillators are used to low energy γ-ray detection. A ZnS(Ag) layer are painted on the surface of plastic scintillator SP102 (Generally, the thickness of ZnS(Ag) layer is 8-10mg/cm2 ). It can detect the range of γ-ray upto 40KeV.
An advanced and sophisticated processing are used to make the ZnS(Ag) painting, the final products has an excellent homogeneity and uniformity.
