SP121 series plastic scintillators are used to both α-ray and β-ray detection. A ZnS(Ag) layer are painted on the surface of plastic scintillator SP102 (Generally, the thickness of ZnS(Ag) layer is 4.5mg/cm2 ). SP102 is for β-ray detection, and ZnS(Ag) layer is for α-ray detection, and the designed thickness of ZnS(Ag) layer are selected to absorb α-ray just exactly. An advanced and sophisticated processing are used to make the ZnS(Ag) painting, the final products has an excellent homogeneity and uniformity.
