SP122 series plastic scintillators are developed by Hangzhou Shalom EO for low energy γ-ray detection. The substrate of SP122 is our plastic scintillator SP101, a ZnS(Ag) layer are painted on the surface of plastic scintillator SP101, the usual thickness of ZnS(Ag) layer is 8-10mg/cm2 . An advanced and sophisticated processing are used to make the ZnS(Ag) painting, the final scintillators has an excellent homogeneity and uniformity.  SP122 are able to detect γ-ray with energy as low as 40KeV.
