Hangzhou Shalom EO has developed the SP121 (Equal to EJ444) series plastic scintillators, which are suitable for both α-ray and β-ray detection. The plastic scintillator SP121 consists of a ZnS(Ag) layer coated on the surface of our plastic scintillator SP102 with the ZnS(Ag) layer thickness typically being 4.5mg/cm2. The plastic scintillator SP102 is for β-ray detection with a peak emission wavelength of 423nm, and the ZnS(Ag) layer is for α-ray detection with peak emission at 450nm. The thickness of the ZnS(Ag) layer is meticulously designed to obtain exactly the desired α-ray absorption. Advanced and sophisticated processing is used to realize ZnS(Ag) coating, which makes the final scintillators have excellent homogeneity and uniformity.
