Low background α and β double scintillators

The scintillator is made of α scintillating substance and β scintillating substance sprayed on 5-6mm plexiglass plate, and processed by special process. The alpha scintillation substance Zns(Ag) is sprayed on the outer layer and the beta scintillation substance is sprayed on the inner layer. The measurement principle is: due to the small range of alpha particles, when the alpha particles enter the alpha scintillating material, all energy is lost on the Zns(Ag) material, causing scintillation and luminescence, and generating an alpha signal. Due to the strong penetration ability, the β particles pass through the ZnS(Ag) material to enter the β scintillation material and generate a β signal. Since the beta scintillation material is translucent, the flash of the alpha particle passes through the beta scintillation material into the photomultiplier tube, and the beta particle passes through the Zns(Ag) material into the beta scintillation substance to produce a beta flash, which enters the photomultiplier tube to produce a beta signal.

Therefore, the scintillator can be used as a necessary detector for low background α and β measurement.

Size:(φ45-φ150)mm, can also be customized according to the size of user requirements.
