Plastic scintillator performance parameters with the substrate, scintillating material and the second solute – shift the difference between the different and the difference. Therefore, the variety of plastic scintillators is varied, the performance parameters vary widely.
The emission spectrum of a plastic scintillator is consistent with the emission spectrum of a scintillating substance, whereas the emission spectrum of a scintillator
different. The emission spectrum of the plastic scintillator coincides with that of the wave-shifting agent when the wave-shifting agent is applied.
The light output of plastic scintillator increases with the increase of scintillation material concentration, reaching the extreme value when mass concentration is 1% ~ 4%. Continue to increase the concentration, but the light output decreases. The addition of mass concentration of 0.01% ~ 0.02% of the wave-shift agent can make a sharp increase in light output.
For a long time heavy fluences heavy charged particles or electron radiation, so that the plastic scintillator damage and thus reduce the light output.
