EJ-399-08 Liquid Scintillator for use with Plastic scintillator
This new liquid scintillator is specifically intended for use in contact with the special plastic scintillator.
EJ-399-08 comprises the "fast" scintillator in the combination with EJ-299-13 plastic scintillator and has the following unique characteristics:
  • Emission spectrum nearly identical to that of EJ-299-13
  • Fluor system tailored for use in structures with small cross sections
  • Light output similar to that of EJ-299-13
  • High flash point - not considered flammable
The liquid base is based on mineral oil and high molecular weight aromatic solvents.   It exhibits very low chemical toxicity and has almost no odor.
