      Solid Plastic and Liquid Scintillation Materials

       Plastic Scintillators

      Low density, fast and inexpensive characterizes scintillating plastic. All plastic scintillators are sensitive to X-rays, gamma rays, fast neutrons and charged particles. Special formulations are available for thermal neutron detection or with improved X-ray efficiency. Plastic scintillators are the most popular scintillation material for use in calorimeters, time of flight detectors, nuclear gauging and large area contamination monitors.

       Liquid Scintillators

      Liquid scintillators have many applications in neutron and gamma detection. They also provide low-cost alternatives to other scintillators in applications where large volumes are required. Our liquid scintillators are available in bulk or sealed within Bicrocells. Bicrocells are containers, usually made of glass or aluminum.
