      Extended Life PlasticTM

      Plastic scintillator is subject to aging which is evidenced by a pulse height loss of about 2% per year.  Extended Life Plastic™ detector enables radiation portal monitor (RPM) systems to operate with high uptime, low probability of escapes and affordable cost.

      While maintaining constant low energy performance, Saint-Gobain has incorporated a revolutionary barrier film along with the standard wrapping to provide an effective seal against vapor penetration. Prolonged testing in hot, humid conditions followed by a cold temperature soak shows that detectors packaged with the barrier film do not suffer the degradation seen in detectors with only standard wrapping.

       

      Features

      • Sensitivity to gamma rays is unaffected
      • Little to no dimensional change
      • Proven reliability with hygroscopic scintillators    
       

      Specifications

      • PVT Scintillator wrapped in reflector
      • Scintillator sealed against moisture intrusion with Saint-Gobain wrap
      • Outer surface wrapped in light sealing black vinyl
      • Photomultiplier tube (PMT) hermetically sealed to the scintillator
      • Potential solutions include:
        • Field replaceable PMT assemblies that complete the hermetic package
        • Temporary hermetic seals that are removed by the end-user to install proprietary readout packages
