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.
Extended Life Plastic keeps your portal functioning at the coldest temperatures.
