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.
