DUAL Detection for Security Market

Gamma and Neutron Detection with ONE Detector

In a revolutionary development in the field of radiation detection, Saint Gobain has developed scintillators that can detect both gamma-rays and neutrons.  These crystals replace Sodium Iodide and high pressured Helium-3 tubes that have been industry reference for the past several years. These dual-detecting crystals enable lighter, efficient, and when needed, more powerful detectors – significant attributes for critical applications like homeland security.

Explore our new solutions: 

  • NaILTM 

    • Most cost-effective solution, versatile for a range of platforms
      Large format with a exceptional PSD [FoM = 3.0]
  • CLLB

    • For compact and high-performance applications
      Outstanding resolution with PHR below 4% @ 662 keV and PSD [FoM = 2.0]

ONE Detector replaces two separate detectors, simplifying overall design and reducing manufacturing cost.


Removal of He3 tubes creates space for a larger more powerful crystal, making the detector up to 3 times more sensitive for extended capability.


Enabling a broad range of systems that are compact, He3 free, lower-cost & spectroscopy capable.
