SaphyGATE GN: Advanced Gamma-Neutron Radiation Detector

Developed in collaboration with the French Alternative Energies & Atomic Energy Commission (CEA), the SaphyGATE GN is an advanced gantry monitor that detects Gamma-Neutron radiation without Helium-3 detectors. It meets international safety standards (IEC 62244 & ANSI N42.35) and prevents illegal movements of radioactive sources in critical locations.

The SaphyGATE GN detects both natural and artificial low activity radioactive sources and distinguishes Special Nuclear Materials (SNM) from Naturally Occurring Radioactive Materials (NORM). Its modular design makes it suitable for monitoring vehicles, containers, pedestrians and luggage, and offers exceptional performance in the detection of sealed radioactive sources.
