The PM-Split-GN is a high-throughput gamma/neutron pedestrian monitor to screen people at airports, seaports, border crossings, train stations, high-threat facilities, and critical infrastructure. The extra-wide portal allows multiple people with baggage to walk through the system at the same time, making it ideal for high foot-traffic locations. Its passive split-monitoring technology accurately identifies the source individual—with a nuisance alarm rate of practically zero—while continuing to accommodate the steady flow of surrounding pedestrian traffic.

FEATURES

  • Gamma and neutron detection

  • Precise source location, accurately identifying an individual source even in high pedestrian traffic areas
