The Thermo Scientific™ RadEye™ SPRD-GN Personal Radiation Detector is the first pager-sized PRD that significantly exceeds the original ANSI N42-48 2008 standards for neutron alarms. With outstanding neutron performance and reliable gamma IDs, the RadEye SPRD-GN Personal Radiation Detector may be the only radiation detection tool you will need.


  • Unprecedented size for gamma detection, gamma ID, and neutron detection
  • Single detector enables less complex design, superior field reliability, and reduced size & weight
  • Neutron alarms in <2 seconds and low false alarms exceeding ANSI specifications as well as lithium and He-3 based units
  • Patent pending source-less routines for ID stabilization and outstanding neutron sensitivity
  • Advanced NBR identifies artificial radiation while minimizing false alarms
