Mini-Rad D radiation detector

Radiation Detection System Design

VPI has developed a rugged, field-ready line of equipment designed for accurate radiation detection and identification.  First responders use such products to find potential threats such as dirty bomb materials, nuclear device components, and toxic environments. 

That line of radiation detection and identification products use the following technologies:

  • Sodium Iodide (NaI) detectors
  • Cesium Iodide (CsI) detectors
  • Cadmium Zinc Telluride (CZT) detectors
  • Photodiodes
  • Photomultiplier tubes (PMT) light sensors
  • Helium-3 (He-3) detectors
  • Solid-state neutron detectors
  • Geiger-Mueller (GM) tube detectors

Rad-DX and iPad

Uses for these radiation detection systems range from:

  • Medical/nuclear medicine monitoring systems
  • Medical waste monitoring
  • Security systems
  • Nuclear material tampering detection systems
  • First responders, firefighters, police personal radiation detection
  • Waste disposal site radiation detection and monitoring
  • Isotope identification
  • Government and military uses
  • Large event security screening
  • Multi-sensor remote monitoring systems
