Neutron Probe

The Radiological Detection System (RDS) Neutron Probe is designed to detect neutrons in the energy range from 0.025 eV (thermal or slow) neutrons to 15 MeV (fast). The Neutron Probe has advanced solid-state neutron detection capability. The detector is surrounded by a High-Density Polyethylene (HDPE) material that efficiently slows high-energy neutrons down to a detectable level. The rounded shape allows for sensitivity to neutrons coming in from all directions. The orientation plate on the side of the probe is to be used as a positioning aid against flat vertical surfaces.

Neutron Probe Features:

  • Detection of neutron radiation

  • Part of the RDS radiation detecting probe family

  • Advanced solid-state neutron detection capability (no He-3)

  • Detector surrounded by High-Density Polyethylene (HDPE), a material that efficiently slows high-energy neutrons to a detectable level

  • Sensitive to neutrons coming in all directions

  • Calibration and firmware upgrades via the Data Exchange Console

  • Common probe connector cable can be used with any Rad Defender probe

  • Detection range from 0.025eV to 15Mev

  • An orientation plate is included as a positioning aid against flat surfaces

  • Meets ANSI N42.34 standard

  • Robust cable connections

  • Smart Capability as a smart probe

  • Designed and tested for military ruggedness to meet both military/defense requirements and industrial applications

  • Ergonomic handle plus an optional shoulder strap


As a smart probe, the Neutron Probe contains a microprocessor and High Voltage circuitry for creating its own high voltage. No high voltage is transferred across the interface cable. When connected to the Base Unit, the display will show the probe’s image and radiation measurement—the probe’s onboard memory stores the probe type and calibration information.
