Beta-Photon Probe

The Radiological Detection System (RDS) Beta-Photon Probe detects beta and high energy photons (gamma and x-ray) radiation. The Beta-Photon Probe is part of the RDS probe family and is used with the Base Unit for radiological detection operations. It is designed to be held in the operator’s hand or attached to the Telescoping Probe Handle. The end cap is removable for increased sensitivity to beta radiation and low-energy x-rays. The Beta-Photon Probe uses a common probe cable to attach to the Base Unit where data is stored. Crosshairs on the outside of the probe housing show the center lines of the detectors. The probe has two different detectors for low to high-range dose and dose rate measurements.

Beta-Photon Probe Features:

  • Acts as an extension of the RDS Base Unit detection capability

  • Part of the RDS radiation detecting probe family

  • Compatible with the Telescoping Probe Handle

  • Detects and measures beta and gamma radiation

  • Removable cap for beta detection

  • Uses common probe cable to attach to Base Unit

  • Durable, easy-to-use ergonomic design

  • Robust cable connections

  • 360-degree detection

  • Smart Capability as a smart probe

  • Works with Rad-Extender to download survey data

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

The Beta-Photon Probe is primarily used to extend the detection capabilities of the Base Unit. It is a smart probe containing 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 Beta-Photon Probe’s onboard memory stores the probe type and calibration information.
