ABG Pancake Probe

The Radiological Detection System (RDS) ABG Pancake Probe is used for detecting alpha, beta, and gamma radiation. It is designed to be held in the operator’s hand for beta/gamma contamination monitoring work. The probe uses a Geiger-Mueller (GM) Pancake Tube to provide a 15.5 cm2 sensitive detection area in a small and lightweight probe. The unit is supplied with a Detector Protective Cover, a removable ‘clip-on’ thin shield for protecting the front face of the probe. An optional aluminum-clad lead shield is available for performing radiological detection operations in high background radiation areas.

ABG Pancake Probe Features:

  • Small hand-held Geiger-Mueller pancake tube detector for alpha, beta, and gamma radiation

  • Part of the RDS radiation detecting probe family

  • Small, lightweight, and durable probe with a 15.5 cm2 sensitive detection area

  • Removable clip-on protective shield

  • Optional aluminum-clad lead shield

  • Durable, easy-to-use ergonomic design

  • Base Unit to probe connector cable can be used with any RDS probe

  • Hot-swapping Smart Probe technology

  • Calibration resident on probe (does not require a paired Base Unit)

  • Robust cable connections

  • Works with Rad-Extender to download survey data

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

Alpha-Beta-Gamma-Pancake Probe

As a smart probe, the ABG Pancake 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.
