Sensitive Gamma Probe

The Radiological Detection System (RDS) Sensitive Gamma Probe detects photon (gamma and x-ray) radiation. Its high sensitivity makes it ideal for detecting low levels of radiation. Paired with the RDS Base Unit, the Sensitive Gamma Probe is ideal for search operations to locate gamma radiation sources. The probe measures the exposure rate over a broad range of energies.

Sensitive Gamma Probe Features:

  • Gamma emitters detection & measurement

  • NaI (TI) 1.125 x 1.5 Scintillation detector

  • Sensitive to low levels of gamma radiation

  • Part of the RDS radiation detecting probe family

  • Works with Rad-Extender to download survey data

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

  • Durable, easy-to-use ergonomic design

  • Robust cable connections

  • Smart Probe - can work with any Base Unit - calibration is stored on the probe

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

Sensitive Gamma Probe

As a smart probe, the Sensitive Gamma 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.
