FIDLER Probe

The Radiological Detection System (RDS) Field Instrument for the Detection of Low Energy Radiation (FIDLER) Probe is used for low-energy X-ray and gamma radiation detection. The FIDLER Probe detects and distinguishes between low-energy X-rays and gammas. It simultaneously records data over four separate energy windows, by use of a multichannel discriminator. Analysis of this information can enable the detection of materials commonly used in weapons of mass destruction. The FIDLER Probe monitors all four of the following energy windows simultaneously. The Base Unit Home screen has the ability to display one or two energy channels at a time.

• Energy Window 1: 13 – 18 keV

• Energy Window 2: 59 – 60 keV

• Energy Window 3: 143 – 220 keV

• Energy Window 4: 13 – 220 keV

FIDLER Probe Features:

Large gamma NaI(Tl) scintillator
Part of the Rad-Defender radiation detecting probe family
Adjustable handle
Multi-channel discrimination
Simultaneous detection of 4 channels + display of 2 selectable channels
Calibration and firmware upgrades via Rad Defender Data Exchange Console
Common probe connector cable can be used with any Rad Defender probe
Durable, easy-to-use ergonomic design with optional shoulder strap
Robust cable connections
Smart Capability as a smart probe
Designed and tested for military ruggedness to meet both military/defense requirements and industrial applications

As a smart probe, the FIDLER Probe contains a microprocessor and High Voltage circuitry for creating it’s 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.
