D-Tect - Rad-D

Rad-D fixed mount radiation detection

Need a fixed-position radiation detection solution? The Rad-D is a fixed-position radiation detector that is used to monitor doorways, driveways, and loading docks. A versatile device, it senses gamma and neutron detection in under a second and can trigger active responses such as halting conveyor belts or lowering a blockade.

A major advantage that the Rad-D has over competeing systems is that it is compact and can be mounted anywhere. Each Rad-D system comes equipped with a Bluetooth wireless link and can support four detectors – operating simultaneously – each up to 150 feet away from the display electronics. The detectors can also be configured as either omni-directional or uni-directional. This ensures that the unit is triggered only by what is directly in front of it, not by what is in the next traffic lane or on a parallel conveyor belt.

Like the MiniRad-D, the Rad-D is extremely user-friendly. It provides the operator with a single digit read on a scale of “1” to a “9” to show the strength of the detected radiation. The Rad-D also shows the actual count of photons or neutrons and automatically calibrates itself to the natural background radiation environment to maximize its detection sensitivity.
