D-Tect - Radiological Detection System (RDS) Alpha-Beta Probe
The Radiological Detection System (RDS) Alpha-Beta Probe is used for the measurement of surface contamination survey meter of both alpha and beta radiation. It has dual detection capability, having both a phosphor scintillator and a zinc sulfide PMT. The probe can discriminate between Alpha and Beta simultaneously. Designed and tested for military ruggedness to meet both military/defense requirements and industrial applications.
The Alpha-Beta Probe 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 the probe is connected to the Base Unit, the display will show the probe’s image and radiation measurements. The Alpha-Beta Probe’s onboard memory stores the probe type and calibration information.
