Alpha-Beta Radiation Detection Probe

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.

Alpha-Beta Probe Features:

  • Military-grade durability

  • Simultaneous display of alpha and beta

  • Part of the RDS radiation detecting probe family

  • Alpha/Beta/Gamma surface contamination measurement

  • Simple removable protective grate for decontamination

  • Built-in mesh screen for extra protection

  • 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)

  • Complies with ANSI N42.17 using Cs-137 as reference source

  • Data Exchange Console options

  • Comfortable, easy-to-use ergonomic design

  • Robust cable connections


The Alpha-Beta Probe is a smart probe containing a microprocessor and High Voltage circuitry for creating it’s 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.
