Beta Contamination Probe

The SB-32 probe for measurement of surface contamination is designed to be used with any CSP™ survey meter or any computer-based system developed within CSP environment. The plastic scintillation detector has a 32 cm2 detection area.

Tag Features

  • Beta surface contamination measurement
  • 32 cm2 Plastic/ZnS Phoswich scintillation detector
  • Calibration via PC software
  • Robust screwed-on grid simple to decontaminate
  • Easy to change scintillator


The SB-32 probe is the ideal tool for direct measurement of beta emitters on glove boxes, small areas and for personal self control, allowing to check worker’s arm in one pass only. Such a well-defined detection area helps to reduce the background noise and improves the Minimal Detectable Activity to better localize contamination spots. The probe body diameter has been reduced to facilitate general handling and reduce the risk of drops.

Entrance grid has been optimized with ideal balance between open area and detector to grid distance to allowing good efficiency and best detector protection. It is hand screwed on the probe body and very easy to remove for decontamination or Aluminum window foil replacement.

Calibration and QA measurements can be performed directly with the probe, without even using any instrument, by connecting the probe to a computer with Canberra™ Smart Probe Software (CSPS™), allowing your instruments to remain deployed in the field. It can also be connected via CSP-COM™ modules to integrate third party system and behave as a contamination sensor sub-assembly.

SB-32 probe can be upgraded (probe’s firmware) via CSPS software, a USB cable and a PC.
