  • Windows 7 Embedded operating system with LAN capability and USB ports
  • Same “industry-best” software and serial bus electronics across Mirion Argos-TPS/AB, Cronos®-1/4 /11, Sirius™-5 and GEM™-5 family; no re-training needed
  • Compliant with IEC61098 Standard requirements
  • Algorithm based on Gaussian or Bayesian statistics (compliant with the ISO 11929:2019 Standard requirements)


The Mirion Argos-PBG family of Whole Body Surface Contamination Monitors provides the ultimate user-friendly operation with thorough and reliable detection of external contamination on personnel working in nuclear environments. Both Argos-5PBG and Argos-3PBG monitors feature our most advanced gasless, Thin Plastic Scintillator (TPS) detectors optimized for the best possible beta/gamma response.

Until recently, the elimination of counting gas has been the only advantage of using of plastic scintillation detectors over traditional gas flow detectors in whole body monitors. The sacrifice for this advantage was in detector performance (low efficiency, bad uniformity) leading to longer count times. Mirion has successfully addressed the challenges of this gasless detector technology, minimizing the trade-off between operating costs and performance.

The Argos-3/-5PBG gasless monitors offer the same industry-best contour geometry as the Argos-3/-5AB gas flow monitors. The need for counting gas is eliminated by using scintillation detectors with an embedded PMT to minimize dead space between detectors. This arrangement provides optimal contour geometry and coverage for the occupant.

All Argos monitors use a sophisticated “fast following” background trending and release-limit algorithm to provide the best performance in a stable or varying radiation field.

With Mirion WebRemote® software, an easy-to-use touch screen graphical user interface for industrial PC-based operation, results in improved health physics programs, better tracking of contamination and faster, more thorough personnel throughput at boundary points.

Excellent detector protection, modularity of components, and extensive diagnostics result in direct reductions in maintenance, repair, and operation costs.
