    PAB 2 Alpha and Beta radiation measurements from a surface

    PAB-2

    PAB-2 is a contamination smear test monitor designed for Alpha and Beta radiations measurements from a surface.

    The PAB-2 low background counter is designed for measuring alpha and beta contamination from a surface in high gamma background.

    Indirect methods of surface contamination monitoring are used when unsuitable geometry or interference from other radiations prevent direct monitoring and in complement when direct monitoring has shown the presence of radioactive contamination. Measurement test can be operate on any material leaving from a controlled area or nuclear site. The PAB-2 is used for testing the contamination on transport casks, parcels, luggage…

    Dedicated to surface contamination measurements

    • PAB-2 provides the best measurement for surface contamination in real-time with its dual proportional counter, sealed Ar-CO2

    User-Friendly

    • The PAB-2 is ergonomic with a large LCD screen display. It is also compatible with Printer and PC

    Adaptable parameters

    • PAB-2 has adjustable contamination thresholds. Paremeter access can also be restricted by a key for more security

    Adapted to any situation

    • PAB-2 can be brought everywhere, and be used for measurements in a vehicle with its dedicated external power supply with car adapter

    PAB-2 has a sealed Ar-CO2 detector, with a window diameter of 51 mm. It is sensitive to both alpha and beta radiation. Measuring time is then automatically adjusted according to this background value, taking into account the detection limit.

    PAB-2 has a guided aluminium plate for smear tests and filters measurements. It is easy to clean in case of contamination.

    3.840 values can be stored on a flash memory, and then saved on another physical support for further data analysis.

    • Internal battery with charger – 8-hour autonomy
    • External power supply +14.4 VDC1A with car adapter
    • Drawer to accommodate a tray with dimensions ø 56 mm x 3 mm maximum (on request)
