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 radiation 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 tests can be performed on any material leaving a controlled area or nuclear site. The PAB-2 is used for testing contamination on transport casks, parcels, luggage, etc.
