The PAB-2 contamination controller measures α and β surface contaminationof 51 mm diameter smears, and compares it with the preset radiological contamination thresholds.

If there is no smear, it measures the ambient background and automatically adapts the measurement time to guarantee a constant measurement accuracy.

It is used for non-fixed surface contamination points statutory search of materials, parcels, etc... leaving a controlled area or a nuclear site.

The PAB-2R, a reinforced shielded version, is proposedfor use in high gamma environments.
