PAB-2
α and β smear and filter test monitor
The PAB-2 low background counter allows measurement of α and β
surface contaminations. 51 mm diameter smear tests and filters are
controlled and sorted according to the radiological thresholds and
preset uncertainty.
In the absence of samples, the gamma background is measured.
Measuring time is then automatically adjusted according to this
background value and with respect to the detection limit.
PAB-2 is used for testing the contamination on transport casks,
parcels, luggage, materials… leaving a controlled area or a nuclear
site.
