With a 600 cm² win-
dow but weighing
only 1.5 kg (3.3 Ib),
the AP6A ZnS
scintillation
probe pro-
vides fast
monitoring of
large surfaces, walls
and floors. It has a higher efficiency
than air proportional counters and is
more practical than gas-flow counters
(no counting gas required).
This probe can be matched with
Thermo's portable survey meters, such
as the Electra/Delta series, ASP-2,
E-600, RM-25.
