VEHICLE TRANSIT MONITOR

Model # WA-2x2TA - Drive Through

Model # WA-2x2TB - Stop & Measure([fig] ([fig] WA-2x2TA) FEATURES:

* CAN ALARM AT 7 microR/hr RISE WITHIN
  1 SECOND (A)

* SEES AND CAN ALARM AT 1 microR/hr ABOVE
  BACKGROUND (B)

* WEATHER RESISTANT CASES, ALL OPENINGS 
  COMPLETELY GASKETED

* HIGH SENSITIVITY DETECTORS
  (3X3 SCINTILLATORS)

* DYNAMIC BACKGROUND SUBTRACT

* FAST RATE OF CHANGE DESIGN 

* CONTINUOUS OPERATION: "SET AND
  FORGET" 
  
  

DESCRIPTION: Wall - mounted control / alarm module plus two
post mounted cases each with 3"
diameter x 3" Nal scintillators. Rate of change
electronics with audio and visual alarms. 110 volt, 60 Hz
(optional 220V / 50 Hz) operation for rugged outdoor use
as well as indoors. Model WA-2X2TA is a high sensitivity
Gamma Monitoring system for determining possible radiation
contamination in containers or vehicles on a non-pause basis.
Since the operation of this instrument is based on rate
of change in radiation, it will reliably pick up contamination
as it passes near the monitor. Model WA-2X2TB achieves greater
sensitivity by stop and count approach. This system is designed
to be mounted in a corridor, on a loading dock or at a roadway
station. Background is continually updated and subtracted
thus giving net vehicle reading.
