Figure 1: WA-2x2TA

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.racted thus giving net vehicle reading.
