INDICATED USE:
low level radiation monitoring

SYSTEM OPERATION:
The system will continuously monitor background levels until the infrared sensor identifies an object. It will then automatically switch to checking the object for radiation caused by contamination until the object is clear of the sensor, at which time the system will return to monitoring background.

DETECTORS:
2 ea. 7866 cm³ (480 in³) plastic scintillation detectors with 0.32 cm (0.13 in.) lead shielding in weathertight housings

AUDIO:
unimorph-type speaker (greater than 68 dB at 61 cm [24 in.])

METER:
15.2 cm (6 in.) arc 1 mA analog type

METER DIAL:
0–25 kcps

CHECKING:
(green LED) indicates vehicle is passing through system

SYSTEM OK:
(green LED) indicates that system is functioning properly

CHANNEL 1:
pushbutton to check the countrate on channel 1

CHANNEL 2:
pushbutton to check the count rate on channel 2

ALARM:
indicated by red LEDs, red flashing lamp, and audible tone (can be internally set from 1–8.5 deviations above background in half-step increments)

AUDIO ACKNOWLEDGE:
pushbutton to silence the audio after an alarm has been indicated

ALARM RESET:
