This portal monitor features a full color VGA touch screen. Plastic scintillation detectors cover four quadrants of the human body. Gamma and higher energy beta is detectable. Alarm rate is adjustable, but this portal monitor will detect a Cs-137 source as low as one micro curie. The electronics are all digital, microprocessor controlled. This portal monitor fits into a hard case; the entire package weighs approximately 100 lbs. The case is easily moved via casters and handle. The portal monitor is assembled without tools in less than ten minutes. The portal monitor is user-friendly and requires minimal training. The user has the option of an AC or DC power source. A quick response time of 100 milliseconds allows 500 persons to be processed per hour. An optional vehicle monitor kit is available for this portal monitor.
General: Radiation detection for personnel / pedestrians
Setup: No tools required, approximately ten minutes
Display: Full color VGA, Touch sensitive screen. Full color graphics indicate: Normal operation, Errors, and Alarms. All operating parameters: Detector CPS, High Voltage, Set points available on operator screen.
Sensitivity: Meets FEMA sensitivity requirements of less than 1 uCi Cs-137 source during walk through
Processing Rate: Approximately 500 persons per hour
Detectors: Four Plastic Scintillation detectors, 36” L x 3” W x 1.5” D, placed in four quadrants of the body
Scintillators: W/PMT Detector, 162 cubic inches, each detector is 648 cubic inches
Operating modes and data entry: Walk/Drive-through or timed count. System Constantly measures background and automatically subtracts from each measurement.
Audible commands and alarms: System is pre-programmed with appropriate commands to coincide with operations (i.e. Wait, System not Ready, Ready, Too Fast, See Operator). Commands can be configured.
Person and/or Vehicle Sensor and Counter: Optical sensors automatically sense person or vehicle from entering counting area. Counter automatically counts number of persons or vehicles per day, shift, etc and saves count and time/date of vehicles exceeding alarm set points.
Range: 0-100,000 CPS
Printer/PC Output: RS-232, 9 PIN Connector
Relay Output: Optional dry contact can be configured to operate within alarm set points. Display graphics indicate alarm by changing color of parameter that is alarming.
