AM-801 Portal Monitor Collapsible and portable

wb Johnson AM-801 MonitorFor Personnel Radiation Detection

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.
