RadRopeTM



Technology Marketing SummaryThis lightweight, portable system can rapidly detect the presence of nuclear materials in sealed containers without the use of harmful x-rays.  Using sensors arrayed linearly and encased in fabric, the RadRopeTM system can be dangled in the 2 to 4 inch gap between stacked shipping containers on a cargo ship by a customs inspector.  As the inspector walks along the top containers, a hand-held PDA shows an alarm when any sensor in the array detects radiation levels above background radiation.

The RadRopeTM system has been beta-tested for the U.S. Coast Guard on ships entering port in Charleston, SC.DescriptionGeiger Muller tubes comprise the sensor nodes strung together and arrayed linearly and encased in fabric to any length.  Analog-to-digital converters attached to each sensor send data to the PDA, or to a CPU.   A user interface receives and displays the data.  The Geiger Muller tubes can be configured to detect both gamma and neutron radiation.

The RadRopeTM system can be used in straight line, a curved line, or an angled line.  For example, the system can be mounted on a frame through which items of interest can be passed.  The length of the RadRopeTM system can be easily customized for different uses.
