DnD-Portal™ user profile
•Unassisted, automatic drive/walk-through measurement for
DnD-Portal™ user triggered by light barriers
DnD-Portal™ operator profile
•Status of walk/drive-through measurement indicated by lights
on the monitor
•Detailed measurement and speed-test results on work station
screen
•In-depth analysis results available instantaneous on work
station
DnD-Portal™ automatic measurement routines
•Background updated every second (while monitor is
unoccupied) for each detector for automatic background
subtraction (100 ms for vehicle version)
•Background count rate monitoring with min. and max. alarm
thresholds

DnD-Portal™ measurement process
•Detect person/car/truck via light barrier on entrance and exit
for measurement start/end denition
•Calculate alarm level from count rates from detector
•Return to “ready for measurement” on clean results
•Alarm operator and display graphics to identify the
radioactive source on the body/car/truck
•Prepare individual results for all detectors available for
operator via detail button on screen
•Store measurement results in database (export to an ASCII/
CSV le enabled)
•Full intranet access to database with explorer browser using
