[ RadSafe ] Portal monitors to detect SNM

[Rick Orthen]

Matt--Your excellent question has fell on deaf ears.  It appears that this
list is now populated by less than a half-dozen people who are obsessed with
anything other than radiation protection or health physics.  If you have
questions about wind farms, teratogenic sperm, mythology and such, hang
around.

As far as the cargo portals, unfortunately you'll have to look elsewhere for
an informed response.  Perhaps the manufacturer, SAIC-Exploranium?  And I
would doubt (for obvious security reasons) you'll find anyone willing to
disclose the technical limitations of the portals.

The Department of Homeland Security has installed about 400 portal 
monitors, mostly at seaports, to detect smuggling of HEU, plutonium and 
fission products that could be used for dirty bombs. I gather that there 
are differing assessments of how effective these monitors are. Has anyone 
on this list taken a look at this technology?
