NMR combating terrorists

I've heard enough of this terrorists stuff on the radio & TV talk
shows. This has been the 3rd show I've heard in the last few weeks
just on radio alone. It now seems almost all the experts investigating
this field say that it is only a matter of time when a terrorist
imports a nuclear bomb or dirty bomb into the U.S. or other countries
and lights it off. What about NMR? After studying it a little it
seems very possible to build a sensitive machine that can detect
uranium and other atoms. I have no idea what materials they can use
for an effective nuclear bomb. How difficult would it be to build such
a machine where the individual stands on a certain spot and the machine
scans for any atoms such as uranium? According to a NMR table, Uranium
receptivity is about a million times less than hydrogen. I guess that
means the EM signal from uranium is about a million times weaker than
hydrogen. Is it still possible if the electronics is sensitive enough?
Perhaps if the device is inside a shielded area such as a faraday
cage.

Any thoughts are greatly appreciated ... especially if it's your child
or grand child that your input might one day help save from a nuclear
fall out.
