Not if you slap enough lead around it.

Lead will stop the gammas--but you need lots of low-density material (hydrogen, et cetera) to stop the neutrons.

Did either of you see the part of yesterday's 911 special with Jennings where they took some depleted uranium (to mimic enriched uranium) and put it inside what looked like a pipe bomb and put in in a suitcase. Then they transported on train through Europe using the route smugglers are known to use. They then had it crated up with some pillows and shipped overseas to NEW YORK.

NO ONE checked the suitcase while in Europe. In customs at New York Port Authority, they had detectors, but the detectors have to be held within 4 inches of radioactive material to be picked up. (at least that particular material).

This stuff was X-rayed even, and not noticed by customs agents.

From what they showed, it is very, very easy to smuggle in just about anything, unnoticed. What they seem to be more concerned about is not someone smuggling enriched uranium in today. But that they have been doing so over the past 2-4 years.

I'm gonna go take a shower.

a missconception. there are several isotopes that escape even through lead. Radioactive material is hard to hide if you know what it is that you are looking for.
