Well, looks like this guy was sold phoney material. Spent fuel, even if it has been allowed to cool for 10 years, is still quite hot (perhaps 10,000 R/hr at 3 feet). A 3 minute exposure at this distance is lethal. There could not possibly be enough shielding in that trunk to allow anyone to carry it around without showing obvious signs of acute exposure.
Looks like another "shiny casing filled with pinball machine parts"
The defector in this article is saying things consistent with Khidr's account. Among other things, the Iraqis were so desperate to get their hands on this sort of stuff that they gladly paid silly money for fraudulent products.
