i live in Copenhagen, Denmark and we got preatty good equipment to detect radiation from ships passing through the waters between denmark and sweeden.
i know as for a fact, that the transportation of nuclear devises during the cuba crisis in the '60 was detected.
i shouldnt see anny reasons why this technic isnt implemented by the US army -satelites, ground based equipment etc, and i believe you should need extreme amounts of shelter to 'hide' annything bigger than a back packer sized nuclear devise nowadays (that is, more than just a container, and an entire ship seems a bit unrealistic to line with lead/iron, without it raising suspision).
