DIY nuke detector patrolling San Francisco Bay {Engadget}

Aug 24th 2006 3:30PM So, a nuke gives off radiation just sitting around, (regardless of the casing?) Anyway, does this detector pick up the radiation through the hull? or would CG have to board every ship in the bay?

Also, the non-tactical boarding of ships with nukes on them is a no win situation it would probably be to close to blow up or sink - also, the initial boarding crew probably would not make it back out.

Please explain.
