I do believe this is a direct contradiction -- a thick covering of lead is going to stop radio waves much better than it will stop the radiation.

Yup.

I don't think there is anything the need to shield in a cell-phone, for example. You are incorrectly assuming the entire bomb would be shielded. Ordinary electronics would not give a bomb away.

Still, the description of how such a bomb would be booby trapped sounds more like wishful thinking than anything AQ has demonstrated they can actually do. It is a big step from truck bombs and SAMs to nukes. Alas it is a much smaller step to bioweapons.

Easily done. run two wires through a small hole in the shield out to a relay triggered by the current to the speaker on the phone. It's now fully shielded and remotely triggerable. Any kid with a high school level of electronics could do it.

Just hope that nobody dials a "wrong number."

Hey, you guys have been very informative, don't stop chatting about how these systems work, the rest of need to know. Although some of it is a bit confusing to one who received a classical education.
