To protect from emp you need a "faraday cage" it doesn't have to be thick at all. When I was in grad school we protected delicate equipment with a faraday cage made from copper screen (looked just like fly screen). We made a room inside a larger one with every square inch of floor, walls, ceiling and door covered, and then ran a wire from the cage to the water pipe. We didn't do anything elaborate around the door. There was a small gap where the mesh on the door didn't touch the mesh on the frame when the door closed, but we did run a wire from the door mesh to the rest of the mesh so that it would be at the same electrical potential. It apparently worked because the delicate measurments that were made were accepted for publication (of course the stuff may have worked just fine without the cage too)

In reference to needing a metal cage to protect you from emp as you "wear your chip", is this the metal cage you are referring to?
