The current thread about radios causing havoc with GFCIs and other electrical equipment got me to wondering about something.
There is currently talk that there is a very real danger of terrorists using a nuclear device in this country, either in the immediate future, or in the longer term. Nuclear detonations generate an "EMP" (electromagnetic pulse) that can destroy unprotected electronic equipment for at least hundreds, if not thousands, of miles outside the blast area.
How do you go about protecting equipment from EMP? I've heard that it can be done, but I've never seen anything at all about how to go about actually doing it.
It seems like this is really important to do in any sort of emergency facility, like hospitals and emergency control centers. It's clearly of extreme importance that the radios of emergency responders continue to operate after a nuclear "event." The same applies to the huge amount of medical electronics that ambulances and hospitals rely on to keep people alive.
