You want Tempest class shielding. Except that you won't be able to
buy it under that name or even find out what it's specifications are
unless you are in the military and have a Need To Know.
What you -can- buy is a Faraday Cage. That'll certainly -reduce- the
signal; I don't know if you'd be able to get it down to "no signal"
at 10 feet.
Our heavy duty shielding here is aimed more at magnetic fields than
electric. It's made out of a steel and nickel alloy or something like
that, and it is *very* expensive.
I don't have even close to a high enough security clearance to know what
our our government agents use for signal shielding; the closest I get to
that is that I know one fellow who will say only that "Yes, I used to work
for them, and I can't tell you anything about what I did."
