RE: Shielding for electromagnetic fields

["Neil, David M" <neildm@id.doe.gov>]

I once worked with some sensitive electronic equipment which had been
enclosed in a room-size Faraday cage of copper screen.

A mat of grounded copper screen might be effective; it could be put
under the carpet, out of the way, but it might be pricey.  Then again,
so would enough matting to do the job, probably.

Just a thought.
