Its nothing you'd have to worry about.  You could easily find out with just
a spectrum analyzer.

Hi Dan,
         Do you or anyone else have an estimate on how many nanowatts the
average coil puts out in the GHz range? Is fine level of screening really
needed, or is this "swatting gnats with a sledgehammer"?
