It will emit EMI. You got cable dont you? Big deal. the high amp line is running at 3.3vdc; you got 120vac in the walls. If you are worried about high frequency radio waves in your body, then why dont you worry about low frequency magnetic field waves that are a lot stronger? The reason the touch base lamp switches work, is that they detect the low frequency energy absorbed by your body from the AC wiring in the house. The Gaussian effect is several orders of magnitude higher.
to stop EMI but not air, you just need to build a case out of an iron mesh a.
