Just one more thought, although X-Ray machines are heavily shielded
these days, you something be emitting RFI? Years ago, I remember that
we had some equipment in the Sears tower in Chicago that actually
picked up RFI from an electronic drill in an adjacent building.  (I
could be wrong about the drill, but the RFI was coming from some
electronic equipment being used in an adjacent building.
