1. It is the tube's energy that is affecting everything else. Spacing is the key. Tin foil will possibly reduce the interference, but only if grounded properly; but it will also reduce effectiveness of the program, so don't want to do that.
2. Which is more important - your health, or your entertainment and connectivity? Personally, I don't watch TV any longer, or listen to the radio. I leave my cell phone in another room, turned off. I can always get back to missed calls, but I might not be able to get back to missed frequencies.
