Here is an idea for a less EMF Keyboard:

Buy this adapter:

Buy a USB Bluetooth receiver and USB Extender cable.
Place the two together in a cardboard box, lined with tin foil, only cables sticking out through small holes.

This effectively disconnects the computer from the keyboard. Only the adapter which is battery powered will power the keyboard and send it's output back to the computer via Bluetooth which happens in the tin foil line box so it doesn't escape.  The keyboard should have much less EMF this way. It won't be 0, because there are still chips running inside of the keyboard, but RF and E fields will be reduced.

The benefit is, you get to keep your favorite wired keyboard. I just wish there was something like this for the mouse.
