OK, to be clear: we're not talking about nuclear radiation here, or even cellphone radiation, for the paranoid.
If you look at the diagram in the link, you can see it only goes for 1-2mm above the button, and obviously not further sideways either because otherwise it wouldn't know which one of the three "buttons" side-by-side you pressed. It doesn't use a lot of power at all (like the tablet does) and it can't be turned off completely (remember you have to hold down the menu button to turn the reader on...)
You can lock the sensors in the preferences. But then you have to use the pen. And the reason your pen doesn't need a battery is because the Wacom tablet generates its own inductive field.
You can turn that off too if you are worried about "radiation", but than you can't do anything with reader anymore
