Sweet Nuclear Phones

The question I'm asking here is with all the radiation and crap already being produced by your trusty phone would you really want a nuclear powered phone. Wouldn't it be better to have a nuclear powered car or some other devices before you start cramming more radiation right next to your brain. Plus, wouldn't you be worried about the possibility of a meltdown in your pants. Now most of you are probably quite used to 'melting down' in your pants but for the normal part of the world this could be a bit of a concern.
