As radioactive decay can't be stopped, I'm assuming this emits power continuously. Whatever this is used for won't have any On/Off buttons.
- You can probably turn the device off, but you won't save any battery.
- On/off isn't a problem, the batteries continuously produce energy but a mechanical switch can still toggle the connection to the device.
  
  I was wondering would they have over-heating problems, but the energy is so small it can probably be dissipated elsewhere.
