The radioactive source isn't used for power in smoke detectors, it's used to detect smoke. What small scale devices use radioactivity actually for power?

My grampa had a pacemaker that was.

Edit2: For the smoke detectors, i know its not what powers it per se, as far as the electronics that sound the alarm and such. More pointing out it contains radioactive material, and is something in every (hopefully) house, and you likely walk by it often.
