Why not? You can replace 1 million regular batteries with a single one of these.
The radioactivity is not a problem, it's well enclosed in the device, and when the device is spent the radioactivity is probably close to background levels.
A landfill is the perfect place to put them and let them decay into passivity.

It depends on how efficient the device is. That said, the problem if 'nuclear waste' is largely created by ourselves. All of that 'nuclear waste' is still useful, we are just too lazy to utilize it.
A good portion of that waste has completely spent its radioactivity. There is a portion of it that is useful as medical isotopes. There is still more that can be put to other uses. We just need to find applications for the waste rather than spend all of our time trying to find a way to store it.
