Yeah, that’s how the battery works.

Which is why your suggestion of simply recycling copper won’t work. You don’t have copper, you have a radioactive alloy.

Not after 50 or so years. Then it’s just non-radioactive copper.

A half life of 100 years many that after 100 years half of it is copper while the other half is still nickel 63. It does NOT mean that after half that time all of it will be copper

That’s not how radioactive half lives work.
Learn about radioactive decay and what half life means.

There’s radioactive and then there’s radioactive. It beta decays with particles that would only penetrate 5 cm of air or .01 cm of tissue.
You could get a thousand of these batteries, grind them up into a powder, explode them in a crowded place as an improvised dirty bomb…and you would still cause less harm than if you did the same with countless chemicals you can buy at the hardware store.
There are many forms of radiation. Something like this going into a landfill is perfectly safe.
