Nickel 63 has a half life of 100 years. So that means you have safely store these things for 500 years after using them. Yeah, sounds totally fine.
Sounds very similar to the old Soviet pacemakers with radioisotope batteries. After the collapse of the Soviet Union, records about them got lost and so a bunch of people have been buried with pretty radioactive stuff in their chest. I don't think we (as developed societies) are going to take that risk for some phone batteries...
Not unless it's profitable, at least....
Fortunately for us, Nickel 63 decays to plain old Copper 63, which is stable. Science! However too much copper in the diet can be deleterious.
Yes. After a few centuries it will be harmless.
