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.
Can I just store it in the river behind my house?
That's bad for the environment. You have to send them down the garbage disposal first!
I noticed, by reading the article, that Nickel 63 decays to Copper 63 which is stable.
"Betavolt further states the battery is environmentally friendly. “After the decay period, the nickel 63 isotopes become a stable isotope of copper, which is non-radioactive and does not pose any threat or pollution to the environment,” the company explains. “Therefore, unlike existing chemical batteries, nuclear batteries do not require expensive recycling processes.” "

Key word 'after decay period', which means after it's lost all or most of its radioactivity.. still a lot of time.
