If it’s a small battery intended to be used a long time, pretty much a guarantee these are going to end up in the general landfill waste stream.
I wonder how much contamination one of these will cause if it goes through a waste incinerator. If they have 50 Curies of activity, that’s more than a million times what’s in a smoke detector.
They decay into copper, which can be easily recycled.
Yeah, but it’s radioactive nickel-63 for many decades until it all decays.
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.
