Does anyone (in the UK) have any interest in 2 Amaricium 242 smoke alarms?

I swapped them out as they are well out of date and while I’m not that in to Chemistry, I acknowledge the interest in elements and what you can learn.

I don’t want any money for them, I’m just against scrapping (through the correct channels) if someone could benefit.

Mods, If this isn’t allowed then delete but I did read the rules and couldn’t see a no for this.

For obvious shipping issues, I won’t mail them outside of the UK.
