also tritium keychains, thorium gas lanterns, uranium-glazed fiestaware, uranium glass, uranium-glazed tiles, antistatic phonograph record cleaning brushes, thoriated camera lenses, thorium-oxide negative-ion generator bracelets, and radium-dial watches. some of these are dangerously radioactive and/or consumable, most are not
I've heard of some of those and I'm not aware that any of these are actively marketed in any relevant quantity anymore.
tritium keychains, americium smoke detectors, and antistatic phonograph record cleaning brushes are. you might even be able to find thoria gas lantern mantles
Although not marketed for the public at large, thoriated TIG welding rods are still a thing, and widely available too. They are consumable, and they need to be ground down to profile for use.
None of these are sold anymore in the country where I live. They are all optical nowadays.
Here in the US we use both (three types really) for different scenarios; they both have benefits in terms of “quickness” to detect smoke, fire, or heat.
