Comment on bioluminescence

this reminded me of the clock girls story, “radium girls”, I think.
but since bioluminescence is powered differently, it’s a way better approach than artificial splashes of paint.

It’s fairly easy to find radium dials up to these days. You can spot them based on the yellowish and crumbling look of the paint or once luminous compounds. They may not be glowing any longer but they retain their radioactivity. By contrast, tye greenish white paint on dials is usually tritium.
