Oh well, you know, back the in these days people also wore wristwatches that glew glowed in the dark. because they were made of Radium-226, and also used x-ray machines as a party gimmick. And when you felt a little sick you went to your local drug store and got yourself a bit of Radithor, a wonder medicine sold in a flask containing water enhanced with radioactive radium isotopes to cure your sickness.

You could have lots of fun as an adult too, back in the days. Maybe not the healthiest life decisions possibly, though, in rerospective.

But luckily there's another medicine product from Bayer called Heroin to compensate, or Pervitin to the rescue. Latter is nowadays called Methamphetamine.

I think the radium thing lasted a lot longer than one would expect. I had one of these in the UK in the late 70's (I think I was 7 or 8 at the time).

Yep, radioactive fluorescent paint was used for a long time beyond that. In clocks and wristwatches you'd find Radium based paints until the 1960s, Tritium based paints even even until the 90s in some places.

Modern clocks may still use gaseous tritium. It's said the latter is safe.

What do they use now for luminous watch hands and numbers? Also gaseous tritium? I have one from about 10-15 years ago and it still works.

The most popular watch lume brands like Super-Luminova and Lumibrite are made from strontium aluminate. It got popular in the 90s.

My watch is Casio. I always assumed that the glass was sufficient protection from whatever was used.

The modern ones are Phosphorescent. They have to be "charged" with light. The old radioactive stuff would still be glowing just the same after spending a year in a dark closet. But once it stopped glowing it was done, no charging it back up.

Glass vials containing a phosphor and tritium gas. Used by a number of watch-makers (Ball Watches being one of the more creative ones when it comes to colors). Same thing for night-sights on firearms. If the vials are broken, the gas dissipates quickly so it’s a better alternative than radium based glow-in-the-dark stuff.
