    The Register's radioactive key rings

    So, I bought a set of four tritium keyrings from The Reg when I was living in the UK in the early 2000's. They were advertised as having a half-life of 10 years, which seems pretty accurate. I still have, and use, them all today (moved back to Aus in 2004). They're still glowing, faintly.

    Anyone else still have their tritium keyrings from The Reg?

      Hey I do - back when I bought one as a reader. It's attached to my keys and still glowing enough that I can see it in my bag or hanging on the wall in the dark, which is handy.

      When I bought one I thought it was just glow-in-the-dark watch paint and the radioactive stuff was a tongue-in-cheek Reg gimmick. Turns out it's true. We're carrying a little bit of tritium, a nuclear weapon ingredient.
