I inherited my grandfather’s WWII compass, and had it sitting around for a long time on a shelf. I recently got a Geiger counter, and find that it’s radioactive. Around 10 microsieverts/hr. Apparently they used radium paint to make them glow in the dark. I can’t just throw it away, but I don’t want it potentially causing a danger to others in the room. Is there some sort of lead lined box I can put it in, or some kind of prevention I can do? Is there anyone experienced with this sort of thing that can offer some advice?

    That’s handy and I’m bookmarking it for quick reference. I have one for the Geiger counter, but it’s just numbers and doesn’t have examples.

    Thanks!
