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?

It’s a compass though :-)
You don’t wear your compass? How do you know where to go?
I walk at a constant speed and use my wristwatch to measure time, so I can calculate distance :-)
