The radiation they give off is blocked by a few
sheets of paper. They're alpha waves. Now,
fragments of the paint or the radium gas itself,
that's a different matter. Don't disassemble the
dials in your house, don't work on the gear in
your house and if it looks like the paint is
flaking, keep it in the garage. The radium gas,
degrades into various elements that are solid
isotopes, each step giving off radiation and
degrading into other isotopes based on half life.
So, you don't want to be breathing the radium
into your body. Stuck, behind a gauge face, it's
fine. Just don't mess with it.
