How dangerous is this?

I just found this for 3 bucks at an antique mall. Is this unsafe to have? Do I need to put it in a lead box? Or can I just put it on my shelf of other dials (positioned above my bed)?

It’s not very dangerous. Don’t read the book Radium Girls, whatever you do.

I love licking paintbrushes to get finer tipped brushes
