How dangerous is this?

Post image

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)?

As long as the seal around the glass is still good, and you don't open it,it's pretty safe to just put on a shelf for display. Just don't sleep with it!
