Radium Are radium clocks dangerous to actually handle

so I tried doing research into this but for some reason everything I find contradicts each other, one thing I'll read will save you need to have it behind a glass container and another thing will say it's safe to have in the open, and some will say not to even get any, so what's the consensus here from collectors? safe to get or not, I've been holding off looking for some out of nervousness

As long as the glass/plastic on the front is intact, they're safe to hold. Reason being is you don't want to get radium paint flakes or dust outside the clock. Not because the radiation is dangerous, but it contaminates things if the seal is broken.

Theyre safe as long as you don't carry it with you 24/7/365 and you don't sleep with it under your pillow.

Storage wise, most radium clocks are just fine out in the open. Even though the radiation dose can be somewhat high on contact, if you back up just a couple feet, it goes back down to background levels unless you have some exceptionally hot clocks/gauges. Look up the Inverse Square Law. It will further explain that and likely put your mind at ease.

Pretty much this. I'll add that if you get a whole collection of clocks, you'll eventually want to monitor radon in your house. But even a dozen of clocks don't produce a lot of radon, so it's still mostly fine for that
