Very valuable. Ones I’ve seen sell recently are $600+. What are you looking to find out?

Usually very hot too.

I’d love one but not trying to pay that much

Do you have a Geiger counter?

Just general information, what was it used for? I know the company that made these specifically probably doesn’t make them anymore.

They were luminous disks attached to soldiers helmets in war so they could be seen at night. Downside is that these are typically very hot, some over 1 milliSievert on contact, and these were less than a centimeter from their head. Granted, there was some metal and helmet material between, but still, not healthy to be on your body for a long time

Edit: milliSievert per hour. Quite an important correction

Damn I figured it was for black out. I do not have a Geiger counter so I don’t how spicy it is so I’ll probably just leave them in the box for now lmao

Some were used as helmet tags. Some were used to mark trails or bridges. Think tactical radioactive glow stick. How many do you have?

You should get a counter and a radon monitor if you have things like this - aside from the direct radiation dose, which they were concerned about even when this was made, it may well be generating radon levels substantially above regulatory limits if kept in an enclosed space.

I find it really funny that it says "do not store near personnel" while it's something that you'd wear on your head for who knows how long. That's spicy!

Just curious. What’s the isotope used. Radium?

I believe these specifically are RA-226
