Well outside of outdated and shunned photographic processes or making your own thoriated lantern mantles...

I kept seeing that, but having no idea what a lantern mantle was I figured I would ask.

The problem here is that it is a powder, which makes it a high contamination risk, especially if handled by a novice, or worse, someone who doesn't know what they're doing.

That's me! I want some. Do I snort it?

Lol.

A lantern mantle is a cloth bag set over the burner in a gas/oil lantern. The flame burns up the cloth which is impregnated in a chemical. The chemical gets hot and glows incandescently like a light bulb. All that is left of the lantern after ignition is a weave of oxides, if you touch it or blow on it, it turns to a dust cloud. So instead of a dim light from a small flame, you get a bright white net of oxides glowing from the heat of the flame. In the case of thoriated mantles the thorium nitrate is the chemical which upon ignition converts to thorium oxide, which glows from the heat. The problem is thorium is radioactive. It primarily an alpha and gamma emitter, and since it is a dust it poses an inhalation hazard. You can take a very large dose of external radiation with no real health risk, but even a super tiny quantity of radioactive material can cause cancer if it gets IN your body, like if you breathe in Th mantle dust.

People used to brush their teeth with radium enriched toothpaste for a glowing smile.

BTW, if the gov't ever finds out you had a spill of radioactive material they will force a full size cleanup on you and hand YOU the bill. If you're going to collect rads, make sure they are sealed exceptionally well or are not able to cause contamination (don't collect Ore indoors, liquids/gasses/powders/crumbles should be in ampoules.)

Re: Stuff for sale

Could that thorium nitrate be used as a cloud chamber source inside your container(to reduce risk of exposure)?
Also, how much is that amount worth in cash? Assuming you don't get a trade lined up, I might take it off your hands as a sale...

Bump...

Price Drop!

I'm in for a 9kV transformer if you can ship to Brazil (zip code 30421-131), as long as the shipping doesn't cost a fortune
