I've seen some very impressive uranium pieces in fluorescent displays, which were in glass display cases. Exactly! I don't know if mine is fluorescent though, need to test it. |

Seen any pretty uranium that doesn't require special lighting?

Used to be able to buy uranium specimens at Knotts Berry Farm in California, in the rock shop. A uranium hunter friend got all excited when he waved his magic wand across my specimen. Wanted to know where I found it. His gieger counter was buzzing like a whole den of rattlers.

The cases I have seen turned the diamond a beautiful dark, dark brown. Pretty neat looking, very different.

So part of the collection I acquired from my grandfather included several chunks of uranium ore. From what I know about uranium, its not really to radioactive, although I probably don't want to stick it under my pillow at night. Got it all wrapped in tinfoil now so the kids don't go licking it, but what can I do with it? What is the best way to display it? Does it make for some good cabs?  You can pack it around the wife's wedding ring and turn the diamonds a beautiful green. Green diamonds form from the natural radiation in the ground they are exposed to. As cool as this sounds, I don't think the wife would appreciate it to much. Does this only work on diamonds? |

If you want to display a piece, get one of those lead crystal domed lids to cover it with. I think they call them bell jars. Set the display piece on a small sheet of lead and cover it with the bell jar. The small amount of radiation you'll get while putting your display together will be less that the radiation I used to receive while TIG welding aluminum, using Thoriated Tungsten electrodes.
If you want to cause a stir around a work site where radiation monitoring is routinely done, visit your friendly weld shop and ask for a short stub of Thoriated Tungsten electrode. Hide it under your watch band and go through monitoring.

Who, Meeeeee ? Nah, not meeeeee !! LOL. Shoulda seen the excitement. I was running the sheet metal shop on a sub tender. They decided to check the radium dials on everyone's watches. Mine really set the detector off.

Ah Geoff, now ya went and did it. I just put a bid in on a nice specimen of Autunite. Florescent a beautiful yellow/green under short or long wave UV. Now I have to shop ebay for some thin sheet lead, so I can solder up a small storage box for it. Don't think mama will want me storing it in one of her lead crystal candy dishes.

Lol, just by a crappy lead crystal dish of your own on eBay! Autunite will be fine in a perky box.

That's what it gets shipped in, a perky box. But due to postal regs, they have to wrap it in lead foil to ship it.
Many years ago I was certified in Non destructive testing. D.P. - M.P. Ultrasonic and radiological. Played with my share of sources and lead pigs. LOL. Got tired of being responsible for the lives of entire nuke sub crews and let my certification drop.

Oh, Oh. Just googled autunite. It is shown only under special lighting; same at mindat.org.
What does it look like in daylight? Concerned because I have a chunk with the same form, but the plates are dark and the base is white. Out in the garden... size of a double burger.

By the way, the specimen I'm bidding on emits Alpha, Beta and Gama rays. It measured at 14.41 uSv/hr

I think I put off more after servicing a 10Ci neutron source...

No doubt. At my age, I wouldn't be afraid of licking this specimen. I've on several occasions crawled through a little hatch with a man standing watch over me with a loaded .45, and sat on top of a submarine nuclear reactor while taking measurements for additional shielding. I still don't glow in the dark. LOL

As cool as this sounds, I don't think the wife would appreciate it to much. Does this only work on diamonds? I have only heard of this being done on diamonds. The reason is that the color of diamonds is not just from impurities as with most stones. With diamonds vacancies within the structure also alters the colors we see in diamond. In other words diamond would normally be a series of carbon atoms C-C-C-C-C-C....... But the radiation can alter some of the carbon in to nitrogen (C-C-C-N-C-C-N-C-C-C-C......) or can simply create vacancies (C-C- -C-C-C- -C-C-C.....). |
