That is very interesting to see. I have no idea what would be the tell tale signs its hot. Could you please share what points to this?

fossils with these colors, from what I have read, are generally found around areas that contain uranium.

Gorgeous piece of wood, bhiatt. fossils with these colors, from what I have read, are generally found around areas that contain uranium. Very interesting bit of information and didn't know this. Thank you for sharing. |

Great specimen. The yellow color can be an indicator of radioactivity, but not always. Some of the Arizona wood with yellow coloring is mildly radioactive.
Got any dentist friends ? One of those little ex-ray plates they stick in your mouth could be exposed to your specimen by just laying the specimen on top of it for a while.
When developed, there would be an interesting pattern on the plate.

Those are some pretty colors.
Yes, stuff from Utah can contain uranium. The operative words, though, are LOW levels. A Geiger counter would quantify it.

The level of radiation probably isn't hot enough to harm you. But just to be on the safe side you might want to display it in a tight fitting acrylic box. The little gem boxes are all of the shielding most "hot" specimens need. I have several radioactive mineral specimens which I store inside the house in a small lead lined box.

Interesting bit of information in this thread! Nice to know to as we have a few areas here that have uranium mines close by.

I thought the green color was caused by chromium. I guess maybe in pet wood from other than Utah? I have some green wood from an estate sale, I believe it is from Hampton Butte (Oregon).
Nice where ever it is from. Probably only minute quantity, like @shotgunner says. Should be safe.

Nice where ever it is from. Probably only minute quantity, like @shotgunner says. Should be safe. That particular shade of green looks like nickel. But like bloodstone could be iron too. The yellow may be the source of uranium or it could also be iron and no color is imparted by the uranium. Iron is quite versatile in the colors is gives. Purple, yellow, green, red, orange, black. Almost any color but blue! |

On your next airplane flight, stick that rock in your pocket. Security will let you know if it's radioactive. This happened to a friend who bought some material at a show in Arizona. They pulled her aside to find out what she had in her bags.
