Why Buy Uranium
Not many people can say that they own a piece of actual uranium. This sample of Uranium is a beautiful green crystal called Autunite. It is definitely a great conversation piece or a good way to keep annoying coworkers from coming to your desk. (*Requires a UV light to illuminate/fluoresce)
It is 50% uranium by mass and is a naturally forming crystal of Uranium. Natural uranium contains about 0.7% uranium-235 which is the fissionable isotope used in nuclear reactors. This sample has about 2.5 grams of autunite which translates to about 8.75mg of the same isotope that nuclear bombs are made out of! The remaining 99.3% is U-238, also known as depleted uranium.
Uranium is a chemical element with the symbol U and atomic number 92. In it's pure form it is a silvery-grey metal but this sample is obviously not the metal form. Uranium is part of the actinide series of the periodic table.
Most people think of modern technology when they hear the word uranium since it is the key element in nuclear energy and nuclear weapons. However, Uranium was actually used as far back as the middle ages as a color additive to glass.
It is not regulated by law because it is a natural crystal specimen. It is license exempt and considered a Radioactive Ore Sample or Naturally Occurring Radioactive Materials (NORM). That being said, Autunite is becoming increasingly hard to find and collect.
The cube is slightly radioactive but the acrylic shields most of the Alpha and Beta particles. Background radiation we are exposed to this every day is about 30CPM. These samples measure anywhere from 60 to 120 CPM. So about 2 to 4 times the background radiation. In comparison you would receive more radiation flying on an airplane. X-rays at the doctors would be thousands of times this does. Also a side note the FDA allows for a person to consume about 20mg of uranium in their drinking water every year. The bottom line is that this cube is very safe unless you were somehow able to break it open and make pistachio pudding with it.
Fantastic quality, and fast delivery. Highly recommend Engineered Labs products 🙂
Uranium Element Cube (Autunite) ***BACK-ORDERED***
A sizeable sample given it's form. I am thoroughly pleased to add this sample of Autunite to my uranium glass collection. It literally glows as bright as some of my uranium glass plates under UV.
This piece is just amazing. Also purchase a UV light - it is superb.

Great product, very well made, good idea for gift.
