3 inch Uranium Cube (Free Geiger Counter, UV light)

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)

Technical Info  

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 15 grams of autunite which translates to about 52.5mg 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 its 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. 

Regulations

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) according to 10CFR in federal code. That being said, Autunite is becoming increasingly hard to find and collect.

Please note that this item might be classified as hazardous material in certain countries. We suggest checking local guidelines to ensure compliance before placing your order.
