- 50% Uranium sample (by mass)
- 2x2x2 inches
- Made In USA
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. It is one of the key components to nuclear energy.
This sample of Uranium is a beautiful green form called Autunite. It is 50% uranium by mass and is a naturally forming crystal of Uranium. It is not regulated by international shipping laws because it is a natural crystal specimen. It is slightly radioactive but the acrylic shields most of the Alpha and Beta particles. Autunite is becoming increasingly hard to collect. This sample will glow under a black light.
Tested on a giger counter and hit 2.48nm.
Great little gift! I love how it glows green under black light. However, mine came slightly shifted to one side (horizontally to the right), hence why I took 1 star off. Otherwise, it’s a great little specimen.
