3inch cube vs 2inch cube  

With such a great response to our 2inch uranium autunite cube we wanted to try something a little more impressive.  Volume increases exponentially so although this cube is only 1 inch larger it is over 3 times the weight. The sample of uranium is also about 6 times the size of the those included in the 2 inch cubes. It weighs in at over a pound (530g) giving the cube some impressive heft when you pick it up. 

 

Free Geiger Counter 

This cube also comes with a free Geiger Counter (not made in USA like the cube).  The Geiger counter will detect Beta and Gamma radiation. If you are interested in radiation you can take this Geiger counter to an antique shop where you are almost guaranteed to find something radioactive.  In the 1950s people were fascinated with radiation and put radioactive materials in everything from watches to salt shakers. 

 

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 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. 

 

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. 

 

Safety 

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 0.15 microsieverts per hour. These samples measure anywhere from 2.5 to 3.5 microsieverts. So about 20 times the background radiation. In comparison you would receive more radiation flying on an airplane. CT scans at the doctors would be thousands of times this does. 

According to OSHA a safe level of radiation in any given year is 50,000 microsieverts. So feel free to strap it to a chain and where it like a status necklace because even if you wore it 24/7 every day of the year you would still only receive 50% of the safe  level of radiation that the government permits. 

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.
