Plutonium's atomic number is 94 and its symbol is Pu. Named after dwarf planet Pluto, itself named after the classical god of the underworld Pluto. Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized, and can display up to five different colors depending on its oxidation state.
Plutonium oxide forms on the surface of plutonium exposed to air. The oxide is pyrophoric, so pieces of plutonium might glow like embers as the outer coating burns. Plutonium is one of a handful of radioactive elements that "glows in the dark," although the glow is from heat.
Plutonium makes up the core of nuclear weapons and has also been used in such things as batteries for spacecraft and radioactive sources for smoke detectors.
Because plutonium is so versatile and useful from nuclear weapons to home fire safety you may be thinking to yourself "Gee, why doesn't everyone own plutonium?". Besides the poor reputation that this pesky element has gained over the years, it is also extremely hard to get a hold of. The plutonium in this element cube is from soviet era smoke detectors that were only produced in limited numbers. Now, most of these vintage smoke detectors are quietly bought by collectors never to be seen on display by the public again.
Although the plutonium in this sample is indeed present, it is a very small amount. Because of this small amount, we have confirmed that there is no detectible radiation from a cm away from the cube. It is therefore perfectly safe to proudly display anywhere from a bedroom to a museum.
Shipping laws restrict us to only shipping these models within the United States. Due to the difficulty of obtaining these plutonium samples, we are unsure if we will be able to get more. So far we have been able to get 9 total. Once they are sold it may be years before we can produce more samples if we will ever be able to get more.
