Radioactive facts about uranium
Uranium was discovered by German chemist Martin Heinrich Klaproth in 1789
Uranium's color -
Pure uranium is silver, but it oxidizes quickly when exposed to air
Where did it come from? -
It’s believed that uranium was formed in a supernova about 6.6 billion years ago and made its way to Earth.
Rate of decay -
The exception is Uranium-214, which is made artificially and has a half-life of half a millisecond!
When uranium is used to color glass, it glows in the dark under black light.
Nuclear fission -
This by no means makes it safer when it comes to explosive potential.
Nuclear bomb -
Only 1.38% of the uranium in the bomb underwent fission. In total, the "Little Boy" bomb contained 140 pounds (64 kg) of uranium.
Enriching uranium fission -
Nuclear power plants use enriched uranium to generate energy.
Depleted uranium -
The leftover product is depleted uranium, which is then used in things such as bullets or tank armor.
Solid uranium oxide -
Yellowcake is the name given to solid uranium oxide.
Uranium is mined in 20 countries around the world. The vast majority of it comes from Kazakhstan, Namibia, Canada.
We’re all exposed to uranium -
We are all naturally exposed to very small amounts of uranium.
Radioisotopes are also used in the preservation of food, from killing pests to controlling the ripening of fruit and vegetables.
Radioisotopes are widely used for diagnosis and research.
