URANIUM MADE FIESTA WARE COLORFUL … AND RADIOACTIVE.īefore we recognized uranium's potential for energy-and bombs-most of its uses revolved around color. But here's the good news: After short-term, low-level exposures, kidneys can repair themselves. Kidneys take the burden of removing it from the bloodstream, and at high enough levels, that process can damage cells, according to the Argonne National Laboratory. Traces of uranium appear in rock, soil, and water, and can be ingested in root vegetables and seafood. IF YOU INGEST IT, THANK YOUR KIDNEYS FOR KEEPING YOU ALIVE. In a frenzy to achieve a state of rest, it slings off a missile of two protons and two neutrons at a velocity fast enough to whip around the circumference of the earth in roughly two seconds." 4. As Tom Zoellner writes in Uranium: War, Energy, and the Rock That Shaped the World, "A uranium atom is so overloaded that it has begun to cast off pieces of itself, as a deluded man might tear off his clothes. Before Ernest Rutherford and Frederick Soddy discovered this trait around 1901, the notion of transforming one element into another was thought to be solely the territory of alchemists. Uranium decays into other elements, shedding protons to become protactinium, radium, radon, polonium, and on for a total of 14 transitions, all of them radioactive, until it finds a resting point as lead. ITS TRANSFORMATIONS PROVED THE ALCHEMISTS RIGHT … A LITTLE. He left uranyl potassium sulfate, a type of salt, on a photographic plate in a drawer, and found the uranium had fogged the glass like exposure to sunlight would have. He named it after the recently discovered planet Uranus.įrench physicist Henri Becquerel discovered uranium's radioactive properties-and radioactivity itself-in 1896. It generally appeared where the silver vein ran out, earning it the nickname pechblende, meaning "bad luck rock." In 1789, Martin Klaproth, a German chemist analyzing mineral samples from the mines, heated it and isolated a "strange kind of half-metal"-uranium dioxide. Uranium was first found in silver mines in the 1500s in what's now the Czech Republic. Were it employed that way now, sailing into port could set off defense systems. That weight once compelled shipbuilders to use spent uranium as ballast in ship keels. With a nucleus packed with 92 protons, uranium is the heaviest of the elements. IT'S THE HEAVIEST NATURALLY OCCURRING ELEMENT IN THE UNIVERSE. In the first half of the 20th century, scientists began investigating uranium's innate potential as an energy source, and it has earned its place among the substances that define the "Atomic Age," the era in which we still live. After formal discovery of the element in the late 18th century, it found a useful niche coloring glass and dinner plates. For centuries, heaps of it languished in waste rock piles near European mines. How well do you know the periodic table? Our series The Elements explores the fundamental building blocks of the observable universe-and their relevance to your life-one by one.
