It became popular in the U.S. and uranium was widely used to color glassware until 1943, when the government started regulating its use so that they could save uranium to build atom bombs.
Some collectors attempt to collect very high purity samples of each element. Others prefer to find the element in everyday use. Some are averse to collecting the element as a compound or alloy, while others find this acceptable. Collectors may isolate elements in their own homes.

The highest grade uranium deposits are found in the Athabasca Basin in Canada, including the two largest high grade uranium deposits in the world, Cigar Lake with 217 million pounds (99,000 t) U 3 O 8 at an average grade of 18% and McArthur River with 324 million pounds (147,000 t) U 3 O 8 at an average grade of 17%. These deposits occur below ...
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. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
Uranium in the environment is a global health concern, and comes from both natural and man-made sources. Beyond naturally occurring uranium, mining, phosphates in agriculture, weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment.
Uranium has been hot this year, industry experts say. The trouble is there may not be enough to go around. The squeeze on the metal, found in rocks and seawater, intensified recently after 22 ...
Natural uranium (NU or U nat [1]) is uranium with the same isotopic ratio as found in nature. It contains 0.711% uranium-235 , 99.284% uranium-238 , and a trace of uranium-234 by weight (0.0055%). Approximately 2.2% of its radioactivity comes from uranium-235, 48.6% from uranium-238, and 49.2% from uranium-234.
