The leachate is a mixture of crushed ore, water, acid, manganese and iron. Its uranium content is as in the mined ore (about 300 ppm), but diluted with the liquids, so radioactivity is significantly less than that of mined ore. The area where the tank failed has since been demarcated and made safe to prevent unauthorised entry.

It was lined with carnotite (Hydrated Potassium Uranyl Vanadate), a uranium ore which, like any uranium or thorium ore, emits radon gas at a steady rate as a decay product of the uranium. I've listed the item under radium as well as uranium, because although it's lined with uranium ore, the Revigator is glazed with the words "Radium Ore Revigator".

After extraction, the uranium ore is transported to a processing plant where it is milled. This process involves crushing the ore, chemically extracting the uranium, and concentrating it into yellowcake. Contact: Robert Gregory (307) 766-2286 Ext. 237.
Uranium ore is a finite resource on the Earth, and carries considerable danger. Although the refined product can create abundant energy, its radioactivity can potentially be a source of contamination and is dangerous to humans. Additionally, the mining process can be severely destructive to local ecosystems; in 2008, the United States government enacted a protective measure for the state of ...
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 is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
