Uranium is a naturally occurring element. It is found in low levels in nearly all rock, soil and water. Higher concentrations of uranium sometimes occur in substances such as phosphate rock deposits as well as minerals like granite found in uranium-rich ores.
Uranium metal is very dense and heavy and given to many military uses such as shielding and components of bullets and missiles.
Weathering canto trace amounts of uranium reaching the water supply, and very low amounts, when not ingested over a long period of time is not a threat. However in higher concentration, or continued exposure over time, uranium has been linked to kidney damage, as well as liver damage and increased risk of cancer.« Back to Glossary Index
