Uranium
Uranium is a naturally occurring radioactive
metal. It is found in small amounts in rocks, soil, water, and
air and contributes to the weak background radiation that is found
everywhere. Uranium ore is mined, milled, and then chemically concentrated
by a process called "enrichment." Uranium is used in
nuclear power plants and nuclear weapons, and small amounts can
be found in ceramic glazes, light bulbs, photographic chemicals,
and other household products. As a result, we are exposed to small
amounts of uranium daily. People can come into contact with larger
amounts of uranium by working at nuclear power plants, weapons
production facilities, or uranium mines and mills.
Exposure to uranium
generally occurs through inhalation and/or ingestion. Inhalation
of airborne uranium dust is the most common means of workplace
exposure. Once inhaled, uranium dust can leave the body through
exhalation or urination. Workers may also be exposed to uranium
at work through ingestion of uranium-contaminated food and water.
If uranium is ingested, most of it will leave your body within
a few days through your feces. However, at times, uranium can remain
in the lungs, or it can enter the bloodstream, kidneys, and/or
bones, possibly causing damage to these organ systems.
Due to the
fact that uranium is a heavy metal, and is radioactive, exposures
can lead to short-term or long-term side effects. If you have had
significant exposure to uranium, you may be at risk for kidney
disease, and/or bone or lung cancer. Urine and blood tests can
help determine if you have been exposed to uranium. Factors that
determine whether you have been harmed by your exposure include;
how much uranium you came into contact with, and the duration of
the contact. An examination by a physician trained to recognize
signs of exposure to uranium, can help identify some of the health
effects of such an exposure. The physician can then advise you
on how to reduce your health risks and refer you for additional
testing if necessary. |
