Radon is a radioactive gas that accumulates when radium in the soil decays. It may build up in basements or other enclosed areas. Radon is colorless, odorless and difficult to detect. However, the University of Minnesota estimates that more than half of the average human's radiation exposure comes from being in contact with radon.

Signs of Radon Exposure
Exposure to radon may increase the chances of contracting lung cancer. There are no physical signs of radon exposure, and no acute or chronic symptoms before contracting cancer, making the gas especially dangerous. Radon is invisible and can easily escape detection, but there are factors that may increase your risk for radon exposure.
Because there are no symptoms for exposure, it is especially important to test your home for radon. Otherwise, you may not know that you're being exposed. Radon test kits can be purchased at home improvement stores, and only take a few minutes to set up and use.
Well Water
If you live in a radon-contaminated area and have a home well for your water supply, it's important to know whether your water is contaminated. If your home tests positive for radon, be sure to have your water evaluated as well. Otherwise, radon could be leaching into your drinking water.
Spending Time in Enclosed Underground Areas
Radon gas accumulates in enclosed areas underground. If you are a miner, plumber, or other professional whose job frequently takes you underground for long periods of time, it's important that you are aware of the risks. Ask your supervisor about the steps that your company is taking to minimize your exposure to radon gas.
Geography
If you live in the Midwestern U.S. there is a higher geological concentration of radium in the ground. For this reason, it is incorrectly believed that residents of these states are the only ones who need to worry about radon exposure. The University of Minnesota states that nearly every state in the U.S. has homes with radon levels that are above acceptable limits. No matter where you live, it is important to install a radon detector in your home.
