From the word radium, the substance from which it is derived. It is a radioactive, colorless, odorless, tasteless noble gas. Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soil. Radon can also be found in water. Radon escapes easily from the ground into the air, where it decays and produces further radioactive particles.
Possible symptoms include shortness of breath difficulty breathing , a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing. Elevated levels of radon gas have been found in homes in your state. Contact your state radon office for information about radon in your area.
A safe level of radon gas is no radon gas. Radon gas is a carcinogen which causes lung cancer. But it still may be a problem in your home. When you breathe air containing radon, you increase your risk of getting lung cancer. In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today. Your costs may vary depending on the size and design of your home and which radon reduction methods are needed.

Date published: May 11, Date published: March 6, Date published: June 12, These two studies go a step beyond earlier findings. They confirm the radon health risks predicted by occupational studies of underground miners who breathed radon for a period of years.
Early in the debate about radon-related risks, some researchers questioned whether occupational studies could be used to calculate risks from exposure to radon in the home environment. This research confirms that breathing low levels of radon can lead to lung cancer. This report by the National Academy of Sciences NAS is the most definitive accumulation of scientific data on indoor radon. The report confirms that radon is the second leading cause of lung cancer in the U. The study fully supports EPA estimates that radon causes about 15, lung cancer deaths per year.
The Agency's updated calculation of a best estimate of annual lung cancer deaths from radon is about 21, with an uncertainty range of 8, to 45, , which is consistent with the estimates of the BEIR VI Report. A single risk model also permitted the Agency to calculate a numerical estimate of the risk per unit exposure [lung cancer deaths per working level month WLM ] which will be used to update estimated lung cancer risks from radon in various publications, including A Citizen's Guide to Radon.
January 13, U. Surgeon General, Richard H. Carmona, issues a Health Advisory warning Americans about the health risk from exposure to radon in indoor air.
