Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated. Radon isotopes are the immediate decay products of radium isotopes. The instability of 222 ...
Radon is part of the environment and generally isn't harmful. But long-term exposure to high levels of radon can put you at risk of developing lung cancer, especially if you smoke.
Learn about radon, a naturally occurring radioactive gas that can cause lung cancer. Find out how to test your home, reduce your risk and access resources from the EPA and other sources.
Radon and Your Health Key points Radon is an odorless and invisible radioactive gas naturally released from rocks, soil, and water. Radon can get trapped inside homes and buildings, and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.
Learn about radon, a radioactive gas that can seep into buildings and increase your risk of lung cancer. Find out how to test, prevent and treat radon exposure in your home, school or workplace.
Radon and other alpha emitters can be detected through laboratory tests. These test kits are available at the Maine Health and Environmental Testing Laboratory or other private laboratories. A list of radon testing laboratories can be obtained from the Radiation Control Program at the DHS Division of Health Engineering.
Did You Know? Radon is an odorless, tasteless, and invisible radioactive gas that can seep into homes, increasing the risk of lung cancer, particularly among non-smokers, and is responsible for approximately 21,000 lung cancer deaths annually in the U.S. Testing for radon in homes is essential due to its invisible nature.
Radon is a radioactive gas that can cause lung cancer if you breathe it in over a long time. Learn about the symptoms, risks, sources, and prevention of radon exposure.
Radon is an odorless, invisible, radioactive gas that can enter your home from the ground through cracks in the foundation. A known human carcinogen, radon is the second leading cause of lung cancer.
