What is Radon?

Radon is a radioactive gas that is found in soil and rock in all parts of the United States. It is formed by the decay of uranium, which is a natural process. Radon gas is invisible, and it has no odor or taste.

What Types of Buildings Contain Radon?

  • Radon may be found in all types of homes and buildings in the United States. If there is radon gas in the ground, it can seep into a building.
  • Radon typically moves up from the ground into a home through drains, cracks or other holes in the foundation. Radon then can be trapped inside the home.

How Does Radon Affect Health?

  • Studies show that radon is the second leading cause of lung cancer, behind cigarette smoking.
  • The higher the radon level indoors, the greater the amount you breathe. Radon gas decays into radioactive particles that can get trapped in your lungs when you breathe. As they break down, these particles release small bursts of energy. This can damage lung tissue.
  • Inhaling indoor air containing radon over a period of many years can increase your risk of getting lung cancer. Your chance of getting lung cancer from radon depends on how much radon is in your home and how much time you spend in your home. If you are a smoker or a former smoker, the risk of getting lung cancer from radon is even greater. Does Your Home Have High Radon Levels? You cannot see, smell or taste radon. Therefore, testing is the only way to determine the radon level in your home.
