Radon Health Effects

  • Radon gas decays into radioactive particles that can get trapped into your lungs when you breathe, according to the Virginia Department of Health.
  • As they break down further, the particles release small bursts of energy which can damage lung tissue and lead to lung cancer over the course of your lifetime. Not everyone exposed to elevated levels of radon will develop lung cancer.
  • Exposure to indoor radon, a colorless, odorless radioactive gas, is thought to be the second leading cause of lung cancer
  • It’s the leading cause of lung cancer among people who have never smoked
  • Exposure to radon may contribute to 21,000 cases of lung cancer each year in the United States, including almost 700 cases per year in Virginia.

ROANOKE, Va.Your chances of getting lung cancer from radon depend mostly on:

  • How much radon is in your home
  • The amount of time you spend in your home
  • Whether you are a smoker or have ever smoked
