Radon is a cancer causing radioactive gas. In fact, radon is listed as a Class A
carcinogen, meaning it is known to cause cancer. EPA estimates that about
21,000 annual lung cancer deaths are radon related, and the Surgeon
General warns that radon is the second leading cause of lung cancer in the
United States. The State of California Department of Public Health estimates
that 1500 lung cancer deaths in the state each year are attributable to radon.
Radon gas decays into radioactive particles that can get trapped in your lungs
when you breathe. As they break down further, these particles release small
bursts of energy that can damage lung tissue and lead to lung cancer. Not
everyone exposed to elevated levels of radon will develop lung cancer, but
the chances of getting lung cancer depend mostly on how much radon is in
your home, how much time you spend in your home, and whether you are a
smoker or have ever smoked.
