What are the health affect associated with radon?

There are no known immediate symptoms from radon, whereas health problems are often seen after long exposures to elevated levels of radon indoors. In the outdoor air it is harmlessly dispersed. When radon in the air is inhaled into the lungs the process of radioactive decay begins. This leads to the DNA of our sensitive lung tissue being damaged both physically and chemically. 


Scientists and researchers categorize radon as a Group A carcinogen meaning that there is no known acceptable level of exposure and that it has been demonstrated to cause cancer. Other Group A carcinogens include tobacco smoke and asbestos. 


Radon is the number one cause of lung cancer in non-smokers and the second leading cause of lung cancer (after tobacco) in smokers. Thankfully, this risk should be entirely preventable through awareness and testing.
