Testing is the only way to know if radon exists in a home since you cannot smell, taste or see radon. There are no immediate symptoms that will alert you to the presence of radon. It typically takes years of exposure before any problems surface.
The primary routes of potential human exposure to radon are inhalation and ingestion.
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.
