Huron Perth Public Health is encouraging residents to test their homes for radon as part of Radon Action Month.
Radon is an odourless, colourless and tasteless gas produced by decay of naturally occurring uranium in soil and rocks.
Radon gas can travel into homes unnoticed through cracks in the foundation of floors, gaps, around pipes or cables with long term exposure being the second leading cause of lung cancer.
Public health recommends residents test their homes for radon using a long term test.
Dana Merrifield, Public Health Inspector says once you know the levels of radon in your home, you can take the steps to lessen the risks and protect your health.
