SIMCOE MUSKOKA – Radon is an invisible, colourless, and tasteless radioactive gas that naturally occurs when uranium in the soil and rock decays and can enter your home unnoticed, posing a risk to your health. During Radon Action Month, the Simcoe Muskoka District Health Unit is encouraging residents to test their homes for radon.

Radon is the leading cause of lung cancer after smoking, causing nearly 16 percent of lung cancer deaths annually which is equal to about 850 lung cancer deaths each year in Ontario. The gas is naturally found in the environment and can enter your home through cracks in foundation walls, gaps around pipes, drains, or sump pumps — often undetected.

Long-term exposure to radon can increase the risk of lung cancer depending on the amount of radon present, the length of time you are exposed, and whether you smoke. Smoking, combined with radon exposure, significantly increases your risk of developing lung cancer.

Checking your home for radon is simple and can be done with a do-it-yourself kit. You can find information about where to purchase a Health Canada approved kit and how to use it at Take Action on Radon or by contacting a certified radon professional.

The Canadian guideline for radon is 200 becquerels per cubic meter. When levels exceed this guideline, action is recommended. A long-term test is recommended.

If you detect higher levels of radon in your home, contact a certified radon professional to help you reduce the radon levels in your home. The discovery of radon is a warrantable defect under the Ontario New Home Warranty and Protection Plan for new homes that are seven years old or less. Homes older than seven years are eligible for home radon mitigation support through the Canadian Lung Association.
