Radon - A Silent Danger in your Home?

TORONTO — Nov 13, 2018: Many homeowners understand that a build-up of carbon monoxide can be dangerous but few know about another invisible gas that may also pose a risk. As part of National Radon Action Month, Tarion Warranty Corporation is helping homeowners understand the facts about radon and how to protect their homes.
Here are five basic facts all homeowners should know about radon:

  1. Radon is a radioactive gas that occurs naturally in the soil and is found in almost all homes in Canada. Concentration levels can vary widely from area to area and even between homes in the same neighbourhood.
  2. With proper ventilation, radon will dissipate causing no problems at all. Unfortunately, enclosed spaces without good airflow – such as basements, crawlspaces – can develop dangerously high radon levels when the gas becomes trapped.
  3. Radon is measured in units called ‘becquerels’ and Health Canada has set 200 becquerels per cubic metre as the safe limit for radon in a home.
  4. An estimated 7% of homes in Ontario have radon levels higher than Health Canada’s safety standard. 
  5. Radon is not the result of a defect in the way a home is constructed. There is no way to determine if radon is going to be a problem before a home is built.

“The only way to determine if a home has excessive radon levels is to test,” says Siloni Waraich, Vice President, Stakeholder Engagement. “You can either use a do-it-yourself radon test kit or hire a radon measurement and mitigation professional, both should be certified through the Canadian National Radon Proficiency Program.”

New homes in Ontario are covered for excessive radon for seven years under the new home warranty.
