This Radon Awareness Month, the Public Health Directorate of the Laurentian Integrated Health and Social Services Center (CISSS des Laurentides) emphasizes the health risks linked to elevated radon levels in homes. Exposure to high levels of radon can significantly impact health.
Radon, a naturally occurring radioactive gas, is produced by uranium decay in the earth’s crust. Outdoors, it disperses harmlessly in the air, but when it seeps into buildings—mainly through foundations—it can accumulate, reaching concentrations that pose health risks.
With many people converting basements into home offices or children’s rooms, the potential for radon exposure is increasing. Radon is invisible, odorless, and undetectable by the senses, making it essential to monitor its concentration to keep levels within safe limits.
Long-term exposure to high radon levels increases the risk of lung cancer, making radon the second-leading cause of lung cancer after smoking and the primary cause among non-smokers. In Quebec, radon exposure is associated with 10 to 16% of lung cancer deaths, totaling over 1,000 fatalities annually.
Testing Radon Levels for Health Protection
The easiest way to determine radon concentration in a home is by using a radon test kit, known as a dosimeter. Homeowners can perform the test themselves or seek the services of a radon measurement professional. If the results reveal high radon levels, corrective measures can be taken.
