Your home’s indoor air quality may be one of the most significant indicators of your long-term health and wellness, despite being one of the most invisible elements of the home environment. At SafeAir, we help families assess the health of their indoor environment by addressing hidden or little-known air quality problems such as radon gas. Radon is a naturally occurring radioactive particle that poses a well-documented risk to human health. Radon testing is the only safe and reliable way to know if your home is affected, and what mitigation strategies might help reduce your exposure. Here’s what air quality testing in Toronto can reveal about your risk.
Understanding Radon and Its Risks
Radon gas is created by uranium deposits in the Earth’s surface. In normal circumstances, radon gas off-gasses from the surface and harmlessly dissipates in the atmosphere. It has no smell, is invisible, and leaves no residue. Buildings, however, can accidentally trap and collect radon through cracks and gaps in the building envelope and foundation, leading to a buildup that creates toxic, long-term effects.
How High Radon Levels Affect Your Family’s Health
Radon gas is radioactive, and, like all radioactive particles, has a half-life, after which it decomposes and “dies.” The concern with living in an environment affected by high levels of radon gas is when this process happens inside the human body. Radon is very easy to breathe in, and decades of research have found that when radon combusts in the lungs and respiratory tract, it causes dangerous cellular changes and damage. After tobacco smoke, radon gas is the leading cause of lung cancer in Canada, making it a serious air quality pollutant that could have a profound long-term impact on your family’s health.
Testing for Radon at Home
The only way to know if your home is affected by radon is to have it tested. At SafeAir, we test following the latest industry guidelines and practices to achieve safe and reliable results. Radon levels can vary throughout the year and may fluctuate with the weather or change after renovations, making accurate DIY testing a challenge.
At SafeAir, we prefer a long-term test to help even out inconsistencies and achieve an accurate test result. Our process is straightforward: we come to your home for a brief installation visit, during which we install the small, fire alarm-sized testing device. Three to six months later, we return and remove the device, sending it for testing at an accredited laboratory. When we receive the results, we create a report that helps you understand what we’ve found and any recommendations we have to reduce your risk. It’s a simple, trustworthy, and easy process.
Mitigation Strategies to Reduce Radon Levels
Health Canada’s guideline states that homes with 200 becquerels per cubic metre (Bq/m³) or more of radon gas require action to reduce your risk. There are many things you can do to prevent radon from entering the home or to vent collected radon out. The strategy you choose depends on your test results and the unique environment of your home. SafeAir can help provide guidance and interpret your results so that you can make a confident, informed choice.
