Why Edmonton Homes Face Higher Radon Risks and What You Should Do

Radon is a naturally occurring radioactive gas that is colourless, odourless, and tasteless, making it undetectable without specialized testing equipment. It forms from the natural decay of uranium in soil and rock and can seep into homes through cracks in foundations, gaps around pipes, and other openings.​

In Edmonton, the risk of elevated indoor radon levels is significant due to the region's geology and climate. Health Canada reports that approximately 18% of Canadian homes have radon levels at or above the recommended guideline of 200 becquerels per cubic metre (Bq/m³), with certain areas in Alberta, including Edmonton, showing even higher percentages.

Long-term exposure to high radon levels increases the risk of lung cancer, particularly in smokers, but also poses a significant risk to non-smokers. In fact, radon is the second leading cause of lung cancer in Canada, following smoking .​

Given these risks, it's crucial for Edmonton homeowners to conduct professional radon testing in their homes. Testing is the only way to determine radon levels and assess the need for mitigation measures to ensure a safe indoor environment.

What Is Radon and How Does It Affect Your Health?

Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It can infiltrate homes through cracks in foundations, gaps around pipes, sump pits, and other openings. While low levels of radon are common and generally not harmful, elevated concentrations pose significant health risks.​

When inhaled, radon decay products emit ionizing radiation that can damage lung tissue over time, increasing the risk of lung cancer. According to Health Canada, radon exposure is the leading cause of lung cancer among non-smokers and the second leading cause overall, accounting for approximately 16% of lung cancer deaths in the country.

The risk is particularly pronounced during colder months when homes are sealed to conserve heat, reducing ventilation and allowing radon to accumulate to higher levels indoors. Basements and lower-level rooms are especially susceptible due to their proximity to the ground and potential for limited airflow.​

Given these factors, it's crucial for homeowners to test their homes for radon, especially in regions known for higher radon prevalence. Professional testing can accurately assess radon levels, and if elevated concentrations are detected, mitigation measures can be implemented to reduce exposure and safeguard health.

Why Are Edmonton Homes More Vulnerable to Radon?

Edmonton homes are at a heightened risk of high Radon levels for multiple reasons. The region's geology naturally gives off higher Radon gas concentrations, from the bedrock type to the soil composition. Also, Edmonton's climate keeps homes sealed tightly during long winter months to conserve heat, trapping Radon inside. While older homes with foundation issues are particularly at risk, even new, energy-efficient builds are susceptible due to reduced air exchange. Radon levels can be higher in insulated and energy-efficient homes due to reduced air exchange.

How much Radon is there in Edmonton?

Over the last 10 years, a mounting collection of research findings and testing data has pointed to high levels in Edmonton, some of Canada's highest levels. Alarmingly, some houses have tested levels many times greater than this threshold, which shows the importance of widespread awareness and proactive testing. This isn't just a statistic; it's a red flag for homeowners to do something about it.

Importance of Radon Testing Edmonton Services

Radon is a colourless and odourless gas. The only way to know if your home is safe is to have it tested professionally. Professional Radon Testing Edmonton services provide reliable measurement of Radon levels using calibrated equipment.

How and When to Test Your Home for Radon

The best time for Radon testing is the colder months, usually between October and April, when houses are closed, and there is still air pressure, which could create potential pathways for Radon entry. A long-term test for at least 90 days is ideal for the most accurate results. Testing involves placing a small device in the lowest occupied level of your home, such as the basement, and leaving it undisturbed. You then send the device to a C-NRPP-recognized lab for analysis after the tests. A certified Radon tester will perform the entire process for you and deliver results you can act on.

How to Read Your Radon Test Results

When testing is over, understanding the results is crucial. If it's lower than 200 Bq/m³, your home doesn't need action, although retesting periodically is always recommended. However, if levels exceed the guideline, mitigation is strongly recommended. According to Health Canada, results between 200 and 600 Bq/m³ should be mitigated within two years, while levels above 600 Bq/m³ require action within one year. There is no need to panic; high Radon levels can be effectively mitigated.

What to Do If Your Home Has High Radon Levels

If you find high levels of Radon in your home, the next step is Radon mitigation. The best way is active soil depressurization, which uses a system of pipes and a fan to pull Radon underneath your home to be safely vented outdoors. Such a system can usually lower Radon levels by over 90%. Other techniques include sealing foundation cracks or boosting home ventilation. A certified mitigation contractor will evaluate your home's needs and tailor a working, efficient system. Timely mitigation significantly reduces health risks and restores healthy indoor air quality.

How to Choose a Certified Radon Testing Edmonton Company 

When addressing radon concerns in your home, it's crucial to choose a reputable provider who will clearly explain your options and guide you through the mitigation process if necessary. Certified professionals adhere to national guidelines, utilize calibrated equipment, and deliver accurate reporting to ensure your home's safety.​

Opt for companies with experience in the Edmonton area, as they possess a deeper understanding of the region's unique geological factors that contribute to radon risks. Local expertise ensures more effective testing and mitigation strategies tailored to your home's specific needs.​

Before making a decision, review customer feedback, verify credentials, and confirm that the provider offers both testing and mitigation services.
