Understanding Radon Levels in Innisfail: What the Recent Test Results Mean
In the winter of 2023, 27 homes in Innisfail were tested for radon gas over a 91-day period. The results, while concerning, did not come as a surprise to experts. Elevated levels of radon were detected in some of the homes, highlighting a broader issue in Alberta that has been known for some time.
What is Radon, and Why Should You Care?
Radon is a naturally occurring radioactive gas that is produced by the decay of uranium found in rocks and soil. Because it is a gas, radon can move freely through the ground and into the atmosphere, but it can also seep into buildings. The danger of radon lies in its radioactive properties. Prolonged exposure to high levels of radon has been associated with an increased risk of developing lung cancer. In fact, Health Canada has identified radon as the second leading cause of lung cancer after smoking.
The Canadian government has set a guideline for radon levels inside homes at 200 becquerels per cubic metre (Bq/m³). If levels exceed this guideline, it is recommended that homeowners take action to reduce the concentration of radon in their homes.
Innisfail's Radon Levels: A Closer Look
The recent radon testing in Innisfail was part of a broader initiative called the 100 Radon Test Kit Challenge, which provided free radon test kits to residents. Out of the 27 homes tested, 15 percent were found to have radon levels above the Canadian guideline. Specifically, 10 homes had radon levels under 100 Bq/m³, 13 homes had levels between 100 and 200 Bq/m³, and four homes had levels exceeding 200 Bq/m³, with the highest reading at 280 Bq/m³.
Pam Warkentin, Executive Director of the Canadian Association of Radon Scientists and Technologists, wasn't surprised by these results. She pointed out that a Health Canada survey conducted in 2010 and 2011 found that about eight percent of homes in Alberta had radon levels above the guideline. So, while the 15 percent figure for Innisfail is above the provincial average, it is not unexpected.
The Importance of Widespread Testing
One of the challenges highlighted by Warkentin is the need for more widespread testing. The 100 Radon Test Kit Challenge provided kits for 100 homes, but only 27 homes were tested. This limited sample size makes it difficult to draw definitive conclusions about the prevalence of radon in the area.
Warkentin emphasized that more data is needed to get a clearer picture of radon levels in Innisfail. “As we start to get closer to 100 participants, we start to see that it actually is consistent with a typical average across the city or the area,” she said. The hope is that by encouraging more residents to test their homes, a more accurate and comprehensive understanding of the situation can be developed.
The Broader Picture: Radon Across Canada
Radon is not just an issue in Innisfail or Alberta. It is a concern across Canada, particularly in the Prairie provinces. In Manitoba, for example, some communities have seen radon levels in 30 percent of homes, with some areas reporting levels as high as 90 percent. In Saskatchewan, the situation is similar, with around 25 to 30 percent of homes testing above the guideline.
The variability in radon levels is largely due to the natural presence of uranium in the soil, which varies from region to region. While no area is entirely free of radon, certain regions are more prone to higher levels.
Mitigating Radon Levels in Your Home
If your home has been tested and found to have radon levels above the guideline, there are steps you can take to reduce the concentration. Radon mitigation typically involves sealing cracks and openings in the foundation to prevent radon from entering, as well as installing ventilation systems to reduce radon levels inside the home.
The cost of radon mitigation can vary, but it is generally considered to be affordable. Warkentin mentioned that the mitigation process is not expensive and is a recommended step for any home with elevated radon levels. Since 2014, the Alberta Building Code has required new homes to be built with a short "radon stub pipe" through the basement floor. This pipe can be used as a connection point for a radon mitigation system if needed.
The Future of Radon Testing in Innisfail
Given the results of the recent testing, the Innisfail municipal council is considering continuing the radon testing program in some form. The administration has been directed to bring back the cost of continuing the radon program to a future council meeting. There is a recognition that more needs to be done to ensure that residents are aware of the risks of radon and have the opportunity to test their homes.
Innisfail Councillor Don Harrison, who was a strong advocate for bringing the 100 Radon Test Kit Challenge to the town, expressed his gratitude to both the Town of Innisfail administration and the organization Take Action on Radon for administering the program. Take Action on Radon is a national initiative funded by Health Canada that aims to raise awareness of radon and encourage testing across the country.
Final Thoughts: Why You Should Consider Testing Your Home
While the initial results from the radon testing in Innisfail may seem alarming, they also serve as an important reminder of the need for awareness and action. Radon is a silent threat that can have serious health consequences, but it is also a threat that can be mitigated with the right information and tools.
If you live in Innisfail or any other area where radon levels may be a concern, consider testing your home. The process is simple, and the results could be life-saving. As more data becomes available, it will become easier to understand the true extent of radon exposure in different regions, and more effective strategies can be developed to protect public health.
In the meantime, taking the initiative to test and, if necessary, mitigate radon levels in your own home is a proactive step that can make a significant difference. Radon may be invisible, but with the right approach, its impact doesn't have to be.
