Radon Levels in Alberta Homes: Map, Risks & How to Test

Radon is an invisible, odourless gas. As a result, it can build up inside your home without warning. Over time, long-term exposure to elevated radon levels increases health risks. In fact, it is the second leading cause of lung cancer after smoking. This map shows real radon levels measured in homes across Alberta. Because of that, it provides a clear local perspective.

Even nearby homes may have large differences between. This is completely normal. Radon levels are not based on location alone. Instead, they are influenced by construction, ventilation, and air movement over time. As a result, every home behaves differently.

So, the key takeaway is simple. Your home’s radon level cannot be predicted. Therefore, the only way to know is to test. Below, you will learn what this map means. You will also learn what causes radon levels to vary. Most importantly, you will learn how to test your home with confidence.

Radon is present in homes across Alberta. Overall, the data shows that levels can vary significantly. Even so, neighbouring homes can have very different results. Because of this, location alone does not determine your risk. Instead, the only reliable way to understand your exposure is to test your home.

Health Canada recommends action when radon levels exceed 200 Bq/m³. However, no level is completely risk-free. Therefore, testing remains an important part of responsible homeownership (Canada.ca). If you have not tested your home, now is the time to make a plan. After all, a simple test can provide clarity and direction. It helps you understand your risk. In addition, it helps you take the next steps with confidence.

Ultimately, the bottom line is simple. You cannot see or smell radon. But you can measure it. And you can take control of it.
