Radon is a dangerous, radioactive gas that you can’t see or smell, but it poses a significant risk, contributing to 16% of lung cancer deaths according to Health Canada. In fact, the Canadian Lung Association estimates that 7% of homes in Canada have dangerous levels of radon. The good news? Testing your home for radon is simple, inexpensive, and could save your life.
What is Radon?
Radon is a naturally occurring gas released by the breakdown of uranium in soil, rock, and water. It can enter homes through cracks in the foundation, floors, and walls. Outdoors, radon disperses harmlessly, but indoors it can build up to dangerous levels over time, especially in enclosed spaces like basements.
Why Testing Matters
Long-term exposure to radon increases your risk of lung cancer, particularly if you smoke. Since radon is odorless and invisible, the only way to detect it is through a test. Testing your home for radon ensures that you catch elevated levels before they pose a threat to your health.
How to Test for Radon
There are two types of radon tests:
- Short-term radon tests: These take between two and 90 days, but Health Canada recommends long-term testing for accuracy.
- Long-term radon tests: These take more than 90 days and provide a more reliable reading of your home’s radon levels.
You can buy a radon test kit at most hardware or home improvement stores, or online. Make sure your kit is certified by the Canadian National Radon Proficiency Program, which ensures it meets quality standards set by Health Canada.
How to Use a Radon Test
- Test your home’s lowest living area: If you have a finished basement, place the test there. If you only use the basement for storage, test on the first floor.
- Avoid damp areas: Kitchens, bathrooms, and laundry rooms can affect your results, so avoid these spaces.
- Send the test to the lab: Once the testing period is complete, follow the instructions to send the device to a certified lab for analysis.
Understanding Your Test Results
No level of radon is completely safe, but the Canadian guideline for radon levels is set at 200 becquerels per cubic metre (Bq/m³). If your results are higher than this, it’s time to take action. Even if your levels are between 100 and 200 Bq/m³, it may still be worth fixing for peace of mind.
What to Do if Radon Levels Are High
Hire a qualified radon mitigation contractor who can reduce radon levels in your home. They may recommend installing a radon reduction system to prevent the gas from accumulating. This can involve sealing foundation cracks, improving ventilation, or installing a system that redirects radon outside your home.
Ensuring your home is radon-free is essential for your health and well-being. Talk to a contractor certified in radon mitigation to protect your home and loved ones.
