Understanding Radon: Protecting Your Home and Health
What is Radon?
Radon is a colorless, odorless, and tasteless radioactive gas that occurs naturally from the breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in floors, walls, and foundations. When radon gas is trapped indoors, it can accumulate to high levels, posing serious health risks.
Why is Radon Dangerous?
Radon is the second leading cause of lung cancer after smoking. Prolonged exposure to high levels of radon increases the risk of lung cancer, especially in smokers. Health Canada recommends that radon levels in homes be kept below 200 becquerels per cubic meter (Bq/m³).
How Does Radon Enter Homes?
Radon typically enters homes through:
- Cracks in foundation walls and floors
- Gaps around service pipes
- Construction joints
- Sump pits
Testing for Radon
The only way to determine if radon is present in your home is through testing. Long-term testing (3 months or more) provides the most accurate results. At Doug Tarry Homes (DTH), we offer regular radon testing services to ensure the safety of your home. Additionally, affordable DIY radon test kits are available, or you can choose to hire a certified professional to perform the test for you.
Radon Mitigation
If your home has high radon levels, Doug Tarry Homes will take action to reduce it at no additional cost. This is part of the DTH Difference, reflecting our commitment to building safe and healthy homes. Common methods to lower radon levels include:
- Installing a vent pipe system and fan (sub-slab depressurization)
- Sealing cracks and openings in the foundation
Radon in New Homes
Building a new home with radon-resistant construction techniques can significantly reduce the risk of radon infiltration. Techniques include:
- Installing a gas-permeable layer beneath the foundation
- Using plastic sheeting to prevent gas from entering the home
- Sealing foundation openings and cracks
