How Radon Affects Your Building
There are many misconceptions about radon. One of the most common misconceptions is the idea that radon can only enter buildings with basements. The truth is, radon can enter any building where the building is in contact with the underlying soil and/or rock. This means that slab on grade buildings are as susceptible to radon entry as buildings with sub-grade basement levels.
How Radon Enters a Building
Radon can enter both old and new buildings, those that are well-sealed or drafty, and those with and without basements. The most common sources of infiltration include (but are not limited to):
- Cracks or openings in foundation, flooring or walls
- Unsealed joints
- Crawl spaces without proper ground cover
- Open floor drains/sump pits
- Using groundwater that contains radon
Radon can also come into a building via well water but this contribution is typically less significant than radon which comes from soil and/or rock.
Why Test for Radon in a Commercial/Institutional Building?
You wouldn't purchase a building without a thorough investigation of its history, structure and mechanical systems. That same due diligence should also be applied to indoor air quality, including radon testing.
If you currently own or manage a property, radon testing is a cost-effective way to ensure you are providing a safe environment for occupants. Radon testing and mitigation measures can also identify and improve existing mould and odour problems. Radon testing is also recommended for BOMA Best and LEEDS certification.
Why Test for Radon in Your Home?
Nothing is more important than your family's health and safety. Radon testing is easy and inexpensive and when performed by our accredited radon measurement technicians, you receive accurate, timely results. Radon testing should be done as part of the inspection process before purchasing a home, or it can be done in a current residence.
Radon comes from the natural breakdown of uranium in soil, rock and water, which is released into the air. It then becomes trapped inside buildings. Radon can be found throughout Canada and the U.S. in virtually every kind of building – homes, offices, schools, hospitals and other facilities.There is no “safe” level of radon. Potential for exposure is a function of the amount of exposure and time exposed, and the harmful effects of radon exposure can take many years to become evident. In 2005, the U.S. Surgeon General declared that radon was the second leading cause of lung cancer after cigarette smoking.
