Radon is a dangerous, naturally occurring gas that can enter your home without any visible signs. Understanding how radon gets in your home is crucial for protecting your family’s health, as prolonged exposure to high radon levels can increase the risk of lung cancer. Since the gas is odourless, colourless, and tasteless, the only method to find it is to test for its presence. At Synergy Radon, we specialize in radon testing and mitigation to help you keep your home safe and your loved ones protected.
What is Radon?
The breakdown of uranium in soil, rock, and water produces radon, a naturally occurring radioactive gas. It is completely invisible—colourless, odourless, and tasteless—making it impossible to detect without specialized testing. Radon gas can seep into homes through cracks in the foundation, construction joints, and gaps around pipes, gradually accumulating in enclosed spaces, especially basements and crawl spaces.
Health Impacts of Radon Exposure
Radon is the leading cause of lung cancer in non-smokers. Health Canada advises that indoor radon levels should be below 200 becquerels per cubic meter (Bq/m³), whereas the World Health Organization recommends levels below 100 Bq/m³. Buildings that test above this level should take immediate steps to reduce radon exposure through professional mitigation services like those offered by Synergy Radon. Protecting a home, workplace, and school from radon is essential to maintaining a healthy living environment.
Why Homes Are Vulnerable to Radon Accumulation?
Radon gas exists naturally in the earth beneath homes and can accumulate in enclosed spaces over time. The design, age, and condition of a building all influence how much radon enters and where it concentrates. Factors such as structural design and layout, ventilation systems, and environmental conditions, particularly in radon-prone regions like the Okanagan Valley, increase the risk of radon entering your home. Knowing how radon enters your home will help you identify weak points and take preventive measures to minimize exposure. However, it is important to remember that radon gas cannot be sealed out of a building, so although sealing of cracks, gaps, and penetrations are important, it is only part of the mitigation strategy, for if the pressure below the building is not addressed, radon continues to push its way in, even through the concrete itself. Nevertheless, some of the most common entry points include:
- Foundation and Floor Slab Cracks, and Construction Gaps—Cracks in the foundation, poorly sealed concrete cold joints, and openings caused by curing concrete and settling can create direct pathways for radon to enter. These areas can allow radon-rich soil gas to seep into buildings where it can accumulate to hazardous levels.
- Unsealed Pipes and penetrations—Homes often have gaps around service pipes, utility lines, and sump pits, which are commonly overlooked. Unsealed openings provide radon gas with additional entry points, especially in older homes where caulking and seals may have deteriorated over time.
- Basements, Crawl Spaces, and Slab-on-Grade Floors—Homes of any type can and will have radon; the questions is, how much?
- Soil Composition in the Okanagan Region—The Okanagan Valley’s geology is known for its uranium-rich deposits, increasing the likelihood of radon emissions. Homes built in these areas are more susceptible to radon infiltration as the gas naturally rises through the porous ground or fissures in bedrock.
- Seasonal Shifts (Cold Weather, Sealing Homes Tightly in Winter)—During colder months, homes are often sealed to retain heat, reducing ventilation. This increases indoor radon levels as the gas becomes trapped with no means of escaping. Additionally, the pressure difference between the warmer indoor air and the cooler outdoor soil draws more radon into the home, exacerbating the issue.
Testing for Radon Levels
Since radon is invisible and undetectable without specialized tools, testing is the only way to determine if your home has elevated radon levels. Regular testing helps you stay informed about your indoor air quality and protect your family from long-term health risks. Occupants can choose between consumer grade digital radon detectors, short-term test kits, long-term test kits, and professional radon testing services.
Consumer grade digital radon detectors are an option that provide occupants with rapid response radon detection. Some detectors provide accurate results in as little as 1 hour. However, not all digital radon detectors are created equal, and some are more accurate than others. It is recommended that occupants combine the use of digital radon detectors with that of a C-NRPP Listed short-term or long-term radon test, to verify the accuracy of the digital detector.
Short-term radon tests measure radon levels over a period of 2 to 90 days and can provide a quick snapshot of radon concentrations. While convenient, short-term tests may not provide an accurate average, especially during seasonal shifts when radon levels fluctuate. Health Canada recommends a long-term radon test of at least 91 days in the winter, and that the decision to mitigate a building should be made from long-term test data. A C-NRPP Listed short-term radon detector is strongly recommended for its accuracy and quality control protocols that must be followed to ensure a fresh detector every time.
Long-term radon testing is any test 91 days or more, ideally conducted over the winter months as this is when radon is most often at its highest indoors. Winter is when buildings are sealed up, and pressure is greatest beneath the building due to convection (stack effect), pushing more radon gas inside. Long-term tests provide greater accuracy. C-NRPP Listed long-term radon detector is strongly recommended for its accuracy and quality control protocols that must be followed to ensure a fresh detector every time.
Professional radon testing services are provided by a C-NRPP Certified Radon Measurement Professional. This Canadian Professional can recommend and conduct the best test based on your individual needs and time constraints. Options can include digital detectors, C-NRPP Listed short-term radon detectors, C-NRPP Listed long-term radon detectors, and C-NRPP Listed and annually calibrated Continuous Radon Monitors (CRMs), which provide industry standard reporting, including hourly average radon levels, and can include additional data, such as temperature, barometric pressure, and even anti-tampering features. A professional CRM is best used when testing a building for a short duration, for example, during a real estate transaction, as a diagnostics tool to determine when radon levels are highest, or possible ventilation concerns, or for a follow-up radon upon completion of a radon mitigation. When it is for your family’s health and safety, a Certified Radon Measurement Professional can ensure you have the ideal radon test conducted for your situation.
How to Prevent and Mitigate Radon in Your Home
If your home tests for elevated radon levels, implementing radon mitigation strategies is essential to protect your family’s health. Fortunately, several proven methods can reduce radon concentrations and prevent the gas from accumulating indoors. Below are the most effective steps for radon prevention and mitigation:
Sealing Gaps and Cracks
One of the simplest ways to reduce radon entry is by sealing cracks, gaps, and openings in your home’s foundation and walls. This includes:
- Sealing cracks in the basement floor and foundation walls
- Closing gaps around pipes, sump pits, and construction joints
- Applying caulk or specialized sealant to fill smaller holes and seams
While sealing can help reduce radon levels, it is generally not sufficient on its own to drastically lower radon levels, especially in homes with high radon concentrations; however, it plays an important role in supporting primary mitigation methods: Active Soil Depressurization (ASD).
Installing a Radon Mitigation System (Active Soil Depressurization)
Active Soil Depressurization (ASD) is the most effective and widely used radon mitigation method. This system works by drawing radon gas out from beneath the home before it enters the living space, meanwhile lowering the pressure below the building, relative to the pressure in the building. Key components of an ASD system include:
- A suction pipe: Inserted through the concrete floor slab or crawlspace ground membrane
- Air pressure and air flow “diagnostics”: A specialized process with unique tools that allow Certified Radon Mitigation Professionals to design, using pressure and flow data, a precise radon mitigation system for a specific situation within a specific building.
- A fan system: Installed to create a vacuum below the building, while air pressure and flow “diagnostics” are utilized to determine if vacuum has been achieved below the entire footprint of the living space.
- An exhaust vent: Discharges the air captured from below the building into a safe area, determined by exhaust clearance guidelines. Both sidewall exhausts and roof top exhausts are allowable in Canada.
When to Retest Your Home for Radon
Retesting is crucial to ensure that your mitigation system is working effectively and that radon levels remain low. Ensure retesting is conducted:
- After installing a mitigation system to confirm its effectiveness
- Every 2 to 5 years, even if previous tests showed low radon levels
- After significant home renovations, such as window and door upgrades, furnace or water heater replacements or upgrades, and building envelope upgrades, or additions or major changes to the building.
Regular monitoring provides peace of mind and ensures your family continues to live in a safe environment.
