Whether you've just heard about radon for the first time or you've already received a concerning test result and aren't sure what to do next, you've come to the right place. At Radon Doctors, we believe that an informed homeowner is a protected homeowner, which is why we've put together a comprehensive FAQ list of the most common inquiries we receive. Common Questions Frequently Asked Questions Have more questions about radon, testing, mitigation, and more? We're always happy to explain the science. 01 Why is radon dangerous? The real danger with radon happens when you breathe it in over an extended period of time. When radon gas is inhaled, it decays inside your lungs and releases alpha particles, which are highly energetic radioactive particles that can damage the DNA in lung tissue cells. This DNA damage, accumulated over months and years of exposure, can lead to mutations that trigger the development of lung cancer. Radon is officially classified as the #1 cause of lung cancer among non-smokers in Canada and the second leading cause of lung cancer overall, responsible for approximately 3,200 Canadian deaths every year. The risk increases significantly when radon exposure is combined with cigarette smoking, making mitigation even more critical for smokers or households with smokers. The danger is entirely preventable - which is why testing and mitigation... --- - Published: 2026-04-02 - Modified: 2026-04-02 - URL: https://radon-doctors.ca/book-your-free-test/ Contact The Radon Doctors for Your Free Radon Test Book your free residential radon test with our team of experts.

At Radon Doctors, we provide commercial radon system repair and fan replacement across Calgary and Alberta, ensuring your radon mitigation system continues to perform at peak levels. radon repair process What Happens During a Commercial Radon System Repair? Many commercial property owners assume that once a radon mitigation system is installed, there's nothing left to worry about. In reality, radon mitigation systems, especially in larger commercial buildings, are mechanical systems that require ongoing attention to maintain peak performance. Over time, fans can degrade, pressure differentials can shift, ductwork can develop issues, and building changes (like renovations or HVAC modifications) can alter how radon moves through the space. System performance assessment: We measure fan output, sub-slab pressure, and airflow. Fan inspection and replacement: We evaluate whether existing fans are operating correctly. Pipe and seal integrity checks: We identify any cracks, gaps, or disconnections. Post-repair radon testing: We confirm radon levels have returned within guidelines. Documentation and reporting: We provide clear, written results for your records, insurance, or tenant disclosure needs. radon system maintenance How Often Should a Commercial Radon Mitigation System Be Maintained?

Radon Doctors provides certified residential radon testing across Calgary and surrounding areas, offering accurate, science-backed results - and clear guidance on what to do next. measuring radon in your home What Does a Residential Radon Test Actually Measure? Radon is a naturally-occurring radioactive gas that forms when uranium in soil and rock breaks down. It seeps through foundation cracks, floor joints, and other openings and accumulates in the lower levels of your home. A residential radon test measures the concentration of radon gas in your home's air, expressed in Becquerels per cubic metre (Bq/m³). Health Canada's guideline for acceptable radon levels is 200 Bq/m³ - anything above this threshold indicates that mitigation should be considered. Radon testing includes: Placement of a certified long-term or short-term radon detector in the lowest livable area of your home A testing period that captures an accurate reading of your radon levels Collection and laboratory analysis of the detector or digital readings A clear, easy-to-understand report of your radon levels A professional and honest recommendation, based on your results radon testing timeline How Long Does Radon Testing Take? The duration of a radon test depends on the method used.

Radon System malfunction What Are Signs My Radon Mitigation System Isn't Working? A radon mitigation system that isn't functioning properly isn't just an inconvenience - it's a health risk. Health Canada has established a guideline of 200 Bq/m³ as the action level for radon in Canadian homes, and a failed or underperforming mitigation system can cause indoor radon levels to climb above that threshold, without any visible warning signs. The following issues may warrant a radon mitigation system repair: There's visible damage to piping, seals, or exterior components from weather or age The system's fan has stopped running - no airflow means radon levels can rise back up The visual indicator (u-tube or gauge) shows no pressure - a sign the system may no longer be drawing radon Unusual noises are coming from the fan, such as grinding, rattling, or humming You've received high radon test results despite having a mitigation system in place Your system is 5+ years old and has never been inspected or serviced radon fan replacement What Does a Radon Fan Do?

Crawl space encapsulation is the process of sealing this area - and controlling moisture, blocking soil gases (like radon), and improving your air quality in the process. At Radon Doctors, we approach crawl space encapsulation the way we approach everything: with a diagnostic mindset, certified expertise, and a commitment to solutions that actually work. crawl space encapsulation What Is Crawl Space Encapsulation? Why Is It Important? Crawl space encapsulation involves installing a heavy-duty vapour barrier across the floor and walls of your crawl space, effectively sealing it off from the soil beneath. This creates a controlled environment that limits moisture intrusion, reduces the risk of mold and structural damage, and helps block the primary pathway through which radon and other soil gases enter your living space. In Calgary and across Alberta, homes built over crawl spaces are at risk of experiencing elevated radon levels, making encapsulation an important part of improving indoor air quality. Without encapsulation, you could face: Mold and mildew growth on interior home surfaces Radon entering through soil gaps, cracks, and porous materials Higher heating and cooling costs due to poor air sealing Musty odours circulating through your living areas Deterioration of floor joists, subfloor materials, and insulation Worsened indoor air quality that can impact respiratory health over time... --- > Our commercial radon services are designed to protect your property, your people, and your peace of mind.

At Radon Doctors, we bring a data-driven approach to commercial radon mitigation across Calgary and Alberta, designing systems that are built to perform effectively and keep your space safer. commercial radon mitigation What Does Commercial Radon Mitigation Involve? Commercial radon mitigation is the process of installing a professionally designed ventilation system that draws radon gas from beneath a building's foundation and safely expels it outside - well before it can accumulate to harmful levels indoors. Unlike residential mitigation, commercial projects require a more diagnostic approach because the buildings are larger, more structurally complex, and often occupied by many people for long hours each day. At Radon Doctors, every commercial mitigation project begins with a thorough site assessment and ends with post-mitigation testing to confirm the system is working as intended.

Contact Radon Doctors to ensure safe indoor air. - Published: 2026-05-31 - Modified: 2026-05-12 - URL: https://radon-doctors.ca/resource/buying-a-home-why-you-should-never-skip-the-radon-test/ You’ve finally found it—the perfect house. The layout is exactly what you wanted, the neighborhood is great, and the natural light is stunning. Now comes the stressful part: the paperwork, the mortgage approval, and the home inspection. When you are already paying for a general inspection, a pest inspection, and maybe even a sewer scope, it can be tempting to cross that optional "radon test" off the list to save a few bucks. However, skipping this vital step is a gamble you shouldn't take. Here is everything you need to know about radon and why testing for it is a non-negotiable step in the home-buying process. What Exactly is Radon? Radon is a naturally occurring, radioactive gas. It is produced by the natural breakdown of uranium found in soil, rock, and water. Because the air pressure inside your home is usually lower than the pressure in the soil around your home's foundation, your house acts like a vacuum, drawing radon gas in through foundation cracks, construction joints, and gaps around service pipes. The most dangerous thing about radon? It is completely invisible, odorless, and tasteless. The only way to know if a home has high levels of radon is to test for it. The Real Health Risks It is easy to brush off invisible threats, but the scientific and medical consensus on radon is clear and sobering. Leading Cause of Lung Cancer: Radon is the number one cause of lung cancer among non-smokers. A Major Aggravator: If you smoke and... --- > Confused by your radon report? Learn how to understand your radon test results, decode Bq/m³ measurements, and know when Health Canada recommends mitigation. - Published: 2026-05-24 - Modified: 2026-05-12 - URL: https://radon-doctors.ca/resource/how-to-read-and-understand-your-radon-test-results/ Waiting for radon test results can be nerve-wracking. You’ve taken the right step to protect your home and your lungs, but when that report finally arrives, it often looks like a jumble of scientific jargon and confusing numbers. Don't panic. Understanding your radon test results is actually quite straightforward once you know what the measurements mean and where the safety thresholds lie. Let’s break down your report so you know exactly what your next steps should be. Demystifying the Measurements: Bq/m³ vs. pCi/L Depending on where you live and the testing lab you used, your radon levels will be reported in one of two units. Since we are looking at this from a Canadian perspective (hello, Calgary! ), we will focus heavily on the Canadian standard, but it is helpful to know both. Becquerels per cubic meter (Bq/m³): This is the standard unit of measurement used in Canada by Health Canada, as well as by the World Health Organization (WHO). Picocuries per liter (pCi/L): This is the standard measurement used in the United States by the Environmental Protection Agency (EPA). Quick Conversion Rule: 1 pCi/L is equal to 37 Bq/m³. The Action Levels: When Should You Worry? Radon is a naturally occurring gas, meaning there is no such thing as a "zero" radon environment. The outdoor air typically has a background radon level of about 15 Bq/m³ (0. 4 pCi/L). The goal isn't to eliminate radon completely, but to keep it below established health guidelines. Here is how to interpret... --- > We provide everything you need to know - how radon enters your home, how radon mitigation systems work, and what to expect during the mitigation process. - Published: 2026-05-11 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/does-your-homes-radon-level-change-with-the-weather/ If you are a homeowner, you have likely heard about radon. It is an invisible, odorless, and naturally occurring radioactive gas that can seep into your home from the soil beneath your foundation. It is also the second leading cause of lung cancer. But there is a common misconception that once you test your home for radon, that number is set in stone. The reality is that radon levels are dynamic. They fluctuate from day to day and month to month. One of the biggest drivers of these changes? The weather outside. Here is a look at how different seasons and weather patterns can affect the radon levels in your house—and why understanding this is crucial for your family's health. 1. Winter and "The Stack Effect" Winter is notoriously the time when indoor radon levels hit their peak. This is largely due to something called the "stack effect. " When the temperature drops, you turn on your heating system. As the warm air inside your house rises and escapes through the upper levels and attic, it creates a vacuum effect (negative pressure) in the lower levels of your home, like your basement or crawlspace. This vacuum literally sucks the soil gases—including radon—up through the cracks in your foundation and into your living space. Combined with the fact that our windows stay tightly shut all winter, that trapped gas has nowhere to go. 2. Rain and the "Capping Effect" Have you ever noticed how a dry sponge absorbs water, but a... --- > We provide everything you need to know - how radon enters your home, how radon mitigation systems work, and what to expect during the mitigation process. - Published: 2026-05-11 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/can-an-air-purifier-remove-radon-the-truth-about-hepa-filters/ Radon is a word that often strikes fear into the hearts of homeowners, and for good reason. It’s an invisible, odorless, and tasteless radioactive gas that occurs naturally in the environment. But when it gets trapped inside our homes, it becomes a serious health hazard. In fact, radon is the second leading cause of lung cancer worldwide, right behind smoking. With indoor air quality becoming a top priority for many, a common question arises: Can my air purifier protect me from radon? Specifically, do HEPA filters remove radon gas? Let's break down the science. What Exactly is Radon? Radon is produced by the natural radioactive decay of uranium found in soil, rock, and groundwater. As the uranium breaks down, it releases radon gas, which slowly makes its way up to the surface. Outdoors, radon disperses rapidly into the atmosphere and isn’t a threat. However, when it seeps into buildings through cracks in the foundation, gaps around pipes, or poorly sealed crawl spaces, it can become trapped and accumulate to dangerous levels. The Danger: Radon Progeny To understand how filters work against radon, we have to understand the life cycle of the gas. The true danger of radon isn’t just the gas itself, but what it turns into. As radon gas decays in the air, it produces solid radioactive particles known as "radon progeny" or "radon daughters" (such as polonium, lead, and bismuth). These tiny, electrically charged particles easily attach to airborne dust, smoke, and PM2. 5. When you breathe them... --- > We provide everything you need to know - how radon enters your home, how radon mitigation systems work, and what to expect during the mitigation process. - Published: 2026-05-11 - Modified: 2026-05-12 - URL: https://radon-doctors.ca/resource/the-invisible-connection-radon-particulate-matter-and-your-lungs/ When we talk about air quality, we often treat Radon and Particulate Matter (PM) as two separate chapters in a textbook. However, in the context of lung cancer, they are more like partners in crime. Understanding the relationship between these two is vital for anyone looking to ensure a truly healthy indoor environment. The Decay Chain: From Gas to "Progeny" Radon is a naturally occurring radioactive gas that seeps into homes from the soil. On its own, radon is chemically inert—you breathe it in, and you breathe most of it right back out. The real danger lies in its progeny (also known as radon decay products or "radon daughters"). As radon gas decays, it transforms into solid radioactive particles of Polonium, Lead, and Bismuth. Unlike the gas, these solids are electrically charged. This charge makes them "sticky," leading to two possible paths: Unattached Fraction: The particles remain tiny and free-floating. Attached Fraction: The particles immediately "hitch a ride" by clinging to particulate matter (dust, smoke, or aerosols) already present in the air. Why Particulate Matter Changes the Stakes The presence of dust or smoke in a room acts as a delivery system for radiation. Here is why the "Attached Fraction" is so hazardous: Deep Lung Penetration: Particulate matter, especially $PM_{2. 5}$ (fine particles), is the perfect size to bypass the body's natural filters and settle deep into the lung tissue (the bronchial epithelium). Localized Radiation: Once a dust particle laden with radon progeny lodges in your lung, it stays there.... --- > We provide everything you need to know - how radon enters your home, how radon mitigation systems work, and what to expect during the mitigation process. - Published: 2026-05-11 - Modified: 2026-05-12 - URL: https://radon-doctors.ca/resource/the-silent-threat-why-your-radon-dose-matters-more-than-your-radon-level/ If you’ve recently tested your home for radon, you likely received a number—perhaps something like 2. 5 pCi/L or 4. 2 pCi/L. For most homeowners, the immediate reaction is to check that number against the Environmental Protection Agency (EPA) action limit of 4. 0 pCi/L. If it’s below that line, you breathe a sigh of relief. If it’s above, you call a mitigator. But looking only at the radon level is a flawed way to view your actual health risk. To truly protect your family from this cancer-causing gas, you need to understand the critical difference between Radon Level and Radon Dose—and why a "low" level doesn't always mean you are safe. Radon Level vs. Radon Dose: The Car Analogy To understand the difference, let’s use a simple driving analogy: ConceptThe Driving AnalogyWhat it Means for RadonRadon LevelYour Speed (MPH)How much radioactive gas is currently in the air of a specific room. Radon DoseTotal Distance TraveledThe total, cumulative amount of radiation your lungs have absorbed over time. The Radon Level is a snapshot. It tells you the concentration of gas in a specific space at a specific time. The Radon Dose is your actual exposure. It is calculated by multiplying the radon level by the amount of time you spend in that environment. Dose is the metric that actually dictates your risk of developing lung cancer. Why Dose is the True Measure of Danger Radon gas decays into radioactive particles that get trapped in your lungs when you breathe.

But there’s another invisible, odorless, and tasteless gas that could be lingering in your home: Radon. Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil and rock. When it escapes from the ground into the outdoors, it dilutes harmlessly. However, when it seeps into a home through foundation cracks, pipe gaps, or sump pumps, it can accumulate to dangerous levels. The good news? Testing for radon is incredibly easy, and you can do it yourself. Here is everything you need to know about checking your home’s radon levels. How to Test: Your Two Best Options When it comes to DIY radon testing, homeowners generally have two highly effective options to choose from: 1. Continuous Radon Monitors (CRMs) If you love tech and want to see how your radon levels fluctuate day-to-day, a Continuous Radon Monitor (CRM) is a great choice. These electronic devices give you a digital readout of your home’s air quality and often connect to smartphone apps. However, not all electronic monitors are created equal. It is highly recommended that you use a device that has been tested and certified by the Canadian National Radon Proficiency Program (C-NRPP). This ensures the device is accurate and reliable. You can find a list of C-NRPP-approved consumer-grade electronic monitors here: https://c-nrpp. ca/consumer-grade-electronic-radon-monitors/ 2.

You can't see it, smell it, or taste it, yet it is the second leading cause of lung cancer worldwide. To understand why this natural gas is so dangerous, we have to look closely at what it releases when it breaks down: a tiny, energetic piece of radiation known as an alpha particle. While "radiation" sounds like a broad, scary term, alpha particles are actually quite unique. Understanding how they act is the key to understanding why radon is such a specific threat to our lungs. What is an Alpha Particle? (The "Microscopic Cannonball") In the world of radiation, alpha particles are the heavyweights. Compared to other types of radiation (like beta particles or gamma rays), alpha particles are massive and relatively slow. Because of their size, they don't penetrate very far. In fact, an alpha particle can be completely stopped by a single sheet of paper, or even the top, dead layer of your skin. If a radon atom decays outside your body, the alpha particle it shoots out is completely harmless to you. The danger only begins when you breathe it in. When radon gas gets trapped in your home, you inhale it with every breath. If a radon atom decays while it is inside your lungs, it fires that heavy, energetic alpha particle directly into your soft, vulnerable, and very much alive lung tissue. Because alpha particles can't travel far, they dump 100% of their destructive energy into a tiny, concentrated area... --- - Published: 2026-04-05 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/waterborn-radon-mitigation/ Discovering that your home’s well water contains radon can be a stressful moment for any homeowner. It’s natural to feel worried—radon is a naturally occurring, invisible, and odorless radioactive gas that poses serious health risks, primarily lung cancer. But take a deep breath: radon in well water is completely treatable. While most people know about radon seeping through basement cracks, well water can also carry radon gas into your home. When you run the shower, do the laundry, or wash dishes, the agitation releases the trapped radon gas into your indoor air. Because the primary danger of radon is inhalation rather than ingestion, treating it requires a "whole-house" or Point-of-Entry (POE) system. Point-of-Use filters (like a pitcher or under-sink filter) won't solve the air contamination problem. If your well water has tested high for radon, here are the two standard, proven methods for removing it before it ever reaches your taps, along with the pros and cons of each. Method 1: Aeration Systems (The Gold Standard) Aeration is widely considered the most effective and safest method for treating radon in water, especially for homes with high levels of contamination. How it Works: An aeration system is installed where the water first enters your home. Inside the unit, water is sprayed, bubbled, or cascaded through air. Because radon is a gas dissolved in the water, this aeration process forces the radon to separate from the water. An exhaust fan then captures the released radon gas and safely vents it outside your... --- - Published: 2026-03-29 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/waterborne-radon/ When we think about radon gas sneaking into our homes, we usually picture it seeping up through cracks in the basement floor or gaps in the foundation. But there’s another, often-overlooked pathway that this invisible, odorless gas can take: your water supply. If you get your water from a private well, everyday activities like taking a hot shower, running the dishwasher, or even washing your hands could be releasing radon gas directly into the air you breathe. Here is a breakdown of how this happens, the correlation between radon in your water and air, and how to find out if your plumbing is the culprit. How Does Radon Get From the Sink to the Air? Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. When groundwater flows through these rocks, radon gas can dissolve into the water. If your home relies on a private well, that water gets pumped straight into your plumbing system, carrying the trapped radon with it. The radon stays trapped in the water while it’s enclosed in your pipes. But the moment that water is released and agitated, the gas escapes into the surrounding air. Think of it like opening a shaken bottle of soda. The carbon dioxide is trapped while the cap is on, but once you open it and pour, the bubbles aggressively escape. The same thing happens with radon-rich water when it goes through: The Shower: The spraying action of the showerhead, combined with the... --- - Published: 2026-03-22 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/radon-toenails/ What if something as simple as a toenail clipping could help detect your risk of lung cancer? That’s exactly what scientists at the University of Calgary are exploring in a groundbreaking new study—and it could change how we understand radon exposure forever. The Hidden Danger: Radon Gas Radon is an invisible, odorless, and radioactive gas that naturally forms in the ground. When it accumulates inside homes, it becomes a serious health risk. In fact, radon is the second leading cause of lung cancer after smoking. But unlike smoking, most people have no idea how much radon they’ve been exposed to over their lifetime. Why Toenails? It may sound surprising, but your toenails act like a biological archive. Researchers have found that toenails can store traces of radioactive materials—specifically lead isotopes that form after radon is inhaled. Because toenails grow slowly, they preserve long-term exposure data, giving scientists a unique way to measure radon exposure over time. A Nationwide Study The research team is aiming to collect up to 10,000 toenail samples from Canadians. Participants are asked to test their homes for radon and submit toenail clippings for analysis. By combining these two steps, scientists can connect real-world radon levels inside homes with biological evidence found in the body. Why This Matters Right now, lung cancer screening is mostly based on smoking history. However, a surprising number of people diagnosed with lung cancer don’t meet current screening criteria. Many of them have never smoked, or they smoked too little or too... --- - Published: 2026-03-17 - Modified: 2026-04-15 - URL: https://radon-doctors.ca/resource/is-long-term-radon-testing-more-accurate/ When it comes to radon testing, one of the most common questions we hear is: "Does it matter how long I test for? " The short answer is yes - and the difference between short-term testing and long-term radon testing can be significant. Whether you own a home in Calgary or manage a commercial property in Alberta, understanding the distinction between short-term and long-term radon testing could be one of the most important health decisions you make. What Is Radon & Why Does Testing Matter? Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It's invisible, odourless, and tasteless - which means you have no way of detecting it without proper testing. In Canada, radon is the leading cause of lung cancer among non-smokers. The Health Canada guideline for radon levels is 200 Bq/m³ - any property testing above this threshold should have a mitigation system installed to reduce exposure. That said there is no "safe" level of radon, so the goal should be to maintain as low of levels as possible. Alberta (and Calgary in particular) sits on geology that makes elevated radon levels more common than many people realize. That's why testing isn't just a good idea here - it's essential. Short-Term vs. Long-Term Radon Testing: What's the Difference? What's the difference between short-term and long-term radon testing? And which is the best option for your situation?

It has no colour, no smell, and no taste - yet it's the second leading cause of lung cancer in Canada. For Calgary homeowners, radon is a very real, very local concern that deserves serious attention. This guide will walk you through everything you need to know about radon and radon reduction - how radon enters your home, how radon mitigation systems work, and what to expect during the mitigation process. What Is Radon & Where Does It Come From? Radon is a naturally occurring radioactive gas produced by the gradual decay of uranium in soil and rock. As uranium breaks down, it produces radium, which further decays into radon gas. That gas migrates upward through the soil and, under normal circumstances, safely disperses into the open air. The problem with radon exposure begins when it enters an enclosed structure - like your home. Once inside, radon continues to buildup, releasing radioactive particles that can be inhaled deep into lung tissue. Over years of exposure, this radiation damages cells and significantly increases the risk of developing lung cancer. In fact, radon is the 2nd leading cause of lung cancer in the country. What Is Radon Mitigation? How Does Radon Mitigation Work? The goal of radon mitigation is straightforward: prevent radon gas from entering your home and dilute or remove any that does. Radon mitigation works by changing the air pressure dynamics between the soil beneath your home and the indoor air inside it. By creating... --- > High radon levels are the leading environmental cause of lung cancer. Health Canada has established a national guideline that provides clear thresholds. - Published: 2026-03-17 - Modified: 2026-04-15 - URL: https://radon-doctors.ca/resource/what-radon-levels-are-considered-dangerous-in-alberta/ Radon is a naturally-occurring radioactive gas that is invisible, odourless, and naturally present in the air - it's also one of the most overlooked and underestimated health risks in Canadian properties. When you breathe in radon, it decays into radioactive particles that can become lodged in your lung tissue. Because of this, high radon levels have been recognized as the leading environmental cause of lung cancer in Canada, including the Calgary, AB area. Once inside a home or business, particularly in a basement or lower level, radon can accumulate to dangerous concentrations. The problem isn't a single breath of radon-laden air. The real danger lies in long-term, repeated exposure over months and years. What Measurement Is Used for Radon in Canada? In Canada, radon concentrations are measured in Becquerels per cubic metre (Bq/m³). A Becquerel represents one radioactive decay event per second, and the "per cubic metre" portion reflects the concentration of that radioactive activity within a given volume of air. This is the standard unit used by Health Canada, the Canadian National Radon Proficiency Program (C-NRPP), and all certified radon professionals operating across the country. When you receive the results from a radon test, your reading will be expressed in Bq/m³. What Does Health Canada Say About Radon Levels? Health Canada has established a national radon guideline that provides clear thresholds for residential settings and business establishments. Below 200 Bq/m³: No immediate action is technically required, however, Health Canada emphasizes that there is no truly "safe" level of radon... --- - Published: 2026-03-15 - Modified: 2026-05-11 - URL: https://radon-doctors.ca/resource/we-are-now-bbb-accredited/ Exciting News from Radon Doctors!

It’s the reality of Radon Gas in the Calgary area. While many Calgarians are aware of the dangers of carbon monoxide, very few realize that the soil their beautiful home is built upon is releasing a radioactive gas that is the second leading cause of lung cancer overall, and the #1 cause among non-smokers.

The Calgary Profile: Why We Are at Risk Calgary—along with much of Southern Alberta and the Canadian Prairies—is situated on geology that is naturally rich in uranium. As uranium simplifies and decays in the soil over thousands of years, it produces radon gas. Because radon is a gas, it rises. It eventually finds its way to the surface, where it would normally dilute harmlessly into the atmosphere. The problem is our homes.
