In a Winnipeg bungalow, the finished basement may be where the family watches movies, works from home or puts guests up overnight—yet radon leaves no smell, haze or obvious warning. Opening a window once or relying on a single short test will not necessarily settle the question, because readings can shift with ventilation, HVAC use and changing home conditions. A detector left in the lowest lived-in level gives a clearer picture in Bq/m³, the unit used in Health Canada’s 200 Bq/m³ reference level. And while our [top air purifiers for Canadian homes](https://www.thecanadareport.ca/best-air-purifiers-for-canadian-homes/) can help tackle particles and odours, they do not measure or remove radon. This curated guide sorts ongoing digital monitors from long-term lab kits, running from about $76 for a straightforward display up to roughly $279 for a smart multi-sensor model. Our leading pick for most households is the **Airthings Corentium Home** (Canadian version, in Bq/m³): it combines a simple display, short- and long-term averages, a 4.6-star rating from about 2,900 reviews and a price of $142.99\. One thing worth checking before you order: radon devices are certified in Canada through C-NRPP, the national certification program administered by CARST alongside Health Canada, and not every monitor sold online carries it. Some have also been subject to recalls, so it is worth a look at the federal recalls database first. The comparison table below shows how the strongest options stack up. ## Quick Overview: Our Top Picks | Product | Best For | Why We Love It | Price | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------- | --------------------------------------------------------------------------------------------------------------- | ----------- | | ![Ecosense EB100 digital radon detector with plug-in design and clear display](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpc5d6n380.webp) **[Ecosense Digital Radon Detector](https://www.amazon.ca/dp/B0B64JBLS6?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Real-time home monitoring | Updates measurements every 10 minutes and works without a smartphone or subscription. | $165.00 CAD | | ![Airthings Corentium Home radon gas detector in grey, Canadian Bq/m³ version](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpmf7qgl3j.webp) **[Airthings Corentium Home](https://www.amazon.ca/dp/B00H30TLPA?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Portable battery monitoring | Battery-powered design offers straightforward Canadian Bq/m³ readings without requiring a permanent outlet. | $142.99 CAD | | ![X-Sense radon detector with digital display and audible and visual alerts](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmphi0yailt.webp) **[X-Sense Radon Detector](https://www.amazon.ca/dp/B0GGRS72TN?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Alerts and stored reports | Stores up to 99 reports over 999 days and switches between Bq/m³ and pCi/L at the touch of a key. | $76.99 CAD | | ![Airthings Wave Radon smart detector with humidity and temperature sensors](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpyibrqwd0.webp) **[Airthings Wave Radon](https://www.amazon.ca/dp/B07WWV7K3K?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Smart-home integration | Connects with Airthings devices, Google Assistant, and Alexa while monitoring radon, humidity, and temperature. | $179.99 CAD | | ![Aranet portable radon detector with E-Ink display and environmental sensors](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpbzcy8l1t.webp) **[Aranet Radon Detector](https://www.amazon.ca/dp/B0DK3CRP79?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Long battery life | Premium portable monitor combines 10-minute response, environmental readings, and a claimed seven-year battery. | $279.00 CAD | | ![Radonova Radtrak³ alpha track radon detector beside a smartphone showing the Radonova app](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/radonova-radtrak3-radon-test-kit.jpg) **[Radonova Radtrak³](https://www.amazon.ca/dp/B08G8VJYD2?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Long-term lab analysis | Sits in place for 90 days to a year, then returns an accredited lab result with postage and analysis included. | $132.00 CAD | | ![CRADTEC white digital radon detector with tempered glass display and Bq/m³ or pCi/L readings](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpdhsgjkm8.webp) **[CRADTEC PRM-03H](https://www.amazon.ca/dp/B0B23YYQPV?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Lowest-cost digital display | Switchable Bq/m³ and pCi/L readings, audible alerts, and year-plus battery life add everyday flexibility. | $75.99 CAD | ### [Ecosense Digital Radon Detector](https://www.amazon.ca/dp/B0B64JBLS6?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Ecosense EB100 digital radon detector with plug-in design and clear display](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpc5d6n380.webp) Monitor indoor radon levels with real-time updates and easy setup Ten-minute measurement updates make the [Ecosense EB100](https://www.amazon.ca/dp/B0B64JBLS6?tag=thecanadarepo-20&ref=thecanadareport.ca) a sensible mid-range choice for households that want a current radon reading without relying on a smartphone app or subscription. It plugs into a wall outlet for ongoing monitoring, which builds a fuller picture than a single one-time test. The simple digital unit uses an ionization sensor, includes an audible alarm, and supports both short- and long-term monitoring. At 6 x 7 x 7 cm and 0.34 kg, it is compact enough for a stable indoor placement away from drafts and direct heat; its listed upper temperature range is 40 °C. Priced at about $165 and rated 4.5 stars from 719 customer reviews, it costs a little more than basic display-only options but adds faster update intervals. #### Pros - Refreshes measurements every 10 minutes - No smartphone or subscription required - Audible alarm adds a clear warning feature #### Cons - Requires a nearby outlet for continuous operation - Costs more than a display-only digital monitor ### [Airthings Corentium Home](https://www.amazon.ca/dp/B00H30TLPA?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Airthings Corentium Home radon gas detector in grey, Canadian Bq/m³ version](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpmf7qgl3j.webp) Monitor indoor radon levels with the grey Airthings Corentium Home For homeowners who want ongoing radon readings instead of relying solely on a one-time kit, the [Airthings Corentium Home](https://www.amazon.ca/dp/B00H30TLPA?tag=thecanadarepo-20&ref=thecanadareport.ca) is our straightforward top pick. This Canadian version displays results in Bq/m³, so there is no need to convert units when considering Health Canada guidance or discussing results with a mitigation professional. At $142.99, it sits below the feature-heavy smart monitors while still giving you a dedicated display. Battery power means it does not need a permanent outlet, making it practical to position in the area you want to monitor. The grey unit measures 2.5 x 7 x 12.1 cm and weighs about 150 g, while its visual alarm provides an on-device warning. Keep it in a dry indoor location: its listed operating humidity is below 85%. Its 4.6-star rating from roughly 2,900 reviews supports its strong value-for-money case. #### Pros - Canadian Bq/m³ display avoids unit conversion - Battery-powered placement needs no permanent outlet - Compact 150 g unit is easy to relocate #### Cons - Operating humidity must remain below 85% - Visual alarm is less detailed than app-based alerts ### [X-Sense Radon Detector](https://www.amazon.ca/dp/B0GGRS72TN?tag=thecanadarepo-20&ref=thecanadareport.ca) ![X-Sense radon detector with digital display and audible and visual alerts](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmphi0yailt.webp) Monitor radon levels with X-Sense’s battery-powered detector At $76.99, the [X-Sense Radon Detector](https://www.amazon.ca/dp/B0GGRS72TN?tag=thecanadarepo-20&ref=thecanadareport.ca) is one of the least expensive ongoing monitors here, and it adds the record-keeping that makes fluctuating household readings easier to follow. It stores up to 99 local reports and is designed to monitor for up to 999 days, so budget-conscious households can build a longer picture rather than reacting to one short result. Double-tapping the peak key switches the display between Bq/m³ and pCi/L, so Canadian buyers can read results against Health Canada guidance without converting anything. Audible and visual alerts bring attention to readings without requiring an app, while the display also shows temperature and humidity ranges. Its 4.4-star rating from 703 customer reviews suggests solid buyer confidence for the price, and the stated two-year battery life keeps maintenance minimal. #### Pros - Stores up to 99 local monitoring reports - Switches between Bq/m³ and pCi/L readings - Audible and visual alerts add simple at-home awareness #### Cons - No app-connected tracking is listed - Two-year battery life is shorter than premium rivals ### [Airthings Wave Radon](https://www.amazon.ca/dp/B07WWV7K3K?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Airthings Wave Radon smart detector with humidity and temperature sensors](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpyibrqwd0.webp) Monitor radon, humidity, and temperature with the Airthings Wave Unlike the display-only picks in this guide, the [Airthings Wave Radon](https://www.amazon.ca/dp/B07WWV7K3K?tag=thecanadarepo-20&ref=thecanadareport.ca) is built for households that want radon readings alongside humidity and temperature data in a connected setup. It works with the free Airthings app, Airthings View devices and Hub, plus Google Assistant and Alexa. That makes it a sensible premium choice for tracking changes over time, rather than relying on one short reading. The battery-powered unit has a visual alarm and measures 11.9 by 11.9 cm, with a 3.6 cm depth; it weighs 218 g. At $179.99, it costs more than the guide’s straightforward top pick, but its 4.4-star rating from about 2,450 reviews supports its appeal for smart-home users. Keep it within its specified operating range: below 85% humidity and up to 40 °C. #### Pros - Tracks radon, humidity, and temperature together - Works with Alexa, Google Assistant, and Airthings devices - Battery-powered design avoids a nearby outlet #### Cons - Costs more than straightforward display-only monitors - App connectivity is central to its appeal ### [Aranet Radon Detector](https://www.amazon.ca/dp/B0DK3CRP79?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Aranet portable radon detector with E-Ink display and environmental sensors](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpbzcy8l1t.webp) Monitor radon levels, temperature, humidity, and pressure with Aranet A claimed seven-year battery is the headline feature of the [Aranet Radon Detector](https://www.amazon.ca/dp/B0DK3CRP79?tag=thecanadarepo-20&ref=thecanadareport.ca), a premium portable monitor intended to keep collecting readings without frequent battery changes. It reports radon in either Bq/m³—the Canadian-friendly setting for following Health Canada guidance—or pCi/L, while its E-Ink display also shows temperature, relative humidity and pressure. The listed 10-minute response time offers quicker visibility into changing home conditions, though radon decisions still need longer-term averages. At 7.7 x 7.1 x 7.1 cm and 218 g, it is compact enough to move between areas, with an upper temperature rating of 40 °C. The free app adds connected tracking, and its 4.7-star rating from 264 customers is encouraging. At $279, it is firmly a premium choice. #### Pros - Claimed seven-year battery reduces routine maintenance - Selectable Bq/m³ and pCi/L readings - Shows radon, temperature, humidity and pressure #### Cons - Costs much more than straightforward radon-only monitors - Short-term readings still need long-term interpretation ### [Radonova Radtrak³](https://www.amazon.ca/dp/B08G8VJYD2?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Radonova Radtrak³ alpha track radon detector beside a smartphone showing the Radonova app](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/radonova-radtrak3-radon-test-kit.jpg) Radonova Radtrak³ measures for 90 days to a year before lab analysis Health Canada advises measuring for a minimum of three months, and the [Radonova Radtrak³](https://www.amazon.ca/dp/B08G8VJYD2?tag=thecanadarepo-20&ref=thecanadareport.ca) is built for exactly that window. It is an alpha track detector: a small passive device that sits in place for 90 days up to a full year, after which you mail it back for analysis at an accredited laboratory. Registration takes a few minutes, and both return postage and the lab analysis are included in the $132 price, so there is no separate fee waiting at the end. Radonova runs radon testing in more than 50 countries, which is worth knowing given how many low-cost kits on the market route samples to U.S.-only labs. The detector itself is tiny at 6.4 x 6.4 x 2.5 cm and 80 g, and it is rated for indoor use only. Its 4.2-star rating comes from a smaller pool of 44 reviews than the established digital monitors here. The trade-off is straightforward: you get one carefully measured, lab-confirmed long-term average instead of a live number on a screen. #### Pros - Covers the 90-day minimum Health Canada recommends - Accredited lab analysis and return postage included in the price - Passive detector needs no batteries, power or app #### Cons - No live reading — results arrive after the exposure period - Fewer customer reviews than the established digital monitors ### [CRADTEC PRM-03H](https://www.amazon.ca/dp/B0B23YYQPV?tag=thecanadarepo-20&ref=thecanadareport.ca) ![CRADTEC white digital radon detector with tempered glass display and Bq/m³ or pCi/L readings](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/08/tmpdhsgjkm8.webp) CRADTEC radon detector with switchable units and long-lasting battery life At about $76, the [CRADTEC PRM-03H](https://www.amazon.ca/dp/B0B23YYQPV?tag=thecanadarepo-20&ref=thecanadareport.ca) is the lowest-cost dedicated display in this guide, and it still switches between Canadian Bq/m³ and U.S. pCi/L readings. Its tempered-glass, 300 DPI screen is intended to keep the numbers easy to check, while audible alerts can draw attention when readings call for a closer look. The detector runs on three AAA batteries, with a stated battery life of more than one year, so it suits a set-it-and-check-it approach to ongoing home monitoring. Its 4.3-star average from 451 ratings is encouraging, though it has fewer reviews than our top Airthings pick. Give any monitor time to build a meaningful longer-term picture before drawing conclusions. #### Pros - Switches between Bq/m³ and pCi/L readings - Audible alarm adds a useful warning feature - Three AAA batteries are stated to last over one year #### Cons - No app-connected history or remote tracking is listed - Fewer buyer ratings than established leading models ## Choosing a Radon Monitor That Gives You More Than a One-Time Snapshot A radon detector is most useful when it helps you understand exposure over weeks and months, not just one reading on a particular day. Levels can change with ventilation, weather patterns, foundation conditions and how a home is used, from tightly closed Prairie basements to older homes in Ontario, Quebec and Atlantic Canada. Start by deciding whether you need a simple screen in the basement, an app-connected record you can review over time, or a long-term kit that ends in a lab report. ## Continuous Radon Monitors vs Long-Term Test Kits: Which Canadian Homes Need? Continuous radon monitors provide repeated readings in the room you occupy, making them the better choice for understanding ongoing exposure rather than treating a single result as the full story. Our top pick, the Airthings Corentium Home, displays Canadian Bq/m³ readings and costs $142.99, a straightforward middle ground for households that want a dedicated display without an app. Place any monitor in a regularly used lowest level of the home, away from drafts, windows and direct heat, then pay attention to longer averages rather than reacting to a short spike. A long-term kit such as the Radonova Radtrak³, at $132, works differently: the detector sits undisturbed for 90 days to a year and then goes to an accredited lab, which lines up with Health Canada’s advice to measure over at least three months. That makes it a strong option for a home sale or a definitive first answer, though you wait for the result rather than watching a screen. A plug-in monitor needs an outlet, while battery models avoid that constraint. For a result near or above Health Canada guidance, continued monitoring and mitigation advice make more sense than repeating short tests alone. ## What Does Spending More on a Radon Detector Actually Buy You? The price spread is meaningful: these options run from $75.99 to $279\. Spending about $76 on the CRADTEC PRM-03H gets a screen with switchable Bq/m³ and pCi/L readings, while the X-Sense model at $76.99 adds audible and visual alerts, stored reports, and temperature and humidity displays. Those are sensible choices if a basic on-device reading is enough. At $132, the Radonova Radtrak³ buys accredited lab analysis rather than features, which is a different kind of value entirely. At $142.99, the Airthings Corentium Home remains the strongest straightforward value for most Canadian homes, supported by a 4.6-star rating from roughly 2,900 reviews and a Canadian Bq/m³ display. Paying $179.99 for the Airthings Wave Radon brings app tracking plus humidity and temperature sensors. At $279, the Aranet adds an E-Ink display, app access, pressure readings and a claimed seven-year battery, which suits buyers who value portability and long battery life. More money does not make short-term fluctuations more meaningful; adequate averaging time still matters. Warranty terms and battery replacement costs vary, so check them before paying extra. A display-only monitor is genuinely enough when the goal is clear, ongoing radon data without another app. ## Readings, Placement and Tracking Features That Matter in a Canadian Home ### Long-Term Averages, Not Just Fast Updates Fast updates can be reassuring, but they should not be mistaken for a final assessment of household exposure. The Ecosense EB100 updates measurements every 10 minutes and provides both short- and long-term monitoring, while the Aranet model also lists a 10-minute response time. Those quick figures show changing conditions, yet longer averages are more useful when deciding whether to contact a certified mitigation professional. Health Canada advises taking action when a long-term radon level is above 200 Bq/m³. Keep the monitor in its intended location long enough to see a meaningful trend rather than reacting to one unusually high or low day. ### Canadian Bq/m³ Readings and Sensible Interpretation Canadian shoppers should favour a monitor that displays becquerels per cubic metre, the unit used in Health Canada guidance. The Corentium Home’s Canadian version is the straightforward choice here. Several alternatives offer flexibility: the Aranet detector, the X-Sense and the CRADTEC PRM-03H can all switch between Bq/m³ and pCi/L, which may help when comparing information from U.S. sources. A consumer monitor is not automatically a Health Canada approved product. Devices are certified in Canada through C-NRPP, administered by CARST alongside Health Canada, and plenty of marketplace listings carry no certification at all. Check the federal recalls database before buying, especially if shopping through third-party sellers. ### Display-Only Simplicity or App-Based History A screen-only radon gas detector suits people who want to check the basement, main-floor living space or bedroom without setting up another account or wireless connection. The Corentium Home runs on batteries and uses a visual alarm, while the Ecosense EB100 plugs in and needs no smartphone. For more detailed records, the Airthings Wave Radon connects to the free Airthings app and works with selected View devices, Hub, Alexa and Google Assistant. The Aranet also pairs with a free app. App tracking is worthwhile for households documenting readings before or after mitigation, but it is not necessary for a dependable basic monitor. ### Placement, Power and Everyday Practicality Place a monitor in the lowest lived-in level of the home, away from windows, exterior doors, drafts, direct heat and high-humidity areas. A basement rec room used daily is generally more relevant than an unfinished storage corner. Battery models are easier to position without hunting for an outlet: the Corentium, X-Sense and Airthings Wave Radon all use battery power, and the passive Radtrak³ needs no power at all. The Aranet adds a claimed seven-year battery and a portable E-Ink display. For a fixed location near power, the corded Ecosense EB100 may be convenient. Do not move the device repeatedly; consistent placement makes long-term averages easier to interpret. ### Budget Versus Added Sensors and Alerts The CRADTEC PRM-03H is the cheapest way into a live display at $75.99, and the X-Sense model is barely more at $76.99 while adding audible and visual alerts, temperature and humidity display, up to 99 local reports and monitoring for up to 999 days. The Radonova Radtrak³ costs $132 and returns a lab-analyzed long-term average, though a passive kit alone cannot show how readings fluctuate day to day. Premium options add more environmental data: Airthings Wave Radon costs $179.99 and measures radon, humidity and temperature, while the Aranet reaches $279 with temperature, relative humidity and pressure. Buy extra sensors only if those readings will change how you manage the home. Radon is not the only invisible risk worth checking around a Canadian house — our [FireSmart guide to wildfire-proofing a BC home](https://www.thecanadareport.ca/firesmart-home-protection-canada/) covers the outdoor side of the same problem. ## Frequently Asked Questions ### Which radon monitor is the best choice for most Canadian homes? The Airthings Corentium Home, in its Canadian Bq/m³ version, is our top choice for most homes. It displays Bq/m³, the unit used in Health Canada guidance, and keeps operation simple with no app requirement. At $142.99, it costs a little more than a long-term lab kit but far less than feature-rich smart monitors near $279\. Its 4.6-star rating from about 2,900 reviews adds useful buyer confidence. ### Is a long-term test kit enough, or should I buy a monitor? A long-term kit can be a sensible starting point, especially if you are checking a home before a move or want one definitive result. The Radonova Radtrak³ fits that role: it sits in place for 90 days to a year, then goes to an accredited lab with postage and analysis included. A monitor is the better choice for understanding ongoing exposure, since radon can shift with ventilation, weather, renovations, and how the home is used. It also lets you see whether a single result reflects a lasting pattern. ### Where should I place a radon detector, and how long should I watch the readings? Place it on the lowest level of the home that is regularly occupied, such as a finished basement or main floor. Keep it away from windows, exterior doors, vents, direct sun, damp spots, and high-traffic areas. Don’t judge the home from one daily reading: radon naturally fluctuates. Watch the long-term average over months, then use Health Canada’s 200 Bq/m³ reference level when deciding whether to seek qualified mitigation advice. ### Should I choose a display-only monitor or an app-connected radon detector? Choose a display-only unit if you want to check the number in passing, avoid account setup, and keep the device simple for everyone in the household. The Ecosense EB100 is aimed at that straightforward approach. An app-connected option such as the Airthings Wave Radon makes more sense if you want historical graphs, phone notifications, and temperature or humidity context. The app is useful only if you will actually review the trend data. ### How much should Canadians spend on a radon detector? Expect a display-only digital monitor to start around $76, a long-term lab-analyzed kit to land near $132, and premium smart, multi-sensor models to reach about $279\. Spend more when ongoing records, alerts, or environmental sensors will help you act on the information. For many households, a mid-priced dedicated monitor is the practical value point: it avoids waiting on lab processing and provides repeat readings without paying for smart-home features that may go unused. ## Which Radon Detector Is the Right Fit for Your Canadian Home? For most Canadian homes, the [Airthings Corentium Home](https://www.amazon.ca/dp/B00H30TLPA?tag=thecanadarepo-20&ref=thecanadareport.ca) is the clear first choice. It keeps the job simple: ongoing radon readings on a dedicated display in Canadian Bq/m³, with no app or subscription to manage. At $142.99, its 4.6-star rating from roughly 2,900 reviews also makes it a particularly convincing value for a household that wants to move beyond a one-time test and watch its exposure over time. The better pick can change with your setup. Choose the [Ecosense EB100](https://www.amazon.ca/dp/B0B64JBLS6?tag=thecanadarepo-20&ref=thecanadareport.ca) if frequent display updates matter most; it is a plug-in monitor with 10-minute measurement updates and both short- and long-term tracking, priced at $165\. The [X-Sense Radon Detector](https://www.amazon.ca/dp/B0GGRS72TN?tag=thecanadarepo-20&ref=thecanadareport.ca) is worth considering for a lower-cost, battery-powered option with audible and visual alerts, local report storage, and temperature and humidity readings; it costs $76.99. If you would rather have one carefully measured answer than a live number, the [Radonova Radtrak³](https://www.amazon.ca/dp/B08G8VJYD2?tag=thecanadarepo-20&ref=thecanadareport.ca) at $132 covers the three-month minimum Health Canada recommends and comes back from an accredited lab. It cannot show you what is happening week to week, but it is the closest thing here to a definitive verdict on a home. Premium smart multi-sensor monitors can reach about $279, so only pay extra for app history and additional sensors if you will genuinely use them. Before buying, decide where the monitor will live: place it in the lowest regularly occupied level, away from drafts, windows, and direct heat. Let readings build over time rather than reacting to a single spike, and seek qualified mitigation advice if a sustained average approaches or exceeds Health Canada’s 200 Bq/m³ guideline. Pick a monitor, start recording, and give your home’s radon pattern time to reveal itself. ## Sign up for The Canada Report Your modern digest of Canadian news. Friendly, clear, and in your inbox.
