Every house contains some radon. Moreover, radon concentrations vary geographically and change at different times of the year.
Radon is present in every indoor environment, so it’s vital that homeowners must have their homes tested. Because long-term exposure to radon gas is harmful and can even lead to lung cancer.
Check out the Radon Potential Map of Canada Any home can have dangerous radon levels, regardless of geography.
Radon can seep into a home through soil, windows, cracks in foundation walls and floors, loose pipes fittings and support posts, floor drains and sump pumps, wall, floor joists, and even through your water facets! Concrete is porous, and radon is a gas. Therefore, that means it can penetrate through even the tiniest holes in a house.
There are three levels of radon reduction systems that builders can install into new construction.
Level 1 is a Rough-In for Active Soil Depressurization for Radon Reduction
Level 2- Full Passive Vertical Radon Stack
Level 3- Full Active Soil Depressurization
Level 1 is a Rough-In for Active Soil Depressurization for Radon Reduction. A radon-reduction system's entrance point for radon and other soil gasses is a pipe that extends into a soil gas collector (typically gravel) beneath the foundation floor. The pipe finally comes to an end and is covered just above the slab.
This system is merely a rough-in, and if radon mitigation is needed, a fan system can be added. In order to reduce radon ingress, a membrane has also been placed beneath the concrete slab and is sealed to the foundation wall. The majority of provinces and territories have followed this strategy, according to CARST.
Also, it is essential to caulk any foundation cracks and joints as well as the areas near the sump pit, floor drains, and other pipes.
Level 2 is an extension of Level 1, where the pipe from Level 1 is extended up through space vertically and out through a wall to terminate outdoors. Provisions must be taken to ensure the pipe is properly sealed to ensure re-entrainment of radon does not occur. The system relies on naturally occurring pressure differentials generated by the stack effect to mitigate radon. This level is now being used in the BC building code.
System Level 3 uses the pipe from Level 2 and also includes a low wattage radon fan. The system relies on the radon fan to induce a pressure difference to exhaust soil gasses and radon from under the slab. Radon fans run continuously, and a system pressure monitor is installed for the monitoring of the system. This method has been shown to be highly effective at reducing radon concentrations in a building.
Many different products are available that can be used in the installation process of a radon reduction system. Radon Guard and Radon Block are the best choices to prevent radon from the beginning.
Radon Guard® Insulation is a key component of any radon mitigation system. This code compliant replacement for code required 100mm layer of granular material under slab, is a 2 in 1 system that both insulates and protects interior spaces from radon gas for generations.
Radon Block® is the leading high performance radon blocking barrier membrane. It resists gas and moisture migration into the building envelope, providing superior protection from toxic and harmful chemicals. Evaluated as a code alternative solution CCMC 14024-R.

How Radon Block and Radon Guard work in an Active Soil Depressurization method
Radon is a radioactive gas created from the decay of uranium minerals present in rock, soil and water. You cannot see, taste or smell radon. Outdoors there is little danger as radon is diluted in the open air. Indoors, radon can be trapped and become concentrated in enclosed poorly ventilated spaces resulting in a significant increased health risk.
Radon is the leading environmental cause of lung cancer and the second-leading cause of lung cancer next to smoking. Radon-induced lung cancer is preventable, Health Canada’s take action guideline is 200bq/m3. If your home tests above this take action guideline, a mitigation system should be installed.
Check out the Radon Potential Map of Canada.
RADON MITIGATION is the process used to reduce radon gas concentrations in the home or in a building.
The radon test is a test to identify the level of radon in your home. A radon test can be done by a professional home inspector or by yourself using a radon test kit or the radon tester. Testing radon can be a DIY project. Besides, there is also radon testing equipment for inspectors.
A radon test identifies the radon level in your home so you can make an informed decision and take action if necessary. You can purchase a long-term radon detector and test yourself or hire a certified radon professional to test for you.
All homes have some amount of radon, the question is how much. Since you cannot see, taste or smell radon, scientific testing is needed for detection. Testing for radon is an important part of assessing your Indoor Air Quality and should be taken seriously to protect the health of everyone who enters your home. High levels of radon can lead to a significant risk of lung cancer.
Some radon stays in the water, drinking water containing radon also presents a risk of developing internal organ cancers, primarily stomach cancer. Radon is only a concern in your water if your drinking water comes from a well (groundwater). Water from wells can have high radon concentrations because radon is relatively insoluble in water.
Water use releases radon into the indoor air and contributes to the total indoor airborne radon concentrations. Radon can be off gassed in the shower, kitchen sink and through the laundry. Radon can be removed from our water using an aeration system, this can significantly reduce the level of radon in your water. The Airwell radon system lowers radon levels in well water up to 99%.
Solve the problem of radon in well water before water enters the home. Radon reductions up to 99%.

January 3, 2023 - The Bark Side of Radon, presented by Radon Environmental (REM), is a Canadian public awareness campaign promoting home-owner radon testing through pet health. Medical conditions that veterinarians see in animals are like those doctors see in patients, but the diseases often develop earlier in animals.
"The Company is pleased to announce that it is joining forces with Citizens for Radioactive Radon Reduction (CR3), in the United States, to expand the campaign to protect all our loved ones, from exposure to cancer causing radon gas, across North America" said Alan Whitehead, President & CEO of REM.
"Your pets are at the lowest level near the ground. Because of their silence, we can be less aware of their suffering until it's too late." says, Jackie Nixon, Cancer Survivor. "We found that the general public truly cares about their pets and really want the best for them. Talking to them about how radon affects animals and how they can protect their pets, really gets their attention and increases their willingness to consider testing for radon."
The oncologist said, “radon is a known cause of lung cancer”. When my husband, Joe, was diagnosed with lung cancer. A radon test revealed we had been living with over 4 times the EPA action level of this demon for 18 years and didn’t know it. We, like millions of others, didn’t know that radon exposure could cause lung cancer; and we didn’t know this silent killer was living with us." says Gloria Linnertz, CR3 President.

Can you run a ceiling fan during a radon test?
No. During the test, turn off any air-moving equipment. Ceiling fans, dehumidifiers, conventional fans, HEPA filters, and any other air-moving filtering equipment fall into this category. During the test, only use fireplaces or heating stoves if they are your primary source of heat.
Do dehumidifiers remove radon?
No, buying a dehumidifier will not make radon go away.
Does rain affect radon testing?
In short, yes, radon concentrations are predicted to be slightly higher within your home on rainy days. The weather is one of the most important factors in radon levels. Weather changes, especially severe weather, can modify pressure differences and, as a result, the way radon enters your home. Radon levels in a home typically rise after specific weather events, such as storms. Strong winds, for example, can cause radon levels to rise or fall. Depending on the situation, weather events can cause your radon levels to rise or decline. Weather has a number of effects on your test, and it's impossible to forecast which ones.
Do open windows affect radon testing?
It's vital to remember that while testing for radon, the house must be completely closed up – that’s why is it best to test in the fall and winter months. The test will be invalid if any outside doors or windows are open.
Does opening doors reduce radon?
Opening windows to minimise radon levels isn't a viable long-term strategy. Open windows, can minimise radon in the short term, allowing you to stay in your home safely until you can build a permanent solution.
Can air purifiers reduce radon?
Air cleaners or purifiers are machines that filter or electrostatically remove particulates from the air, such as dust or radon decay products. Air cleaners are routinely used to condition indoor air for several health benefits and overall comfort in the home, and attempts have been made to market air cleaners to prevent radon decay. Mold, dust, allergies, germs and viruses, and odours are all things that air purifiers can help with, but there are manufacturers that claim they may also aid with poisons, gases, and compounds like radon. An activated carbon filter is the most effective form of air filter and, according to some research, can help in reducing radon levels. However, this technology has not been proven to help decrease the health concerns associated with radon. The EPA does not recommend using air cleaners to reduce radon decay products in indoor air at this time. Although air cleaners will remove some radon decay products, numerous issues remain about the relative health effects of the decay products that aren't removed and the possible impacts of the radon decay products' undiminished source. The EPA feels there is insufficient evidence to recommend the installation of air cleaners to lower the risk of exposure to radon and its decay products until additional data is available.
Are portable radon detectors accurate?
There are definitely several reliable portable radon detectors. If fact, Ecosense EcoCube and Radon Eye are in the top 10 Radon Detection Devices by Best Review Guide for 2022.
Can radon cause mental illness?
For many people, radon does not directly cause psychological disorders. However, the potential of radon in your home can cause anxiety and restless thoughts about the prospective health risks of living in a home with a high radon level. New research is being conducted every day, and there are university studies looking into linking Radon exposure to early on-set Alzheimer’s.
Do Ceiling fans reduce radon?
Ceiling fans do not reduce radon. In fact, if the blades on the fan are pulling air upwards it could actually increase the radon levels very slightly.
Does every house have radon?
Every home has some radon, although concentration levels differ from one home to the next, even if they are near to each other. The only way to know how much is to test for Radon.
Extra care must be taken to seal around the pipe where it penetrates the Radon Block engineered membrane.
Active soil depressurization system using RN4EC4 Fan
There are many factors to consider when finding a radon mitigation system that is right for you. That’s why we advise that you consult with a radon mitigation specialist. They will test your home’s radon levels, address the size of your home and type of foundation, and take into consideration soil and weather characteristics, installation and system operation costs.
It's also important to consider the radon mitigation system effectiveness. For example, active suction systems reduce radon concentrations by 50% to 99%, while passive suction systems only lower concentration levels by 30% to 70%. A passive system, on the other hand, may be sufficient if your radon gas concentrations are on the low end of the scale. If radon levels rise, you can easily add a fan later.
Let’s review the factors you should consider when finding the best radon reduction system.
Radon is a naturally occurring radioactive gas that results from the breakdown of uranium in soil and rock. It is odourless, tasteless, and colourless. When radon is discharged into the air from the earth, it is diluted and is not a health hazard. It can, however, build up to dangerous amounts in enclosed environments such as dwellings.
Radon can enter a home through any fractures in foundation walls and floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sumps, or cavities inside walls where the house is in contact with the ground.

RELATED: RADON TESTING: WHAT RADON TEST DO YOU NEED?
Mike Holmes with a fully installed mitigation system in a home.
Depending on which radon mitigation system you choose to install in your home, you can lower radon levels by up to 99 percent.
Radon in the air is reduced through ventilation, which can be gathered beneath a concrete floor slab or through a ground membrane, or by increasing the number of air changes per hour in the building. Radon can be removed from home water sources using aeration or activated charcoal treatment devices.
Your contractor will evaluate numerous factors when choosing a radon reduction solution for your home, including:
Your home's radon level
Installation and system operation costs
The size of the house and the type of foundation
Soil characteristics and weather
The characteristics of your home determine the efficiency of any radon-reduction procedure by the amount of radon present, how it enters your home, and how effectively the work is done. While a single strategy may be effective, there are occasions when a combination of methods is required.
THE ONLY WAY TO KNOW IF YOU HAVE RADON IN YOUR HOME IS TO GET TESTED.
Spray foam alone is not a radon mitigation system and a radon fan and exhaust point are still required to constitute a complete mitigation system.
A tighter house will be more energy-efficient than a leaky house, allowing for higher radon gas concentrations. That's why it's crucial to retest for radon after a home has been air-sealed or new insulation has been installed. Spray foam insulation prevents radon from entering your basement by sealing gaps and cracks in the walls. Thus, decreasing the amount of radon entering your home will create healthier indoor air quality and help regulate the temperature in your home. Spray foam forms a continuous air barrier that protects against radon and other gases as the first line of protection. Spray foam also acts as a vapour barrier, protecting the foundation. However, spray foam alone is not a radon mitigation system and a radon fan and exhaust point are still required to constitute a complete mitigation system.
RADON AND VENTILATION
Installing a heat recovery ventilator system (HRV) is by far the most straightforward option for radon reduction. An HRV can be used in both new and existing homes, and it exhausts the radon-containing old air and replaces it with fresh outdoor air. HRVs provide a consistent level of airflow throughout the year if properly balanced and maintained and can also help to enhance the indoor air quality in homes with additional contaminants.
Coupled with an HRV, Radostat provides the simplest radon mitigation system that is highly beneficial for retrofit and new build scenarios
The NRC in Ottawa has published data relating to the effectiveness of the HRV as a radon mitigation tool. It is important to balance the HRV slightly positive, when using it as a radon mitigation system as the positive pressure helps stop the ingress of Radon into the home.
The Fantech Fresh Air Appliance can ventilate your entire home with fresh outdoor air up to 20 times per day while recovering 80% of the energy. The building codes in Alberta, British Columbia, Saskatchewan, Manitoba, New Brunswick, the Yukon, Nova Scotia, and some sections of Prince Edward Island all mandate radon rough-ins and it’s important to note that all new builds in Ontario require HRV installations.
Tip: You can add a device called a Radostat from Radon Environmental that will measure your Radon levels and pilot the HRV to run when Radon levels are high.
Clean outdoor air is drawn into the unit. The fresh air is warmed and distributed throughout the house. Stale, musty, humid, and impure air is extracted from the home and used to warm up the cold incoming air. The unhealthy warm air is then expelled to the outdoors. An innovative counterflow core exchanges energy while keeping airflow separate to avoid contamination.
Sealing any openings in your home where radon could enter could help lower your radon levels. However, it is not a stand-alone strategy for reducing radon levels because it is difficult to find, access, and securely seal all openings.
Other openings your radon mitigation professional will look at are:
Open Sumps: An airtight cover can be added to sumps. If the sump also serves as a floor drain, a unique trap should be added to the airtight cover, which should be slightly recessed into the sump.
Floor Drains: Special traps can be built in basement floor drains to allow water to drain while preventing radon from entering the basement. Molds, odours, insects, and cold draughts are all kept out by using these traps.
Floor Wall Joint: The seam between the foundation wall and the basement floor can be sealed if it is accessible. This joint can play a significant role in radon levels in a home.
Exposed Soils: A plastic membrane with sealed edges and seams can be used to cover exposed earth in crawl spaces. After a membrane has been built, concrete can be poured to cover any exposed soil in a basement that does not have a floor slab (e.g., a cold storage room).
Voids in Concrete Block Walls: Seal cavities in the top of the foundation and inner load-bearing walls if there isn't a solid row of block.
After shutting main openings, minor entry routes that are visible or accessible can occasionally be sealed to further reduce radon levels. Minor foundation cracks in the walls and flooring can be repaired. Larger cracks necessitate unique techniques; consult a contractor or a construction material supplier. The gap around utility penetrations in walls and floors (e.g., water, sewer, electricity, natural gas, fuel oil) can also be sealed using low expansion spray foam.
Water drainage systems inside a home can provide an easy pathway for radon to enter your home. However, when the sump pit is covered with a sealed lid and connected to a venting pipe, the amount of radon entering your home can effectively be reduced. You can also connect a radon mitigation system to it if you have an exterior drain located outside next to your foundation. The radon is drawn from the soil and through the sump to an outdoor exhaust point above the home's roof by a radon fan linked to the vent pipe.
Your radon mitigation system will typically come with a lifetime warranty when installed by a licensed provider, but it is always advised to be aware of the warranty upfront. The fan, however, is not covered by the system guarantee and a typical manufacturer warranty is 5-years, while other fans may have a shorter or longer warranty period. It's always best to work with your licensed provider and understand the maintenance and warranties associated with your specific system.
One of the biggest radon fan manufacturers is Fantech, and the Fantech RN2 Radon Fan is one of the top 5 radon fans on the market.
These are active soil depressurization systems that use a radon vent fan. These systems are made up of various parts: The radon suction pipes are placed in the basement or crawlspace and enter the earth beneath.
The exterior Radon Mitigation systems seen in the USA where the code is to have the pipe external to the house. In Canada, by contrast, the fan is installed in the house. The Fantech line of Fans meet both specifications. It is important that if you pass the pipe through the attic in unconditioned air that you insulate the Radon pipe as the air passing through it is very humid and the pipe can freeze in winter months.
The radon suction pipes are placed in the basement or crawlspace and enter the earth beneath. Radon gas and other soil gases from the ground are sucked into the suction pipes. The suction pipe continued up the foundation wall and into the garage, penetrating the rim joist.
A passive radon system is a radon system without a radon exhaust fan. A passive system typically runs from the basement sump crock or drain tile and exhausts through the roof without using an active radon exhaust fan.
Passive radon systems rely on a phenomenon known as the "stack effect." To carry air and radon gas through the pipe from the basement to the exhaust vent, the stack effect relies on air pressure differentials. When there is a difference in indoor and outside air density due to temperature and moisture fluctuations, air buoyancy occurs.
The stack effect is usually insufficient to considerably lower radon levels in a passive radon system because new dwellings are typically airtight to accommodate energy efficiency.
Extra care must be taken to seal around the pipe where it penetrates the Radon Block engineered membrane.
A radon mitigation system will comprise a long-lasting air and moisture barrier that will completely cover the dirt floor of the crawl space. Radon gas can be mitigated by encapsulating the crawl area. To make this procedure work, extra care must be taken to seal around the pipe where it penetrates the plastic sheet. When using this method, it is important to select the right membrane. We recommend Radon Block which is an engineered 20 mil membrane that has a very low radon diffusion coefficient and is very durable.
RADON REDUCTION SYSTEM IN NEW CONSTRUCTION
At a minimum, builders should have some rough-in that includes: a layer of clean gravel or aggregate beneath the slab or flooring system, covered by polyethylene sheeting, a gas-tight venting pipe from the gravel level through to the outside of the building or roof, and sealing and caulking all gaps and cracks in the foundation are all essential requirements.
Installation of Radon Guard in a new construction build with RDC Fine Homes.
An alternative to the clear gravel is Radon Guard, a structural sub slab insulation panel that will add R value below your slab and at the same time creates a 68% void space from which to vent Radon and soil gasses as well as drain the water. It is code approved to replace the clear gravel layer in both Canada and the USA.
Level 2 is a complete passive radon reduction system that employs a vertically stacked stack that exhausts above the roofline. Due to the stack effect, the technology reduces indoor radon levels sporadically and does not require electricity. Radon levels are typically reduced by 50% with a Level 2 system.

Signs of Radon Poisoning
Radon is a silent killer. According to the Lung Association of Canada, radon is the second biggest cause of lung cancer in non-smokers. While radon decays, radioactive particles develop, which can become trapped in your lung tissue as you breathe. The energy released by radon particles can harm the cells in your lungs. Lung cancer can develop when the cells in your lungs become damaged.
You are at an even higher risk of lung cancer if you smoke and reside in a home with a high level of radon.
Common Symptoms:
Shortness of breath.
A persistent cough.
Tightness or pain in the chest.
Hoarseness.
Trouble swallowing.
Radon is a gas that enters the body as small particles. When these particles penetrate the lungs, alpha radiation is released, harming lung cells and leading to lung cancer. Unfortunately, radon poisoning has no treatment. The effects of the radiation are irreversible.
Lung cancer takes at least five years to develop when a particle destroys a cell and causes it to become malignant, but it commonly takes 15 to 25 years or even more. Only a few people who are exposed to radon develop lung cancer, but the more you are exposed to it, the more likely you are to develop lung cancer.
Radon exposure occurs in every building. The only way to know how much you have is to test for it. After entering buildings through cracks and other openings in the foundation, radon gas becomes trapped inside. Indoor radon can be regulated and managed using tried-and-true methods.
The highest levels of radon are typically found in the basement or first floor, and levels can vary from house to house, even homes side-by-side!
A radon test determines the amount of radon present in your home. There are two types of testing: a do-it-yourself radon test kit or a test performed by a C-NRPP professional house inspector or radon specialist.
Mike Holmes Inspections inspectors are fully trained professionals certified by the Canadian National Radon Proficiency Program (Canadian-NRPP). C-NRPP professional house inspectors or radon specialists are specially trained to provide you with expertise and knowledge to help homeowners and building owners measure and reduce their radon levels.
To minimize radon, most people utilize a system that includes a vent pipe(s) and a fan(s). These "sub-slab depressurization" solutions don't necessitate any considerable housing modifications. Crawl space dwellings can also benefit from similar solutions. These systems keep radon gas from the house by trapping it beneath the concrete floor and outside the foundation. Radon mitigation contractors use other radon reduction methods that may work in your house. The best system is determined by your home's design and other considerations.

The week ended with the 8th Annual B.C. Radon Workshop in Abbotsford, BC hosted by the BC Lung Foundation. This year’s workshop had a record attendance of over 100 attendees, including many local realtors! The session was divided in the afternoon with a special session for realtors led by Dr. Noah Quastel from Simon Fraser University/British Columbia Lung Foundation. Workshop presenters included representatives from Health Canada, BC Centre for Disease Control, CAREX, C-NRPP, CARST, Interior Health, Fraser Valley Regional District, SFU, North Vancouver City Library and Radon Environmental.

There are no immediate symptoms to exposure to radon at low, moderate or high levels. Symptoms of illness as a result of radon poisoning include those of lung cancer or stomach cancers. If you are concerned about your health, contact your doctor or health official who is knowledgeable about the effects of radon.
Anytime is a good time to test. The best time is during the winter or heating season when doors and windows are closed. If you live in a home with a well, don’t forget to test your water also!
To provide a realistic estimate of the radon exposure of your family, all measurements should be made in the lowest lived-in level of the home. That means the lowest level that is used or occupied for more than four hours per day. For some, this may be a basement with a rec room, for others it will be the ground floor.
A short-term radon test is a screening test to get fast results. An example of this is to get an idea how much might be held in escrow for a real estate transaction. A long-term radon test is recommended in order to make a mitigation decision. Health Canada recommends conducting a long term test for a minimum of 3 months - this will provide an average radon concentration which can be compared to the threshold defined in the national guideline.
If your radon test result is above Health Canada’s guideline of 200 Bq/m3, a C-NRPP certified Mitigation Professional can help you identify the best radon mitigation system for your space. They will design an effective system, install it according to proper protocols and follow up with a test to ensure the system’s effectiveness in reducing radon levels immediately after installation. The good news is it’s fixable!
August 27, 2019 - Radon Environmental is launching The Bark Side of Radon, a radon awareness campaign encouraging pet owners to test their indoor air quality for radon. The Holmes family, including Mike Holmes Jr., Sherry, and their furry family members, are supporting the campaign with videos for pet lovers (see links below). The key message? Pets are part of the family and breathe the same air we do. Protecting their health is protecting your whole family’s health when you test for radon.
Radon, a radioactive, invisible gas, is the second leading cause of lung cancer. Seven times heavier than air, radon accumulates close to the ground – where your pets are. Animals can’t take action to protect the air they breathe, but you can.
The Bark Side team is reaching out to every homeowner that loves their pets. To bolster the campaign, they’ve brought on Bark Ambassadors like Simon Fraser University (SFU) professor Anne-Marie Nicol. The campaign started as a health risk communication project to raise public awareness of radon in Nicol’s Faculty of Health Sciences class. Radon Environmental President, Alan Whitehead recognized the idea’s potential to amplify radon awareness. “We love our pets like family – they are our family and best friends. Protect their health and wellness by preventing exposure to radon and the associated cancer risk. Pet owners who care are pet owners who test,” says Alan.
Emily Li, one of the SFU students behind the idea, is now working with Radon Environmental. The momentum has been building with outreach to the animal wellness community, including veterinary colleges and offices, animal advocacy groups, and pet food supply stores. “This is a unique approach to communicating a public health hazard,” explains Nicol. “By reaching out to pet owners known for their high level of commitment to their animal’s health, we are motivating them to test for radon and protect everyone in the home.”

Today is World Lung Cancer Day. Lung Cancer claims more lives worldwide than breast, prostate and colon cancer combined. Radon induced lung cancer is real and preventable. Like most people, Janet thought only people who smoked got lung cancer. But that’s not the case. Watch her story.
Rachael Malmberg was diagnosed with stage 4 lung cancer at age 31. The former national-level U.S. hockey player had never smoked and had lived a perfectly healthy life. Since her diagnosis, Malmberg has become an advocate for radon testing. Read more about Rachel's story.
Radon is the leading cause of lung cancer among nonsmokers, according to EPA estimates. Overall, radon is the second-leading cause of lung cancer (after smoking). Health Canada recently increased its estimate of radon induced lung cancer deaths to approximately 16% of all lung cancers or approximately 3,200 Canadians that die annually from radon exposure.
Health Canada's policy is that all Canadian homes should be tested for radon and mitigated if above the action guideline. Interestingly, many people do not choose to mitigate after finding their dwellings have elevated radon levels. Mitigation need not be difficult or costly.
The only way to know how much radon may be present in your indoor air is to test for it. You can order a radon test online to test your home - it’s easy and inexpensive!
