Radon gas is probably the last thing on your mind when you think about your home. After all, it's not something you can see, smell or taste, so it's easy to forget that it's even there. But radon gas is a real threat to your family's health, and it's important to take the necessary steps to mitigate it.
As the leading cause of lung cancer among non-smokers, radon gas is estimated to cause about 21,000 deaths each year in the United States. That's why it's so important to protect you and your family by having a radon gas mitigation system in place, in your home.
But with so many different types of mitigation systems on the market, it can be tough to know which one is right for your home.
Here's a quick guide to the best radon gas mitigation systems for your home, so you can keep your family safe from this invisible threat.
What Is a Radon Gas Mitigation System?
By now, you've probably realized how big of a threat radon gas can be and that a radon gas mitigation system is a must in any home. But what, exactly, is a radon gas mitigation system?
A radon gas mitigation system is designed to remove radon gas from your home and keep it at safe levels. Technically it won't remove the radon from your indoor. Technically it extracts the radon from the ground, which results in a significant decrease in indoor radon concentrations since radon comes from the ground.
There are a few different types of systems, but they all work to achieve the same goal: reduce the amount of radon gas in your home. There are different types of systems because there are different methods one can use to mitigate radon.
Radon gas mitigation systems work by either drawing air from your home and venting it outside, sealing radon out from your home, or by extracting the radon from the source, AKA the ground. This process helps to keep the levels of radon gas in your home at a safe level, so you and your family can breathe easy.
The Best Radon Gas Mitigation Systems for Your Home
Now that you know a little bit more about radon gas mitigation systems, let's take a look at the best ones for your home.
Active Sub-slab Depressurization (ASSD)
Active sub-slab depressurization is one of the most effective radon gas mitigation systems on the market. Also known as sub-slab depressurization, this system works by drawing air from beneath your home's foundation and venting it to the outside.
This system is most effective in homes with a poured concrete foundation. Even if the basement is completely finished, ASSD will still work effectively.
One or multiple suction pipes are installed in the basement after coring a hole through the concrete slab. They are then connected to a radon fan that draws air from beneath the foundation before venting to the outside. This process helps to keep the levels of radon gas in your home at a safe level.
ASSD systems are extremely effective - the most effective type of system that exists currently. Regarding the cost, when comparing it to a furnace or HRV, it is significantly cheaper.
Passive Sub-Slab Depressurization (PSD)
Passive sub-slab depressurization is similar to ASSD, but doesn't require a vent fan. Instead, this system relies on the natural pressure differential between the indoor and outdoor air to draw air from beneath the foundation and vent it to the outside.
PSSD systems are associated with radon-resistant construction techniques, which are designed to prevent radon gas from entering your home in the first place. These construction techniques can be used in new construction settings or during a home renovation.
PSSD systems are effective, though not as effective as ASSD systems. They're also less expensive to install and require very little to no maintenance.
Soil suction is a type of radon gas mitigation system that's typically used in homes with crawlspaces. This system works by drawing air from the crawlspace and venting it outside.
One or multiple suction pipes are installed in the crawlspace and are connected to a radon vent fan that draws air from the crawlspace and vents it to the outside. This process helps to keep the levels of radon gas in your home at a safe level.
Soil suction systems have proven to be very effective at reducing radon levels in homes, especially when they are combined with a membrane sealed overtop of the soil and/or rock. They can be trickier to install compared to an ASSD system.
Block Wall Suction
Block wall suction is similar to soil suction, but it's typically used in homes with block walls instead of crawlspaces. This system works by drawing air from the spaces between the block wall and the foundation and venting it to the outside.
Basement homes that have hollow block foundation walls can benefit from this type of system. By utilizing a fan and ductwork, this system draws air from the block walls and then vents the radon gas to the outside, helping to keep the concentration levels of radon gas in your home below the guideline.
Heat Recovery Ventilation (HRV)
Older homes that don't have good ventilation can benefit from a heat recovery ventilation (HRV) system. This type of system helps to improve the air quality in your home by drawing fresh air in from outside while simultaneously exhausting stale indoor air to the outside.
HRV systems are typically used in homes that are built so air tight that they require a mechanical means of ventilation. These systems are also used as solutions in homes that have other indoor air quality issues, such as mold or radon.
As mentioned earlier, HRV systems work by drawing fresh air from the outside and exhausting stale, indoor air. The fresh air is drawn through a heat exchanger, which helps to cool or heat the air before it enters your home. This process helps to not only improve the air quality in your home, but it can also help to reduce your energy bills.
No one wants to be exposed to radon gas, but unfortunately it's presence in homes is a concern worth addressing.
Luckily, there are a variety of effective radon gas mitigation systems that can help to keep your family safe. The 5 systems described above are some of the most popular and effective systems on the market.

Radon: Your Chance To Know
Chance to know what?
Your chance to find out just how much radioactive gas is lurking inside your home. Because no matter where you live, radon gas will live there too. There is no way to be 100% free of it.
So the question becomes... "Okay, well then how much of it am I living with in my house?"
And maybe a second question would be... "Well how much of this radioactive gas can I handle before it starts to harm me?"
Before we answer those questions however, we first need to tell you about Susan and Ashley - two middle aged, married women with families.
You see both of them have something in common. Something unfortunate for them, but an eye opener for everyone else.
A tragedy for these two individuals and their families, yet a new revelation and appreciation for those who learned from it.
These two otherwise healthy individuals with no bad habits, like smoking for example, were diagnosed with lung cancer. It grew and spread throughout their whole body. The battle was long and rough, but the cancer was too strong and they both passed away as a result.
The coincidence you see, was that each one lived in a house (2 very different houses), which both got tested for radon following their passing. It was revealed that, at the time, both houses contained incredibly high radon concentrations - over 10,000 Bq/m3 or roughly 271 pCi/L.
Again, they were otherwise healthy people who didn't smoke a day in their lives, but yet they died because a radioactive gas, that we cannot see, touch, hear or feel, gave them aggressive cancer.
So if you don't know what radon is or if you have never heard of it before, this is your chance to learn more about it. Our DIY Radon Test Kit includes information about where radon gas comes from, what you can do to protect yourself from its harmful effects and much, much more.
No one is exempt or invincible when it comes to radon, but...
At least we have the right tools and equipment available to us that can measure radon gas.
And the right equipment to mitigate the risk associated with radon right down to a point where it becomes no concern to our health.
So if you measure the amount of radon in your home and it's discovered that you have less than favorable results, it's okay. We can provide you with the resources, knowledge, references, and contacts necessary for you to tackle your radon issue and eliminate its risk permanently.
That's right, permanently! Never again will you have to address radon concerns after that. Unless of course you move to a different location.

Knowledge coupled with taking action is true power.
So seize the power. This is your chance. Order a radon test kit today. You will be happy you did.
Radon gas is a silent killer - one of those things that can be in your home or office, but you may not know about it until it does the damage. The affects can be very severe - according to various health authorities, radon is the biggest cause of lung cancer among non-smokers.
If you have recently built or moved into any building, it's imperative to check for radon. To do that, you'll need a radon test kit.
This article discusses what radon test kits are, when they are used and how to use them.
A radon test kit is a device used to measure the amount of radon gas in the indoor air. You set it up, allow it to detect radon gas for a predetermined amount of time, and then mail it to a certified lab capable of analyzing it. The lab will conduct a test and return the results to you via mail or email.
If you do a short-term radon measurement and detect high levels, it's recommended you do a long-term measurement afterwards to confirm. If you get the same/similar results the second time, it's time to take action.
Why Do You Need to Test for Radon?
The World Health Organization identifies radon as a carcinogenic agent that can cause lung cancer. About 25,000 and 3,000 people die from radon annually in the United States and Canada respectively.
While harmful, radon has no flavor, odor, or color; therefore, you'll need to do a special test to detect the presence of this gas.
Now remember, radon has been found in every part of the world and can build up in any building, anywhere. So, radon testing is something you can't afford to miss, for your family's safety.
Types of Radon Test Kit
There are two types of radon testing kits. Let's explore them.
A short-term test will take anywhere between 2 and 90 days. The type of short-term radon test kit we provide takes at least 10 days. It's mostly used as a screening test to determine if a long-term measurement is required; however, sometimes people cannot wait 90 days to receive a final test result. For example, realtors have a timeline to follow and are often pressured to get a list of tasks done before the closing date. They absolutely cannot wait 90+ days to receive results, so they depend on the results that come from performing a short-term radon test.
A long-term test kit measures the radon levels in an area for at least 90 days and up to a year. It is more accurate than a short-term test because it exposed to a greater sample size of radon gas; therefore, organizations like Health Canada, for example, only recognize the results derived from a test like this. On the other hand, the E.P.A. will recognize both short-term and long-term results.
Which Kit Should I Use?
Well, you should first conduct a short-term test to get a rough idea about the radon levels in your house. If the concentration is really high, then you should install a radon reduction system right away. If the short-term test results are just under or just above the guideline, then it would be a good idea to then perform a long-term radon measurement. You can also conduct a radon measurement - either short-term or long-term - after a radon mitigation system has been installed in your house so that you know it is working effectively.
Can I Do My Radon Testing?
Of course you can conduct a radon test on your own. You do not have to be licensed or certified to do so; however, since there are many steps and possibilities of committing an error, you may better be off calling a radon measurement professional if you want to make sure it's done right.
Also, depending on where you live, you may need to hire a professional to do radon testing for real estate transactions. Be careful about this - look into this prior to the start of any test.
How To Conduct a Radon Test
This depends on the type of kit you have bought. You'll need to look at the user's guide and follow the instructions accordingly.
Most testing kits consist of a radon detector, a form, instructions, some literature on radon, and return mailing packaging to ship off the sample. You place the detector in the basement and leave it for a minimum of 48 hours or longer, depending on the type of test.
Finally, you send the sample to the lab and get the results. You will receive the results by mail, email, or both.
Where Can I Get a Radon Test Kit?
Radon testing kits can be purchased from local hospitals and stores. If you live in the USA, you can buy them from your state's national radon program services website. Some tests require additional testing fees to be paid before the kits are mailed to the lab.
In addition, you can buy discounted test kits from our website for more convenience. We deliver everywhere in the USA, Canada, and soon to be all over the world.
Ways To Make A Radon Test More Effective
Here are some steps you can follow to get a more accurate reading of your home's radon level, especially if you plan on doing a short-term radon test:
More FAQs Related to Radon Test Kits
Here are some more frequently asked questions about radon test kits...
Are Radon Test Kits and Monitors the Same?
No, test kits are not the same as continuous radon monitors.
Continuous monitoring devices are more expensive and are generally used by professionals (although consumers are free to use them as well) to test the average radon level in the house. While accurate, they may be a luxury you don't need.
What Is a Passive Radon Detector?
You may often hear the phrase 'passive radon detector' when looking for a test kit. Don't be confused. It's just another name given to a detector in a radon testing kit that doesn't use electricity.
What to Do if I Find Radon Gas in My House?
The Environmental Protection Agency and Health Canada recommend installing a radon reduction system if you discover a high concentration of radon in your home. A high concentration would be considered any concentration above the guideline you choose to follow.
Where Does Radon Gas Come From?
Studies show that nearly 1 out of every 15 houses in the US and 6.9 % of houses in Canada have elevated radon levels.
This radioactive gas is fairly common worldwide, with 56 nations already responding to the W.H.O. radon survey.
Many people know that radon causes lung cancer but don’t know its source. If that’s the case for you as well, this article sheds light on everything you need to know about the origin of radon gas, including what it is, where it comes from, how it causes cancer, and other related FAQs.
What Is Radon Gas?
Radon is a radioactive gas produced by the decay of uranium, thorium, or radium in soil, rocks, and underground water. As you can see, all the particles that can create radon are naturally occurring and can be found everywhere in the world, making this gas very common.
Radon doesn't have any particular taste, feel, or smell. You'll need to do a special test to find its concentration in your home or office. Furthermore, radon can also exist outdoors, even if the concentrations aren’t as high as inside a building.
How Does Radon Get Into Our Homes?
Radon can enter buildings in two ways:
By Rising From the Soil
The air pressure inside a building is lower than in the soil, making air and gas move from high pressure to low pressure. In other words, the vacuum in the house sucks the gas from the soil when created, allowing it to enter from small cracks in the foundation. Other places from where radon can get into buildings include hollow block walls, dirt floors, sump pumps opening in floor drains, and openings in pipes, sewers, and other utility connections.
Via Well Water
Houses that use well water are susceptible to radon. This gas can mix in the water and be released into the air while showering or dishwashing.
You may also sometimes end up ingesting radon if you drink water from the tap. However, it's not a big concern in itself.
But again, the implications aren't in your favor - if the drinking water in your home has radon, there's a high probability that the air has it too.
Note: Drinking water with radon can cause stomach cancer in some rare cases, but the risk isn't as much as cancer in the lungs caused by radon gas in the air.
Does Radon Exist in Every Building?
Yes, almost every residential or commercial building has radon gas; however, not all of them have high radon concentrations. While there is no safe quantity for radon, according to the WHO, levels of less than 2.7 PCI /l (100 Bq/m3) can be considered normal. If the radon concentration is higher, you should take action to mitigate your risk.
Why Are Radon Levels Higher Indoors Than Outdoors?
With its massive volume, outdoor air dilutes radon gas down to a concentration that is negligible. Furthermore, with passing time, more and more radon can accumulate inside a building, increasing the danger. When outdoor air is introduced to the indoors, this fresh air will dilute the indoor radon concentration.
What Makes Radon Cause Lung Cancer?
Radon is considered the second leading cause of lung cancer and the biggest cause of the disease in non-smokers.
As we discussed earlier, it is a radioactive gas. This gas releases tiny alpha particles into the air, which can collect in your lungs when inhaled. These particles eventually release tiny bursts of energy, slowly damaging your lung tissue and increasing your risk of developing lung cancer.
Does Radon Cause Other Types of Cancer?
Based on existing evidence, lung cancer is the only disease that can be caused by inhaling radon.
Rarely, radon can cause stomach cancer when ingested. This phenomenon is similar to what happens in the lungs - consumed radon can diffuse into radioactive particles that can stick to, and damage the stomach linings, eventually causing cancer.
Please note that more research is needed on this topic because some studies associating radon and stomach cancer have mixed results.
What Types of Houses Are More Likely to Have the Radon Problem?
Honestly, there is no one common answer to this question.
Generally, homes with slab-on-grade foundations and crawl spaces are more likely to have radon since they have many openings that allow the gas to enter. Furthermore, the risks of radon exposure can be high for people that use their basement as a living space.
But again, the radon levels in the indoor air can depend on many other conditions and variables, like the presence of radioactive materials in the soil, building materials, etc. And remember, even neighboring houses can have very different radon levels.
Hence, it's difficult to generalize, and every homeowner should be wary of radon. Every individual house/unit/dwelling needs to have a test done to determine it's risk level associated with radon.
How Can I Know the Radon Level in My House?
You can use either one of these amazing radon test kits to find the amount of this radioactive substance in your house.
These kits provide you with a hockey puck looking device to be placed in the basement or a room you use often.
Depending on the type of the type of kit you use, you will wait between 2 and 90 days or between 90 days and a year before sending the detector to the lab for analysis.
On the other hand, you can also contact a professional radon technician for radon testing. They will be able to give you more accurate readings faster, but usually at a greater cost.
What Can I Do About the Elevated Radon Levels in My House?
The most common radon-reducing strategy requires the assistance of a radon mitigation specialist. The specialist will install a radon mitigation system consisting of fans, pipe and accessories to vent the radon away from the home, into the outdoor atmosphere.
Depending on the situation, the specialist will need to match the right strategy with the right circumstances. Some of these mitigation strategies include: aeration, GAC, sub-slab suction, sump-hole suction, or block-wall suction.
Radon is produced by the radioactive decay of uranium in the soil and can migrate upwards towards the surface. It can make its way inside your home through cracks, holes, gaps, penetrations, crawlspaces and others.
No matter where you're located in the world, when moving into a new house, you must test for radon regularly to keep your family safe from lung cancer.
Finally, you should contact a radon mitigation specialist if the levels are close to or higher than the recommendations given by your national health authority.
What is a Safe Radon Level?
Radon's presence in homes is a matter of great concern because long-term exposure to high radon gas concentrations can lead to an increased lung cancer risk. The U.S. Environmental Protection Agency (EPA) recommends that all homes be tested for radon and that corrective action be taken if necessary to reduce exposure.
So what is a safe radon level? While there is no known "safe" level of radon, the EPA has set an action level of 4 picocuries per liter (pCi/L) of air. This is the level at which the EPA recommends taking corrective action to reduce exposure.
For all of our Canadian readers, 4pCi/L is equivalent to 148 Bq/m2.
There are a number of ways to reduce radon levels in your home, and the type of corrective action you take will depend on the level of radon present and the type of home you have.
Here's a closer look at radon levels and what you can do to reduce your exposure.
Safe Radon Level: At a Glance
As we mentioned earlier, there is no set "safe" level of radon. However, the EPA has set an action level of 4 pCi/L, which is the level at which they recommend taking action to reduce radon levels.
The EPA's action level is based on the fact that if you are exposed to radon at this level over a long period of time, your risk of developing lung cancer is about 1 in 10,000. This might not seem very high, but it's important to remember that lung cancer is a very serious and deadly disease.
So, while there is no "safe" level of radon, the EPA's action level is a good guideline to follow. If your home has elevated radon levels (above 4.0 pci l), you should take steps to reduce it.
How To Check Your Home's Radon Level
If you're concerned about radon in your home, the best way to find out if you have a problem is to test for it. Radon testing is simple and easy to do, and it's the only way to know for sure if you have a radon problem.
There are two types of radon tests: short-term tests and long-term tests.
Short-Term Radon Tests
Short-term radon tests are typically used to test for radon over a period of 2-90 days. These tests are the most common type of radon test, and they're relatively inexpensive.
Short-term tests can be done with either electronic monitors or charcoal canisters.
Electronic monitors measure radon continuously and can be set to take readings over a period of days, weeks, or even months. On the other hand, charcoal canisters are placed in your home for a set period of time (usually 2-90 days) and then sent to a lab for analysis.
If you use a short-term test, it's important to remember that radon levels can fluctuate from day to day and even from hour to hour. So, a single short-term test might not give you an accurate picture of your home's overall radon level.
For this reason, we recommend using a short-term test first, followed by a long-term test if the results of the short-term test are 4 pCi/L or higher.
Long-Term Radon Tests
Long-term radon tests are used to test for radon over a period of more than 90 days. These tests are more accurate than short-term tests in terms of measuring your home's overall radon level.
If you're thinking of buying a home, it's important to have a long-term radon test done before making the purchase. This will give you an accurate picture of the level of radon in the home and whether it needs to be mitigated.
Long-term radon tests are typically done with either electronic monitors or alpha track detectors.
Electronic monitors, as we mentioned earlier, measure radon continuously and can be set to take readings over a period of months or even years. Alpha track detectors, on the other hand, are placed in the home for a set period of time (usually 90 days) and then sent to a lab to be analyzed.
Both types of long-term radon tests are considered equally reliable. The main difference is that electronic monitors tend to be more expensive than alpha track detectors.
What is the Average Indoor Radon Level?
The average indoor radon level in the United States is about 1.3 pCi/L. However, this number can vary significantly from home to home.
In general, homes in the Midwest and Northeast have higher radon levels than homes in the South and West. This is because of the geological conditions in these regions.
In some areas of the country, such as Colorado, Minnesota, and North Dakota, the average indoor radon level is closer to 3 pCi/L. In these states, it's estimated that 1 in 3 homes has a radon level above 4 pCi/L.
If you live in an area with a high average indoor radon level, it's especially important to test your home for radon and take steps to reduce it if necessary.
What Are the Health Risks of Radon?
Breathing in air that contains radon can damage the lining of your lungs and lead to lung cancer. In fact, radon is the second leading cause of lung cancer in the United States, behind smoking.
Smokers who are exposed to radon have an even greater risk of developing lung cancer. This is because smoking damages the lungs and makes them more susceptible to the effects of radon.
It's important to remember that radon is a radioactive gas, so it can't be seen, smelled, or tasted. The only way to know if your home has a radon problem is to test for it.
If you're thinking of buying a home, we recommend having a radon test done before making the purchase. This will give you an accurate picture of the level of radon in the home and whether it needs to be mitigated.
If you're already living in a home with elevated levels of radon, don't panic.
There are things you can do to reduce the level of radon in your home and protect your health. These include:
While there isn't an official "safe" level of radon, the EPA recommends taking action to reduce your exposure if your home has a radon level of 4 pCi/L or higher. So, if your house has a radon level lower than that, you're probably in the clear.
Of course, the best way to know for sure is to test your home for radon and take action to reduce it if necessary. This will help protect your health and the health of your family.
When it comes to keeping your family safe from radon, there is no such thing as being too cautious. This colorless, odorless, and radioactive gas can seep into your home through cracks in the foundation or other openings, and long-term exposure can lead to lung cancer.
According to the EPA, radon is the leading cause of lung cancer in nonsmokers, resulting in about 21,000 deaths yearly.
There is no safe level of radon exposure, so it's important to test your home regularly and take steps to mitigate the risk if elevated levels are found.
So, how do you go about testing for radon? There are a few different ways, but the most common is with a radon test kit. These kits are relatively inexpensive and easy to use, making them an excellent option for most people.
In this article, we'll take a look at five of the best radon test kits on the market. Let's dive in!
