World Lung Cancer Day - Because It Matters!

For all the flack the EPA can get, they do provide important health and safety information for the American public. Radon is one of those issues they have brought to the forefront and today it's important to remember the danger of radon and lung cancer - the #1 cause of lung cancer among non-smokers! 

At ResCom Radon Solutions we view community education and radon awareness to be an important part of our mission.  We know of families who have received the devastating news that a healthy family member has suddenly been diagnosed with lung cancer  - and they had never smoked nor had been exposed to second hand smoke.

As this article from the EPA points out:

"Lung cancer continues to be one of the most common cancers worldwide, accounting for nearly one in four deaths from cancer each year. The U.S. Environmental Protection Agency’s (EPA) Indoor Environments Division is focused on two important causes of lung cancer that may be present in indoor air: radon and secondhand smoke.
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). Radon is responsible for about 21,000 lung cancer deaths in the United States every year, and approximately 2,900 of these deaths occur among people who have never smoked. The only way to know how much radon may be present in your indoor air is to test for it.

The third-leading cause of lung cancer is secondhand smoke, which is estimated to be responsible for more than 7,300 lung cancer deaths among nonsmokers in the United States every year. Exposure to secondhand smoke also can have serious consequences for the health of children, including the triggering of asthma attacks."

Most people are not aware that radon exposure is the leading cause of lung cancer in non-smokers.  It's not just a statistic when 21,000 people in the US lose their lives needlessly to radon-induced lung cancer every year.  All it takes is to do a simple test for radon in your home, school, or workplace.  If unsafe levels are found, radon can be very easily mitigated through a radon mitigation system.  Check out our website for more information on how a radon mitigation system is installed.  www.RadonKC.com

Passive Radon Systems vs. Active What's the Difference?

By Tom and Georgiann Manz, ResCom Radon Solutions www.RadonKC.com

Seeing new homes springing up in the Kansas City area is a great thing.  That means more people are going to work each day and families are enjoying new neighborhoods in their new homes. 
In an effort to reduce the serious health risk of high radon levels in homes in the Kansas City area, more homes are being built with “passive radon systems.”  This is a good thing , however, we are finding that these passive systems are being labeled a "radon mitigation system" and home buyers being made to think there is no need to test for radon.  NOT SO!  And here's why:

1.       Builders frequently are not properly installing passive radon systems.

2.      A passive radon system does not function like an "active" radon mitigation system.

What is a “passive radon system?”
For the purpose of definition, a “passive” radon system relies on natural pressure differentials and air currents instead of a fan (used with active radon mitigation systems) to draw radon up from below the home.

According to the EPA, radon resistant construction should include:

-Installing a layer of clean gravel or aggregate beneath the slab or flooring system
-Laying polyethylene sheeting on top of the gravel layer

-Including a gas-tight venting pipe from the gravel level through the building to the roof (a passive radon system)
-Sealing and caulking the foundation thoroughly

 The radon-resistant construction components and a passive radon system help reduce the effect of soil gas pressure under the home.  If installed properly, the passive system helps air and soil gasses from beneath the basement floor flow up through the pipe to vent safely to the outdoors.

HOWEVER, studies are showing a passive radon system may very likely not have enough natural air flow to eliminate radon gas to the safest levels – especially if the passive radon system has not been installed correctly. 
If radon levels are still proven to be unsafe in a home with a passive radon system, a fan can be installed on the existing pipe in the attic to pull the radon gas from under the basement floor into the vent pipe where it can be exhausted outside the house. The addition of a fan and its associated wiring creates an "active" radon system. 

Even though passive radon systems are a good first step in new home construction, there are potential unseen problems that may exist – issues that the builders, buyers, or their realtors may not be able to recognize.

Builders typically use their plumbing contractors to install passive radon system vent piping from below the basement floor extending up through the framing, through the attic and out the roof.  Since most plumbers do not have specific training in radon system design and operation, they often make critical mistakes that limit or completely negate the purpose and effectiveness of the passive radon system.
Passive radon system design flaws include:

1.      The installation of the sub-slab suction pipe is not properly connected to the gravel bed.

2.      Although 3 inch vent pipe may be used in the basement, it is often reduced to a 2 inch pipe at the main floor level in order to pass more easily through the 2x4 house framing  This size reduction eliminates the possibility of using a radon fan for an active system due to the fan’s minimum 3 inch pipe requirement. 

3.      Vent piping in the attic is frequently installed up through or close to an outer wall not leaving a minimum of 18 inches of clear space in the attic between the ceiling joists and roof rafters.  This prohibits installing a radon fan in that location using the existing roof penetration. 

4.      Horizontal vent pipe runs are often not graded properly to allow condensation to drain through the vent piping back to the sub-slab gravel bed.  This becomes evident when the system is activated with a fan and water builds up in the pipe creating a sloshing sound which is annoying to the home owner, reduces the air flow of the radon system, and shortens the life of the fan.
Good news – bad news

Many builders in the KC area are installing passive radon systems as a part of their new construction process – the good news.  The bad news - many new home buyers (and builders, realtors, and home inspectors) assume that because a house has a passive radon system, they don’t need to be concerned about radon levels and, as a result, do not conduct a life-saving radon test during the home inspection process.
Since 40-50% of the homes tested for radon in the Kansas City area have levels above the EPA’s action level of 4.0 pCi/L (picocuries per liter of air), radon testing for all homes should be a major concern for residents.

What is the solution?

1.       First and foremost, every home should be tested for radon during the home inspection process!

2.       Builders, realtors and buyers need to be aware that having a passive radon system DOES NOT mean a home is radon safe. 

3.      If unsafe levels of radon are found in a home with a passive system, a certified radon contractor should be called in to examine the existing passive system and install a radon fan in the attic to activate the system.

4.       Certified radon contractors should be consulted in the passive design process and in the activation process. 

The issue of radon in homes, schools, and work places is a serious health issue.  Radon awareness is improving among realtors, builders, and the general population, but we still have a long way to go when you consider over 20,000 people each year needlessly lose their lives to radon-induced lung cancer.
How tragic that lives are lost from inhaling a natural-occurring gas that can be easily discovered by a simple air test and eliminated by an inexpensive radon mitigation system.  As radon awareness increases through proper information from builders, realtors, and home inspectors, radon deaths will lower and hopefully, one day, be a thing of the past.

The Fab Five - Top Need-To-Know Radon Facts

What you know and maybe don't know about radon will impact the health 
of you and your family.  We are finding that since we started ResCom 
Radon Solutions in 2009, a lot more information is known to the general 
population in the Kansas City Metro area and more and more residents 
are wanting to know if their homes, schools, and work places have an 
unsafe level of radon.

This is important because in the Kansas City area, 1 out of every 3-4 
homes has an unsafe level of radon.  That is quite significant.  And we 
are finding homes - even new homes with very high levels of radon.

We recently provided radon testing and mitigation for a health-related 
business in Cameron, Missouri, that was finishing their lower level to be
a day care center for their employees' children.  What a thoughtful 

We tested for radon and found on the main floor a reading of  6.5 pCi/L 
and a reading of 11 pCi/L in the basement where the children and 
workers would be.  

While there is no "safe" level of radon, the EPA has set their "action" 
level to be below 4.0 meaning radon mitigation should be done at any
 level 4.0 and above.  But the employees and children that will be 
spending their days at this health facility will be radon safe thanks to 
an informed and concerned employer.

So here are our Fab Five, need-to-know facts to help you be radon 

1.  The reality of radon and the danger of inhaling high levels of radon 
in a home, school, or building is a well-known, scientific fact.

Over 21,000 people each year die from radon-induced lung cancer as it is 
the leading cause of lung cancer among non-smokers - a Class A Carcinogen 
recognized by the Surgeon General, American Cancer Society, and the 
American Lung Association in addition to the EPA.

But the danger of radon is so easy to ignore since it is a long-term exposure 
issue, and that it cannot be seen, smelled, or tasted - a very dangerous 
"hidden health threat."

2.  Radon is EVERYWHERE and comes from the breakdown of uranium 
deposits in the soil and rock and can be emitted from well water. 

Radon enters buildings through cracks and other openings in the foundation 
and since it is "radio active," can even pass through concrete.

Although radon can be detected outdoors, it becomes dangerous when 
trapped inside a building and becomes more concentrated -  especially 
in today's tighter "energy-efficient" homes.

3.  Living in a home with a radon level of 4 pCi/L is like smoking 8-10 cigarettes per day.

It is a long-term exposure risk like smoking; however, the impact of radon is believed to affect children more readily than adults.  You can read some of the testimonies of people who have fought radon-induced lung cancer who wish they had been more aware of the danger of radon at this website, http://www.cansar.org.

4.  High radon levels are found in all types of homes - old or new, walk-out basements or below ground level; crawl space foundations and slab homes.

48% of homes in Johnson County, KS are found to have high radon levels and 42% of homes in Jackson County, MO!   We find homes all over the Kansas City area with above-average radon levels but one of our most memorable mitigations was done on a brand new home in east Independence that tested at 62!  That is an example of what radon levels can be in the KC Metro.

5.  "A passive radon system" now being installed by some builders in newer homes is NOT an active radon mitigation system and very likely does not insure safe radon levels.   

Unfortunately, some builders and realtors are telling clients that a home with a "passive radon system" has taken care of the potential of high radon.  Not necessarily so!

A passive radon system installed in some new homes is simply a gravity air flow pipe from the sub-slab gravel up to the attic and venting through the roof.  It should also include a physical barrier of polyethylene laid down between the soil and house foundation.

But a passive radon system does not work like an active system with a fan that is continually pulling air from beneath the slab of a home and are found to only reduce radon 30%-40%.  Passive systems can be "activated" by installing a radon fan on the pipe in the attic. Only a radon test will determine whether or not a home has safe levels.

There you have it!  That is our Fab Five Facts.

A Radon Problem in Your Real Estate Transaction?

We're hearing from realtors all over the metro area that they can't get homes listed quickly enough to meet the demand of eager buyers.  So if you are selling a home these days, that part of the process is moving along quite well in most cases.  However, gone are the days of simply selling a home and moving out.  New regulations and requirements take extra attention, time, and money to process through.  Home buyers and sellers have to rely on the professional services of their realtors, home inspectors, and other home services to work with them through this sometimes complicated process.

Certified radon professionals are one of those services being called upon to assist in the buying/selling process as many home purchasers have become aware of the potentially life-threatening danger of radon gas and are requesting radon testing during the inspection process - a very wise choice!  

Homeowners, on the other hand, oftentimes shudder to see a radon testing unit brought into their home.  "What's that?"  "I never heard of radon."  Recently a homeowner was so disturbed her home was being tested for radon in the sale process, she angrily phoned us with her questions about it and then abruptly hung up on me!

We understand that home sellers as well as purchasers get frustrated so we try to patiently answer their questions and make the process as painless as possible.  But the bottom line is, if unsafe levels of radon are found in a home after testing (the EPA "action level" being 4.0 pCi/L of air), buyers are going to want radon mitigation - and rightly so.  

It has been proven that radon is a radio-active carcinogen and causes lung cancer.  Radon is the leading cause of lung cancer deaths among non-smokers in the United States taking the lives of 21,000 people each year.  High levels of radon are frequently found in homes and buildings in the KC metro area.  The counties in the Kansas City area have been designated as "Zone 1" by the EPA meaning unsafe radon levels are found in 1 out of 4 or 5 homes.  Even moderate levels of radon are as damaging as smoking a half pack of cigarettes a day!

While great strides have been made in public awareness of radon, there is still a long way to go.  If everyone was aware of the danger of radon, every home, workplace and school would be tested and, if needed, mitigated.  The best part of that scenario would be that deaths caused by radon would virtually disappear!

So radon is a serious health issue but fortunately, there is a simple solution!  There is a cost, yes.  But that cost is one of the most economical you may ever have to make to improve the quality of your home.

One of the most frequently asked questions we get in a home sale about radon is, "Can high levels of radon really be fixed?  Can I purchase this home and know that my family will be safe?"

Finding out the home you want to purchase has high radon levels can be scary.  We assure home sellers, buyers, and realtors that a high radon level does not and should not derail a sale or make a home unsafe to purchase.

A realtor called us just this past week concerned about a high radon level (37 pCi/L) that was discovered during testing in a home she was helping her client purchase.  The home inspector had written in his report after doing the radon test and seeing these levels that he was concerned this high a radon level could not be mitigated!  A misinformed statement such as that CAN derail a sale - so unnecessarily!

Fortunately she called us, a certified radon professional, and asked the question, "Is that true?"  We were able to explain that that home, any home, can and will be safely mitigated and be radon safe.  And a post-mitigation test will confirm the radon levels have been lowered well below the EPA action level.

Even homes in the 50-60 range of radon levels have been very simply mitigated with a standard exterior system that we frequently install in homes with levels in the 4-10 range.  

So if you are a home buyer, do not shy away from a home that has unsafe levels of radon.  Request mitigation and a post-mitigation test to confirm radon levels are safe.  If you just move on to another home, possibilities are, in the KC area, the next home could have a higher level!   But there is no need to have a real estate sale fall through because of a radon problem.  Radon is an easy and relatively inexpensive fix.  

Radon mitigation systems work and can be installed in just a few hours.  Once the system is up and running, radon levels are usually reduced within 24 hours, the home is re-tested so safe radon levels are verified, and the sale transaction can move forward.

A high radon level may seem like bad news, but it's not all bad!  The good news?  The radon level can be fixed and the home sale can be completed.  More good news is that as homes are tested for radon through the sale and inspection process and mitigated, fewer people are being exposed to dangerous levels of radon gas. 

If you have questions about radon testing or mitigation, please give us a call at ResCom Radon Solutions.  We would be glad to talk with you.  You can also find out a lot of about radon testing and mitigation and view some informative videos at our web site,  www.RadonKC.com.

Tis the Season - To Be Radon Aware!

It’s amazing to think we are so soon entering the winter season and the holidays will soon be here!  We have had our furnace checked and are making other winter preparations at our house including checking our radon mitigation system.  This is especially important as we enter cold-weather months.
Now radon is no respecter of seasons - it is always "present."  (Pun intended!)  However, in the winter months when heating systems are being used in homes and buildings, radon levels increase.  It's called the "stack effect" or chimney effect. 

The winter season brings a higher radon levels for two reasons:

1. While a heating system is being used, warm air rises to the highest level of your home seeking a way to leave the home through attic vents. As heat rises, so does radon called the “stack effect” or chimney effect. As this warm air rises, it creates a vacuum bringing in air from any source in the lower areas of a home – in many cases the cracks and joints in a foundation.
We are not aware of this air exchange that is going on – nor are we aware of the radon gas that may be entering our homes as air is being drawn in from under and around a foundation. That’s why radon is known as a “silent killer” because it cannot be seen, smelled, or tasted.
2. The second reason radon tends to be at higher levels in homes in the winter is because of “closed house conditions.” During times windows are open, fresh outdoor  air can dilute radon levels.  In winter months just the opposite is true.  We try to keep our homes as protected from the winter cold as we can so we keep our homes as tightly closed as possible.

Caution!  If you have had your home tested for radon, and the level was around the action level of 4 pCi/L - either just under or just over, and you didn't have a mitigation system installed because it was "low," it could easily be a higher level in the winter months.  The EPA action level is actually considerably above the World Health Action level of 2.8.
Most of us are not concerned about the quality of air around us - we assume, unless we sense a funky odor, that the air is clean and safe.  But unless you test for radon's presence, you and your family could be inhaling the silent killer.
January is National Radon Action Month, designated by the EPA and other radon awareness organizations. When homes are tested, the radon danger is exposed and can be easily mediated or removed and families are guaranteed safety from this potential life-threatening danger
We didn't know we had dangerous levels of radon in our relatively new home 11 years ago.  We saw a story on a local news station about a Kansas City area man who had his office in his basement.  He didn't know he was inhaling dangerous levels of radon.  After some physical symptoms appeared, he went to a doctor and was shocked to find that he had radon-induced lung caner.  He lost his life within months.
This was a revealing and disturbing story since we had never even heard of radon back in 2006.  We ordered a free radon test from the state of Missouri and discovered that we, too, had dangerous levels of radon.  We immediately had our home mitigated and are thankful that danger has been eliminated. 
In 2009 we started our radon testing and mitigation business, ResCom Radon Solutions.  Since then we have installed over 1200 mitigation systems in the Kansas city area as well as testing thousands of homes, schools, apartment complexes, and commercial buildings. We are certified through the American Association of Radon Scientists and Technologists, carry environmental protection insurance, and operate our business with the highest level of integrity and attention to detail.
Give us a call to schedule a radon test or to receive a free radon mitigation estimate -and get a bunch more radon information by visiting our web site at www.RadonKC.com.  It’s important that you and your family be protected from potentially high levels of radon gas in your home – whatever the season.
And we wish you and your loved ones a blessed and safe holiday!

Where NOT to test for radon - it's important to know this!

The radon business has been quite active lately.  Homes of all types are being sold all over the KC Metro area at rates we have not seen in a decade. Thankfully, more home buyers are aware of the danger of radon and are having their new home purchase tested for this dangerous gas as part of the home inspection process.

Many homes we are testing are being found with exceptionally high levels of radon - a number of homes recently above 50 pCi/L.  The EPA "action" level is 4.0 so these are very dangerous levels and a reminder of how important it is to test homes, schools, and businesses for radon.

Something else we are finding are homes where home inspectors have tested for radon in locations within the home that do not meet EPA protocols - especially older homes with cellar-type basements.  What this means for home buyers and sellers is that the radon tests are not accurately reflecting the radon level perhaps leading to unnecessary mitigation installations or home buyers being scared off making the purchase.

Why is this happening?  Perhaps there has been inadequate radon testing education and training, but whatever the reason, home owners, buyers, and realtors need to have the right information about where to test and where not to test for radon.

EPA protocols state that the LOWEST POSSIBLE, LIVABLE SPACE, of the house should be tested for radon.

Here are some guidelines to help you navigate through the inspection process in reference to radon -


  • Cellar-type basements where adequate access (i.e. outside cellar doors) and/or low head clearance does not create a livable environment

    If you have to enter a basement area through an outdoor cellar-type entrance, it's most likely that is the type of basement area that will never be finished as a living room or bedroom.

    If a basement area has a head clearance that you can barely stand up in, that is not a "livable" space.

    Those are areas that need NOT be tested for radon according to EPA protocols.

    Houses without livable basements should be tested on the main floor in the central portion of the house such as the inside wall of a living room.
  • Crawl spaces

    Crawl spaces will never become a "livable" area.  The living area above a crawl space is where a radon test should be conducted.
  • Near sump pumps

    Areas close to an unsealed sump pump will cause elevated levels of radon which may not reflect the average radon level in the basement.
  • Laundry rooms, bathrooms, kitchen

    Areas like these create high humidity which affects radon tests.
  • On/near granite counter tops

    Granite counter tops do not usually produce dangerous levels of radon for occupants, but if a radon test unit is placed directly on the granite, the test can be elevated. 

So, where TO test?
  • In the unfinished or finished basement that could be, or is, a livable space
  • In a home without a basement, test in a main floor living area.

It is important to keep in mind that radon levels on the main floor living area in a home that has tested high in radon in the basement level, will have radon levels 40% - 50% of the levels found in the basement.

Correctly testing for radon can greatly affect the outcome of your real estate inspection.  Make sure your home inspector is certified in radon measurement or contact a certified radon contractor like ResCom Radon Solutions.

The EPA has publications to help home buyers and sellers learn more about radon and how important it is for every home to be tested for radon.  If radon levels are 4.0 or higher, mitigation is recommended.

Contact Tom Manz at ResCom Radon Solutions, 816-804-1791, for more valuable radon testing and mitigation information or visit our website at www.RadonKC.com.  We will be glad to answer questions, provide solutions, and help your home be radon safe!

2017 Radon Action Month!

Never has there been a topic that needs more exposure and public awareness than that of deadly radon gas.  The lack of knowledge of the dangers of radon gas in homes, schools, and businesses is responsible for over 21,000 lung cancer deaths a year - needless loss of life because radon-induced lung cancer is completely avoidable and could be eliminated if every home, school, and business would be tested for the presence of unsafe levels of radon.

Testing for radon is so simple and inexpensive - even free in the state of Missouri!  The Missouri Health Department office in Jefferson City offers homeowners a free radon test kit.  Just go to this link and they'll send it to you free of charge.  You simply return the test according to the directions and they send you the results.


As radon professionals, nearly every week we encounter a disgruntled customer who is selling a property that the buyer has requested be tested for radon as a part of the inspection process.  The seller is often one who has never heard of radon (and doesn't want to know about it), or has heard of it and doesn't believe it (head in the sand).

Many times the disbelieving seller seems to blame the radon professional for the problem of radon!  You can say you don't believe in gravity, but the evidence says gravity exists!  The same is true with radon.  No, it can't be seen, smelled, or tasted, but its effects can kill and its reality is without question.

In an effort to raise awareness and eliminate the lack of knowledge about radon, the EPA has designated the month of January as National Radon Action Month. 

Smoking is the number one cause of lung cancer deaths - 160,000 per year  - also mostly preventable but it is still a free country and people can gamble with their health if they choose to do so.  Second hand smoke causes an estimated 3,000 deaths a year.  But radon, much misunderstood and maligned, causes 21,000 deaths per year.

By the 1990's, enough evidence had been gathered by medical and scientific experts to determine that radon was a serious health hazard and the EPA established a radon department to not only lay down guidelines for radon testing and mitigation, but to promote radon awareness.  The American Lung Association, American Cancer Society, and individual state agencies are very actively promoting radon awareness.

Web MD has a good overview of the danger of radon at http://www.webmd.com/lung-cancer/tc/radon-topic-overview

The simple conclusion is that radon is a very real health hazard.  We can choose to ignore the risk and put our families' lives in danger; or we can take the logical choice to simply TEST - FIX - SAVE LIVES!

At ResCom Radon Solutions, we hope that you will make the informed choice for your family!  We are available to make a presentation about radon to any community group that would like more information.  We hope to be able to do our part to see the threat of radon outa here!
