Growing up in southeast Wisconsin, I sometimes take our beautiful terrain of rolling hills and deep valleys for granted. A mere 25,000 years ago huge masses of glacial ice moved along our landscape moving earth, sand and stone, leaving us with the lakes, kettles and moraines we enjoy today. Unfortunately, that glacial movement also freed a silent foe…………..Radon. Many of the large stone formations that were moved and broken by the glaciers contained uranium. As that uranium decays in the soil radon gas is released.
To learn more about radon, I went to Bob Vescio, owner of Advanced Radon Management. Bob explained that radon is colorless and odorless gas that emerges up from the earth. Cracks in foundation floors, as well as, open sump wells allow these soil gases egress in homes, out buildings and commercial structures.
So how dangerous is this stuff? Well, for starters, “it’s the leading cause of lung cancer in non-smokers and recently has been linked to certain types of Leukemia” Vescio said. He also told me he personally knows of one case of lung cancer that developed in only eight months of exposure. Scarier still, over 75% of homes in southeast Wisconsin have radon levels exceeding minimum standards, meaning that 7 out of 10 homes would not pass a radon test.
So what’s the good news? Bob told me that a professional radon test is relatively inexpensive, $100.00 -$200.00, well worth the piece of mind. However, keep in mind that with soil conditions constantly changing, due to our climate, a structure that receives a passing level, may not pass two years later. Radon levels are measured by equipment that determines the radioactivity per liter of air. An acceptable level used to 4 but has since been lowered 2.7 by the World Health Organization. Vescio said. He also told me that the lowest he has seen in our area is 0.3 while he’s seen levels as high as 216!
So what do you do if your radon level is high? Well, more good news, a professionally installed radon mitigation system is again, relatively inexpensive, under $1500.00 in most cases and minimally invasive.
A simple explanation of how this system works is, it takes the gas from under the floor and exhausts it outside where it dissipates. Typically installed in the basement, the system takes only a small amount of room, is silent, and cost about $100.00 annually to run. If you’re considering a lower level remodel have a system included in the design, if your basement is already done the system can still be added with little or no modifications.
I asked Bob if structures built on slabs or those with shallow basements, like many tri-levels are at risk. He told me, these structures should be tested as well since radon may be present near the surface. He said, “You should be concerned anytime, you move, build or remodel, if a system isn’t in place”
In the end, it seemed plain as day to me that, any home, work shop or commercial structure in southeastern Wisconsin is at risk. It also seems prudent to just have the system installed since passing one test does not mean you’ll never be at risk. If you’re diligent in testing every two years, the system would pay for itself in 7 or 8 years anyway. Bob also told me that these systems help reduce window condensation, improve air quality, and reduce dampness. Today it’s pretty common knowledge that many ailments are the result of poor indoor air quality, installing a radon mitigation system is an important part of improving your homes environment.

So very many people out there have no idea how dangerous it can be, just as cancerous as smoking a pack a day.
Thanks for the posting. Very informative.

What are the odds, one in one hundred gazillion?
Sounds like a scare tactic to me.
" An acceptable level used to 4 but has since been lowered 2.7 by the World Health Organization."
The EPA recommends mitigation if the level exceeds 4. For non-smokers, the risk of cancer from radon exposure of levels between 2-4 compares to the risk of dying from poison.
Why did you remove my last post?
Is it because I'm challenging your assertions?

Next, your reference to EPA standards is correct and quite easy to substantiate on the web, however my reference was to the standard set by WHO (World Health Organization). With another relatively simple search on the web one can ascertain the a much longer and highly controlled study was done globally to arrive at their number of 2.7. Sorry, I’m going with the big one!
The spirit of the post was to create awareness of potential health hazards related to elevated levels of radon gas, not to scare anyone. When we purchased our house 10 years ago we had to have basement work done to stop water intrusion, while referencing the condition report our basement company rep found a radon test report in the file stating that we had a radon level exceeding 11! Ignorant to the ramifications, I discounted his concern. A few years later, I met Bob Vescio and listened to him explain the health risks of radon and researched it some on my own after which, I immediately contracted him to install a system. In my opinion, any radon is to much for my family. So for what it’s worth, that’s my story and I’m sticking to it.
Thanks for the comments

I'm a little confused by the reference you make to a condition report. I know that when purchasing a home the seller is required to furnish a real estate condition report to the buyer. If the seller was aware of high radon levels in the home and didn't list that as a defect on the report, the seller may be held liable for misrepresentation.

Uranium is abundant in our soil, therefore radon is too. Even if a condition report does not state that there are high levels of radiation at a home, that's not to say they will not go up in a few years. Take a look at Wisconsin's Radon levels throughout the decades. You will see that they have increased tremendously. Since Wisconsin is a farming state, soil is constantly being turned, matted, and turned up again. Since the half-life of Uranium is about 4.5 billion years, it is easy to see Radon is unavoidable and needs to be a cause of concern. I'm not saying that it is a reason to panic, but the chances of knowing someone with radon-related lung cancer is less than one in one hundred gazillion (And yes, I did take high school math, and passed). Actually I do believe that 20,000 or so deaths are related to Radon each year in the United States. Consider the blog a reminder that radon is present, and can be harmful, rather than a way to judge Bob's remarks. I mean you can stick with the scare-tactic theory but then again, it's better to be safe than sorry.

I can't believe I have actually witnessed this: a person who is Pro-Radon. Anyone who owns a home in SE Wisconsin has at least a passing knowledge of the prevalence of Radon in the soil, and sometimes, even in groundwater. In addition, if you are aware of Radon, you are likely aware of the health risks it poses, even if you don't know the specifics.
So instead of reacting to the information in the article as a rational, logical adult, you use an ad hominem attack, and a ridiculous reference to a non-existent number.
If you knew anything about the development of cancer, you would know that there is no set standard for susceptibility to a particular form of cancer among all humans (as in a "1-in-x chance"), rather, each person has a varying degree of susceptibility to developing a particular form of cancer. This individual susceptibility is based on factors such as genetics, lifestyle and environment. For example, one person may never develop lung cancer in a particular home, yet another may develop it quite rapidly. You may have also heard in recent years about the discovery of a "breast cancer gene" which greatly increases the risk of a woman who carries this gene developing breast cancer at some point in her life.
It would seem the wise choice in issues about health would be to inform oneself about the risks (if you view predominately terminal diseases such as lung cancer to be a bad thing, as I do, and something you would not want to develop), and take appropriate action to avoid or mitigate those risks, to the extent that your personal economics and behavior allow. Which really was the point of the article.

Bernee mentions that there are 20,000 radon related deaths per year in the U.S. Given the current population of 304 million, 1 in 15.2 million will die due to radon exposure this year. Oh, the humanity!
Sorry folks, I just don't find that to be an especially alarming statistic. The odds of dying as a result of being uninsured are greater.
Unless you work outdoors, you're spending approx. a third of your day in a structure that may have high levels of radon. Does anyone ever give that a moment of thought? And what about the schools? "EPA estimates that more than seventy thousand (70,000) schoolrooms in use today have high short-term radon levels."

Are you putting your children at risk?

The radon mitigation guy knows of someone who died after only eight months of exposure. I don't know about anyone else, but that's enough to set off my bs detector.
For those who may be interested, you can purchase an EPA approved do-it-yourself radon test from your local hardware store for under forty dollars...it's so simple a cave man can do it. There, I've added informational value to this blog. My good deed for the day.
Concerning your next blog, you'll be happy to know that "at this time EPA believes that the existing data is insufficient to conclude that the types of granite commonly used in countertops are significantly increasing indoor radon levels." :-)

You're a blast! Stay with us, I enjoy your sense of humor. The Lone Ranger had Tonto, Matt Dillon had Festus, Colonel Sanders had .....um, ok bad example, but I've got Jmark.
