Learn About Radon 
40% of all homes in Minnesota have a dangerous level of Radon.  4pCi/L is considered a dangerous level, and just 1 pCi/L is the equivalent to smoking 2.5 cigarettes a day.
If you or your family spends time in your basement your chances of being affected increase due to the fact that radon is nine times heavier than air.  Also toddlers that are crawling or children have a higher chance of being affected.
Minnesota winters also increase the exposure rate due to houses being sealed tight and furnace and water heaters running thus pulling the house into a negative pressure.
Give us a call if you have any questions 612-250-6645 . A radon mitigation system is not always needed. Our staff is highly trained on indoor air quality and also trained on different building techniques to determine the proper course of action to ensure you a safe house.

What is Radon ?
Radon is a cancer-causing radioactive, inert gas. You cannot see, smell or taste radon, but it may be a problem in your home. The Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today.

Where does Radon gas come from?
Radon is produced from the natural decay of uranium that is found in nearly all soils. The uranium breaks down to radium as it disintegrates, it turns into a radioactive gas. As a gas, radon moves up through the soil and into the air you breathe. Particularly underground work areas such as mines and buildings, are exposed to elevated concentrations of radon. Exhalation of radon from ordinary rock, soils and radon-rich water can cause significant radon concentrations in tunnels, power stations, caves, and so on. The average radon concentrations in houses are generally much lower than underground work areas.

How does Radon enter your home?
Radon gas moves up through the dirt and rocks into the air we breathe. The two components that affect how much radon will accumulate in a home are pathways it takes and air pressure.
      (Pathways are routes the gas uses to enter your home and is found in an opening between the home & the soil. Air Pressure between your homes interior and the exterior soil is what helps draw radon into your home via these pathways)

  • Basements: Radon can enter through cracks in the concrete or grooves manually made on concrete to help control where the concrete should crack, or through floor-to-wall joints.
  • Slab-on-Grade: Slabs built on grade and can have openings that allow radon to enter.
  • Crawl Spaces: Homes with crawl spaces can also have elevated radon levels
  • Manufactured Homes: Unless placed on supports without skirting around them, interior air pressure vacuums can cause radon to enter.
  • Minnesota homes operate under what is called negative air pressure; this means the air pressure inside your home is typically lower than the surrounding air and soil, especially during the heating season. This creates a vacuum that pulls soil gases into the pathways of the home. In general whenever air enters a home from the underlying soil, some radon will likely come with it.

Should you test for radon?
Since there are no immediate symptoms that will alert you to the presence of radon, testing is the only way to know your radon levels. It typically takes years of exposure before any health problems surface. Minnesota Department of Health recommends that all homeowners test for radon. We do one test prior and one test after the system is installed to determine the short term and long term averages to verify that the system is working correctly.
The short-term test measures radon levels for 2-7days; a minimum of 48 hours is required.
The long-term test determines the average concentration for a minimum of 90 days; this is the best way to estimate the average amount of radon in your home throughout the year. This radon test only provides the results for the period covered during the measurement

Test Results:
The actual radon levels in the home may vary depending on many factors including time, temperature, season, barometric pressure, ventilation, and other factors.
       A test result of less than 4.0 pCi/L “picocuries per liter” is below the present maximum recommended levels by the state and US Federal authorities. The Minnesota Department of Health & EPA recommends that you should “fix your home” if the radon level is equal to or greater than 4 pCi/L.
EPA & Minnesota Department of Health , recommends retesting every couple of years regardless of whether there is a mitigation system or not, and if you make any structural changes, as it can create new pathways for radon to enter your home.

What is a safe level of radon gas?  
The “safe” level of radon gas is no radon gas. The US EPA has put it plainly, stating, "Any radon exposure has some risk of causing lung cancer. The lower the radon levels in your home, the lower your family's risk of lung cancer." The average person receives a higher dose of radiation from the radon levels in their home than from their combined exposure to all other radiation sources, natural or man-made. The national average of outside radon levels are 0.4 pCi/L and it is estimated by the National Academy of Sciences that outdoor radon levels cause approximately 800 of the 21,000 radon induced lung cancer deaths in the US each year. Lung cancer risk rises 16% per every 2.7 pCi/L increase in radon exposure. (World Health Organization, 2009) Studies show that radon is the primary cause of lung cancer among people who have never smoked.   

                    The Radon Act 51 (The Health Physics Society, University of Michigan) passed by Congress set the natural outdoor level of radon gas (0.4 pCi/L) as the “target” radon level for indoor radon levels. Unfortunately, two-thirds of all homes exceed this level. The US EPA was tasked with setting practical guidelines and recommendations for the nation. To this end, the US EPA has set an action level of 4 pCi/L. At or above this level of radon, the EPA recommends you take corrective measures to reduce your exposure to radon gas. This does not imply that a level below 4.0 pCi/L is considered acceptable. As stated in the (BEIR VI) study, it is estimated that a reduction of radon levels to below 2 pCi/L nationwide would likely reduce the yearly lung cancer deaths attributed to radon by 50%. However, even with an action level of 2.0 pCi/L, the cancer risk presented by radon gas is still hundreds of times greater than the risks allowed for carcinogens in our food and water.

You've found radon in your home - what should you do?
Don't panic!  Radon is everywhere and fixing a radon problem is very straight-forward. Radon Mitigation is any process or system used to reduce radon concentrations in the breathing zones of occupied buildings. The goal is to reduce the indoor radon levels to below the World Health Organization action level of 2.7 pCi/L
