    How Do I Check For Radon?

    Conduct radon testing in the lowest lived-in level of your home. Tests should be placed in a room that is regularly used. Avoid testing in bathrooms or kitchens because moisture can affect the accuracy of tests.

    If you are considering selling your home, test for radon as soon as possible to avoid the time constraints of the real estate transaction process. 

    Step 1. Take a short-term test (2 to 90 days long). If your result is 4 pCi/L or higher take a follow-up test

    Step 2. Conduct a follow-up test with either a long-term test (90 days to one year) or a second short-term test.

    Step 3. If you followed up with a long-term test: consider fixing your home if the result is 4 pCi/L or higher. If you followed up with a second short-term test: consider fixing if the average of your first and second tests is 4 pCi/L or higher.

     

    How Dangerous is Radon?

    • Next to smoking, radon is the second leading cause of lung cancer

     The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States, second only to smoking. The U.S. EPA has established an "action level"  of 4 pCi/L (4 pico curies per liter of air). If your home has a radon level of 4pCi / L or greater EPA recommends that you fix the home. The average indoor radon level is estimated to be 1.3 pCi / L , 0.4 pCi / L is normally found in the outside air. Remember the ONLY way to know if you have a problem is to test. The EPA  recommends that you hire a state certified company that is trained to test and remove high levels of radon. For more information please go to our links page.

     


    How Does Radon Enter the Home?

    • Radon entry into buildings

      Radon moving through soil pore spaces and rock fractures near the surface of the earth usually escapes into the atmosphere. Where a house is present, however, soil air often flows toward its foundation for three reasons: (1) differences in air pressure between the soil and the house, (2) the presence of openings in the house's foundation, and (3) increases in permeability around the basement (if one is present).

      In constructing a house with a basement, a hole is dug, footings are set, and coarse gravel is usually laid down as a base for the basement slab. Then, once the basement walls have been built, the gap between the basement walls and the ground outside is filled with material that often is more permeable than the original ground. This filled gap is called a disturbed zone.

      Radon moves into the disturbed zone and the gravel bed underneath from the surrounding soil. The backfill material in the disturbed zone is commonly rocks and soil from the foundation site, which also generate and release radon. The amount of radon in the disturbed zone and gravel bed depends on the amount of uranium present in the rock at the site, the type and permeability of soil surrounding the disturbed zone and underneath the gravel bed, and the soil's moisture content.

      The air pressure in the ground around most houses is often greater than the air pressure inside the house. Thus, air tends to move from the disturbed zone and gravel bed into the house through openings in the house's foundation. All house foundations have openings such as cracks, utility entries, seams between foundation materials, and uncovered soil in crawl spaces and basements.

      Most houses draw less than one percent of their indoor air from the soil; the remainder comes from outdoor air, which is generally quite low in radon. Houses with low indoor air pressures, poorly sealed foundations, and several entry points for soil air, however, may draw as much as 20 percent of their indoor air from the soil. Even if the soil air has only moderate levels of radon, levels inside the house may be very high.

       

     

    What is Radon?

    • Radon is a radioactive gas that is found in every state in the U.S.
      It silently enters your home through the soil.  You can not smell, taste, see, or feel radon.
       

     


    What Makes Inspections First Qualified?

    • Inspections First is State Certified & a Member NRSB (National Radon Saftey Board) To provide measurement of cancer causing radon.
     

     


    My neighbor checked for radon and his house is ok, does that mean my house is ok?

    • No, radon can be low in the neighbors house and high in yours.
       

     


    When is the best time to check for radon?

    • Anytime, but many people check radon before purchasing a house.  
      Then you can negotiate with the seller to remove the high radon before the home is purchased.
       

     


    How is Radon Measured?

    • There are several accepted methods to measure radon.  
      Inspections First uses highly accurate, calibrated electronic monitors that are EPA approved. 

     


    How high can the Radon be before I take action?

    • EPA recommends that if your results are 4 pico curies or higher that you take action to reduce the levels of Radon in your home. 

     


     

    If the Radon is high, what should I do?

    • EPA recommends that you call a qualified Radon contractor. 
    • A qualified contractor has been trained to efficiently lower the radon in your home. 

     


    How much does it cost to measure?

    • Normally around $125  But there are package discounts availible with your home inspection.

     


    How much does it cost to lower Radon levels?

    • Normally between $800 and $2500 depending on the home design, soil conditions, and the age of the home.

     


    How long does it take to fix?

    • Usually 1 to 3 days.
