All this talk about radon measurement and radon mitigation can get a bit confusing, so we will try to make it easier to understand. This is important, not only to understand these terms and what they mean, but for the health and safety of your family! We have family too and are passionate about getting the word out about radon testing and helping our customer's find solutions to reduce the amount of radon found within their home.  

     Radon measurement - Obtaining a sample of the air or water from within your home and measuring the amount of radioactive gas found. This is usually measured in picocuries per liter of air (shown as pCi/L).  It can also be measured as working levels (WL).

     Radon mitigation - The steps taken to reduce or lesson the amount of radon within your home.

Air:  At All Radon Removal for radon air measurement, we use a 2-7 day air test. This is considered a short test. Once the test period is completed, the envelope is sealed and sent to the laboratory. Results are sent to the home owner and to us. This allows both parties involved to receive the results. We will discuss with you the appropriate actions that may need to be taken to reduce or mitigate the amount of radon in the air.

Depending on the outcome of the testing, a second 2-7 day air test may be necessary. Once the 2nd air test has been conducted, the average between the two results is calculated. This will be the number used to see if mitigation is necessary.

There are longer radon air tests that can be performed, between 90 days up to a year. This can provide a better overall cycle of the radon in your home.  Call us for more information on this type of testing.

Water:  At All Radon Removal for radon water measurement, we will take a sample of your water from a faucet and mail this to the laboratory for analysis. These results will come back to the home owner and to us. Again, this allows both parties to receive the results. We will work with you on the options for mitigation if necessary.  

Results:  The radon test results are usually received a few weeks after the radon air and radon water testing have been completed and the test packet(s) sent to the laboratory for analysis.  

Once the test results are in, All Radon Removal will work with you to provide the best solution in mitigating (reducing) the radon from your air and water.

Radon & My Home:  All homes should be tested for radon. It doesn't matter if the house is old or new, radon can still get into your home. Homes with or without basements should be tested. If your home is drafty or well-sealed, you should still test for radon within your home since the gas could still infiltrate any cracks or openings in the foundation. The radon gas comes from the natural decaying of uranium within the soil, rock and water near your foundation. Some levels are higher in certain areas of the United States.

Safe levels of radon - According to the EPA (Environmental Protection Agency), there are really no safe levels.  The below table shows risk levels and recommendations for mitigation:

High RiskTest results above 4.0 pCi/LMitigation strongly recommended
Moderate Risk       Test results between 2.0 and 4.0 pCi/L                       Mitigation recommended
Low RiskTest results below 2.0 pCi/LMitigation optional

                                                               (pCi/L stands for picocuries per liter of air)

The average outdoor level for radon is .4 pCi/L.

Even the house next door could have a different radon gas levels than yours.  Every home needs to be tested!

How often & Why should I test for radon?  There are a few factors to consider when answering the question of how often & why to test for radon. Here are a few reasons to test again:

  • If you plan to sell your home, most buyers want to see a radon test report dated within 2 years
  • If renovations or remodeling has occurred recently within your home
  • If you plan to occupy the basement level soon (a family room or home office)
  • Every few years a radon air test can be performed for your own peace of mind

On the same note, if you are buying a home soon, you will want to make sure a radon air test has been performed and the results are with your realtor.

The EPA and the U S Surgeon General recommends all homes be tested for radon.
