    No matter where you live in NC, it is important to test your home for radon.  Radon levels can vary widely from house to house, so it is best not to rely on the test results of your neighbors to determine if you have a radon problem in your home.   
     

There are two types of tests that can be used to test the air in your home for radon: a long-term test and a short-term test.

 
     

Long-term Test: A long-term test runs for at least 3 months and can run for up to a year.  The advantages of a long-term test are that you get a more accurate reading of the radon levels in your home over an extended period of time.  If your house tests 4 pCi/L or more on a long-term test, you should hire a radon mitigator to fix your home. One long-term test is considered sufficient evidence to make the decision about whether to fix your home.

    Short-term Test:  A short-term test runs for at least 48 hours and as long as one week.  The advantages of a short-term test are that you can get an idea of what the radon levels are in your home very quickly.  However, the decision to mitigate your home should not be based on the results of one short-term test.  At least two short-term tests should be conducted in the same location in your home.  If the average of the two tests is 4 pCi/L or greater, you should hire a mitigator to fix the radon problem in your home.

    Radon in Water Test:  Radon in water is not a concern for those on public water supplies.  Radon in water tests should be reserved for those on private or community well water.  The health concern from radon in water is that the radon will gas out of the water and into the air where it can be inhaled (for instance, while showering).  Ingestion of radon through drinking water is not a considerable health concern.  Therefore it is recommended that you test the air in your home with one of the tests above in addition to testing the water, as radon in air is the primary health concern.
