The Environmental Protection Agency (EPA) recommends that all homeowners test for radon in the homes, no matter the age of the home. You can purchase radon testing kits at your local hardware store, but be sure that you follow the directions to get an accurate reading.
How to Ensure Accuracy
While one test is enough to see how the radon levels are in your house, one tip to ensure accuracy is to buy multiple testing kits. Conduct the tests in different rooms of your home; not only will this tell you where different parts of the house read, but it will also help you determine what the average levels are all over the home.
Be smart and safe when conducting radon tests. Follow all directions and report to specialists immediately if you test higher than normal.
