You can't see radon, but it's not hard to find out if you have a radon problem in your home. All you need to do is test for radon.
The amount of radon in the air is measured in "picocuries per liter of air," or "pCi/L." There are many kinds of low-cost "do-it-yourself" radon test kits you can get through the mail and in hardware stores and other retail outlets, but you need to make sure you follow all the recommendations about placement and maintaining closed house conditions. If this is not done, your test results will not be reliable.
If you are buying or selling a home, hire a qualified radon tester to do the testing for you.
There are Two General Ways to Test for Radon:
- The quickest way to test is with short-term tests. Short-term tests remain in your home for two days to 4 days, depending on the device. "Charcoal canisters," "alpha track," "electret ion chamber," "continuous monitors," and "charcoal liquid scintillation" detectors are most commonly used for short-term testing.
- If you need results quickly, however, a short-term test followed by a second short-term test may be used to decide whether to fix your home.
