Radon Testing
There are a number of methods for testing for radon. The most common is a short-term test using one or more charcoal canisters. The canisters are placed in the home for 48 hours (min.), after which they are sent to a laboratory for analysis. The results of the test tell you what the average concentration of radon was in your home at the time of the test. Special monitoring equipment can also be used that provide results immediately after the sampling period is completed.
If the short-term test's results are above the EPA threshold of 4.0 picocuries per liter (pCi/L) but below 10 pCi/L, it is recommended that you take a long-term test. A long-term test lasts at least 90 days and give a more reliable sampling of the radon levels in your home. Decisions concerning mitigation actions should be based on the findings of the long-term test.
If your initial test comes back above 10 pCi/L, the EPA recommends that you take a second short-term test immediately to confirm the results of the first test. If the average of the two tests is above 4.0 pCi/L, the EPA recommends mitigation action be taken.
Other testing methods that utilize real-time monitoring equipment are also available. The benefit of real-time measurements is that you get immediate results — you don't have to wait to receive your results back from the lab.
Radon can also be an issue if buying or renting a home. Because real estate sales happen quickly, there is often insufficient time to perform the long-term test. Therefore, short-term tests are usually preferred. For more information regarding radon and home sales, checkout the EPA's Home Buyer's and Seller's Guide to Radon.
