How do you measure radon?
There are two ways to perform radon testing for a building. The most common test is referred to as a “short term test.” The short term test is the easiest and quickest way to test your home for radon. The test can take anywhere from two to 90 days depending on the device your technician uses. Be Safe uses what is called a “Continuous Radon Monitor,” that only requires 48 hours of continuous testing.
The second type of radon testing is what’s known as a “long-term test.” This test lasts for at least 90 days, and is used when attempting to get a general idea of your radon levels year round. The EPA recommends that you take the “short-term test.”
In certain circumstances, if your test levels come back more than 4pCi/L, your technician may recommend another test to be certain that the results are correct, and that there weren’t any outside variables that contributed to the high levels of radon. Short term radon testing requires that all doors and windows are closed for 12 hours prior to commencing the test.
Radon can also be present in your water supply. Typically it is only an issue if your water supply comes from a well or ground water, as opposed to surface water like in a reservoir or other open air sources.
