What Is Radon Testing?
Radon testing is conducted in several different ways, but all methods sample the air for the presence of radon gas and then the amount of gas found is reported back to you in quantities measured in picocuries per liter (pCi/L). Outside air typically measures between 0.2 to 0.8 pCi/L but levels inside of structures can be much, much higher. The only way to know is to test.
