Test again to confirm these results. EPA recommends that, if your initial short-term test results are 4 pCi/L or higher, you consider performing a second test to verify the results. The higher your initial short-term test results are, the more reason you have to choose a short-term follow-up test over a longer-term follow-up test. If your second round of test results are still at or above 4 pCi/L, EPA recommends taking action against radon.
