If an initial short-term test result is 4 pCi/L or higher, what should be done next?
The EPA recommends a follow-up measurement be used to confirm whether radon levels are high enough to warrant mitigation by an electronic continuous monitor. If a short-term follow-up test is done and the result is 4 pCi/L or higher, radon mitigation is recommended for real estate transactions. In certain instances, such as may occur when measurements are performed in different seasons or under different weather conditions, the initial and follow-up tests may vary by a considerable amount. Radon levels can vary significantly between seasons, so different values are to be expected.
