After installing a radon mitigation system, it's crucial to run post-mitigation radon testing to ensure the fix actually worked. This typically involves placing test devices in the lowest livable area for a period of 48 hours to several months, then sending them to a lab for analysis. The results confirm whether radon levels have dropped below the EPA's recommended action level of 4 pCi/L, giving homeowners peace of mind that their family's exposure is minimized.
