The seller had mitigation done before listing - the post-mitigation test shows 1.8 pCi/L. Should I believe that result?
Illinois has specific rules for radon measurement and mitigation work, so the safest public answer is to keep this practical. Use properly licensed radon professionals, keep clear records, and rely on a current radon result when deciding what to do next. If the result is elevated or confusing, Bill can explain what mitigation would involve and how a properly installed system should be approached.
Question linkMy tenant says their consumer monitor shows 4.8 pCi/L in the unit they're renting from me. What are my obligations?
For the radon side, focus on a reliable current reading and a clear mitigation path if the level is elevated. Real-estate paperwork, repair allowances, rental responsibilities, and closing decisions should be handled by the people managing the transaction. Bill can help with the practical radon part: what the number means, whether mitigation makes sense, and what a proper system would involve. If the reading is 4.0 pCi/L or higher, EPA recommends fixing the home. Between 2.0 and 4.0 pCi/L, EPA says to consider mitigation, especially if the space is used often.
