Is there a safe level of radon?

The Ohio Department of Health estimates that one-half of Ohio homes have radon levels above the Environmental Protection Agency’s recommended action level of 4.0 pCi/L.  To find the average indoor radon levels of all Ohio counties, as determined by radon test results from Air Check, Inc., click here.

Any amount of radon carries some risk, even at or below the recommended action level. The risk of lung cancer increases with higher long-term average radon levels. Because it isn’t possible to reduce radon to zero, the best approach is to lower levels as much as possible. In Ohio, there are no regulations requiring that radon be reduced, so people must decide how much radon they feel is acceptable in their homes.

The Environmental Protection Agency has published several helpful guides about radon, including “A Citizen’s Guide to Radon,” “Home Buyer’s and Seller’s Guide to Radon,” and “Consumer’s Guide to Radon Reduction.”
