There is no truly safe level of radon — but the EPA sets 4.0 pCi/L as the action level, the point at which it recommends installing a mitigation system. Any Twinsburg home testing at or above 4.0 pCi/L should be mitigated.
What the Numbers Mean
Radon is measured in picocuries per liter (pCi/L). The EPA recommends action at 4.0 pCi/L and suggests homeowners consider mitigation between 2.0 and 4.0. The World Health Organization recommends an even lower threshold of 2.7 pCi/L. Because radon risk is cumulative, lower is always better — most mitigation systems we install in Twinsburg bring levels well below 2.0 pCi/L.
Why It Matters in Twinsburg
Twinsburg sits in Summit County, an EPA Zone 1 area where the predicted average indoor radon level already exceeds 4.0 pCi/L. That makes testing the only way to know where your home stands. If you have never tested, a short-term radon test gives you a clear answer in 48 hours.
If Your Level Is High
A reading above 4.0 pCi/L is fixable. A radon mitigation system uses sub-slab depressurization to pull radon out from beneath your foundation and vent it safely above the roofline. Get a free quote or call (330) 555-8201.
