Radon Testing in Toledo, Ohio
Radon is a colorless, odorless radioactive gas produced by the decay of uranium in soil and bedrock. The Ohio Department of Health classifies all of Lucas County as Zone 1 — the highest of three EPA risk tiers — which means an indoor test is the only way to know what a given home is sitting at.
Short-term continuous monitor
A continuous radon monitor is placed in the lowest livable level of the home for a minimum of 48 hours. The monitor logs hourly readings and the average concentration in picocuries per liter (pCi/L). The result is a written report showing the hour-by-hour graph, average reading, and a recommendation against the EPA action level of 4.0 pCi/L.
Short-term tests are appropriate for: real estate transactions, post-mitigation verification, and any homeowner who wants a quick read on whether the home needs further attention.
Long-term alpha-track test
For a more representative picture, an alpha-track detector is left in place for 90 days or longer. Long-term testing averages out seasonal variation — basements typically read higher in winter when homes are sealed up — and is recommended when a short-term result lands in the borderline 2.0 to 4.0 pCi/L range.
Real estate testing
Real estate radon tests follow stricter protocol: closed-house conditions for 12 hours before and during the test, no monitor relocation, and a documented chain of custody. Results are turned around within 24 hours of pickup so closings stay on track. See real estate radon testing for the transaction-specific process.
What a typical Toledo result looks like
Indoor levels in the Toledo metro commonly fall between 2.0 and 8.0 pCi/L on a finished basement, with older masonry foundations and homes near the Maumee River escarpment trending higher. A level over 10 pCi/L is uncommon but does happen on poured slabs over fractured shale — and is the strongest case for mitigation.

FAQ
How long does a radon test take?
A short-term continuous monitor runs for at least 48 hours in the lowest livable level of the home. Long-term alpha-track tests run 90 days or longer for a more representative average.
Where is the test placed?
In the lowest level that is, or could reasonably be, lived in — usually a finished basement or first floor over a slab. Placed away from drafts, exterior doors, and HVAC vents per AARST-NRPP protocol.
What level requires action?
The U.S. EPA recommends mitigation at 4.0 pCi/L or higher. Levels of 2.0 to 3.9 pCi/L are also worth reducing.
