Radon Testing in Galena, Ohio

Radon Testing in Galena, Ohio: What Local Data Shows

Galena homes often include full basements, walkouts, and larger footprints, features that can create strong pressure effects and multiple soil-gas entry pathways.

Because of that, elevated radon readings in Galena are not unusual. The best approach is to expect the possibility, test correctly, and treat mitigation as a normal solution when needed.

Galena Radon Data Snapshot (From My Local Dataset)

In my dataset of 106 total radon tests, 18 tests were from Galena addresses.

Galena (n = 18 tests):

Average (mean): 8.01 pCi/L
Median: 8.50 pCi/L
Highest recorded: 10.9 pCi/L
Homes at/above 4.0 pCi/L: 100% (18 of 18)

EPA action level: 4.0 pCi/L

That “100% at/above 4.0” figure is extremely useful for setting expectations: in this Galena sample, elevated radon wasn’t occasional, it was consistent.

Why Galena Often Tests Elevated

Common contributing factors include:

Delaware County soil conditions
basement and sump features
stack effect in larger homes
multiple foundation penetrations

High radon in Galena typically reflects regional conditions, not construction quality.

commonly handled through mitigation systems that are designed for exactly this situation

How This Radon Data Was Compiled

The statistics on this page are based on 106 professional radon tests performed in Central Ohio residential properties.

Each test was:

Conducted during a real estate transaction or property evaluation
Measured using professional-grade continuous radon monitors
Performed according to industry standards
Documented and archived

City-specific statistics reflect radon tests performed at properties located within that municipality.

Because radon levels can vary from home to home, these figures are intended to provide regional context, not predict results for any individual property.

Testing remains the only way to determine a specific home's radon level.
