Why This Matters
Quick Summary
- #2 cause of lung cancer (21,000 deaths/year)
- Ohio is EPA Zone 1 — highest risk
- Invisible, odorless, tasteless gas
- Levels vary house to house — testing is the only way to know
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths annually. It's a radioactive gas that forms naturally from the decay of uranium in soil and rock, and it enters buildings through cracks in foundations, gaps around pipes, and other openings. You cannot see it, smell it, or taste it. The only way to know if your home or building has dangerous radon levels is to test.
Northeast Ohio sits in EPA Zone 1, the highest-risk zone for radon exposure. This means the region's geology produces consistently elevated radon levels compared to much of the country. The EPA recommends action when radon levels reach 4.0 pCi/L or higher, but many homes in our service area test well above that threshold.
Many homeowners assume that because their neighbor's home tested fine, theirs will too. This is a dangerous misconception. Radon levels can vary dramatically from house to house — even between units in the same building — because they depend on the specific soil composition, foundation type, and ventilation patterns of each structure. The only way to know your level is to test your property.

How Bidemly Helps
Quick Summary
- Continuous monitors measure hourly for 48+ hours
- Tamper-evident equipment
- Results accepted by lenders and Ohio EPA
- Clear mitigation guidance if elevated
Bidemly provides professional radon testing using continuous radon monitors (CRMs) that measure radon levels every hour over a minimum 48-hour testing period. Unlike charcoal canisters that provide a single average, our CRMs produce an hourly data log that reveals patterns and prevents tampering. We follow all Ohio Department of Health testing protocols, and our results are accepted by lenders, real estate agents, and the Ohio EPA. If elevated levels are found, we provide clear guidance on mitigation options.
