About
Your neighbor who actually checked.
Hi, I'm Tipper. I test the smoke detectors on the first of every month, keep the gutters clean before it rains, and yes, I've tested my home for radon twice.
Most people haven't. The information is scattered across dry government pages, manufacturer-owned tools with obvious bias, and contractor lead-gen sites designed to hand off your contact info. Nobody built the independent resource that just answers the question: what is my risk, and what should I do about it?
So I did.
RadonLookup pulls county-level data from the EPA and CDC, presents it in plain English, and connects it to practical next steps. The guides are written the way I'd explain something to a neighbor on a Sunday afternoon. No alarm, no spin, and no steering you toward a product I don't believe in.
I cite everything. I explain the limits of the data. And when I recommend a test kit or a contractor practice, it's because I'd hand that recommendation to someone I care about.
How this site works
No contractors pay to be listed here. No test kit manufacturers sponsor the guides. RadonLookup earns through affiliate commissions on products Tipper genuinely recommends. The recommendation comes first, always.
Every risk number, zone classification, and health claim links back to the EPA or CDC. If something can't be sourced, it doesn't go on the site.
The government data exists. The problem is that nobody explains what it means for a real homeowner. That's the gap this site fills.
Radon is a real risk worth taking seriously, and it's a manageable one. The goal here is calm, accurate information.
Where the data comes from
RadonLookup does not generate its own radon measurements. All risk data is sourced from federal agencies.
County-level zone classifications (Zone 1, 2, 3) based on EPA geological and indoor measurement surveys.
Measured county-level radon averages from actual home test results, reported in pCi/L.
County averages reflect CDC-reported measured indoor radon levels and may have small sample sizes in less-populated counties. EPA zone classifications are based on geological surveys and are intended as area-level predictors, not guarantees for individual homes. Always test your specific home.
Affiliate disclosure
Some links on RadonLookup, particularly in the test kit guides, are affiliate links. If you purchase through one of these links, RadonLookup earns a small commission at no extra cost to you. This is how the site pays for itself without charging users or taking money from contractors. Tipper only recommends products he'd actually use or hand to a neighbor.
