Radon testing in Iowa City: a 48-hour answer, not a mail-away guess.
Calibrated continuous radon monitors — not mail-away charcoal guesswork — placed and read by Iowa HHS-credentialed measurement specialists.
From $150 · Report delivered the same day the monitor comes down.
The problem
You can't see, smell, or taste radon — and in Iowa that matters more than almost anywhere: homes that get tested here average 10.15 pCi/L, two and a half times the EPA's action level.
Radon is the second-leading cause of lung cancer in the US, and every Johnson County ZIP code sits in EPA Zone 1. A $12 charcoal kit that sat in a store for a year, mailed to a lab and averaged into one number, tells you almost nothing about what your family actually breathes.
We place a calibrated continuous radon monitor for 48 hours and hand you an hour-by-hour graph the day it comes down — plus a plain-English recommendation. If you're under 4.0, we tell you so and leave. No scare tactics, no bundled upsell.

Frequently asked questions
Why not just use a hardware-store charcoal kit?
Charcoal kits give one averaged number, lose accuracy with humidity and shelf age, and take a week or more for lab results. Our continuous monitor logs every hour for 48 hours, flags tampering and weather swings, and you get the report the day it comes down.
What number should worry me?
The EPA action level is 4.0 pCi/L — fix at or above it, and consider fixing between 2.0 and 4.0. For context, Iowa's user-submitted average is about 10.15 pCi/L, so most Johnson County homes we test do come back above 4.0.
Do I have to keep windows closed during the test?
Yes — EPA protocol requires closed-house conditions starting 12 hours before the test and throughout the 48 hours. Normal entry and exit through doors is fine.
