1. Local risk is real
Zone 1 geology plus common basement construction means soil gas has plenty of paths indoors. Winter closed-house conditions often raise measured levels.

Why Cedar Rapids Homes Need Radon Attention
Radon is a colorless, odorless radioactive gas that forms naturally when uranium in soil and rock breaks down. It moves up through soil and can enter homes through cracks, sump pits, floor drains, and porous foundation walls. You cannot see or smell it — the only way to know levels in your house is to test.
Iowa is entirely EPA Zone 1 (highest predicted potential). Statewide surveys have found roughly seven in ten Iowa homes at or above the EPA action level of 4.0 pCi/L. Linn County Public Health treats radon as a local priority and sells test kits from its Cedar Rapids office. That does not mean every Cedar Rapids home is high — but it does mean testing is not optional curiosity. It is a basic health step for basements, finished lower levels, and homes sealed tight through Iowa winters. For the sourced numbers and what Linn County Public Health recommends at each result level, see our Linn County radon facts.
2. DIY kits miss context
A kit can be useful, but placement, closed-house timing, and follow-up decisions still matter — especially before a real-estate deadline.
3. Mitigation is proven
Active soil depressurization systems routinely bring elevated homes below 4.0 pCi/L when designed and installed by credentialed specialists.

Frequently asked questions
Is Cedar Rapids, Iowa in a high radon area?
Yes. Linn County and all of Iowa are mapped as EPA Radon Zone 1 — the highest predicted potential. Statewide survey data has found roughly seven in ten Iowa homes at or above 4.0 pCi/L. Testing is the only way to know your home’s level.
What radon level means I should fix my home?
The U.S. EPA recommends mitigating at 4.0 pCi/L or higher. Many homeowners also consider action between 2 and 4 pCi/L, especially if they use a finished basement daily. Call (319) 320-1100 to discuss testing or mitigation next steps.
Do Iowa technicians need a radon license?
Yes. Under Iowa Code chapter 136B, anyone who tests for radon or performs radon mitigation for compensation must be certified or credentialed by Iowa HHS; owners working on their own building, and unpaid work, are exempt. Cedar Rapids Radon Solutions is a referral service, not a radon contractor. We connect you with independent local specialists, and you can check any specialist on the Iowa HHS lists.
Should I test before buying a home in Linn County?
Iowa does not mandate a radon test to close, but sellers must disclose known results and provide the Iowa Radon Home-Buyers and Sellers Fact Sheet. Buyers in Zone 1 markets commonly test during the inspection period so elevated results can be negotiated.
What is the next step if my test is high?
Confirm the result if needed, then schedule radon mitigation with a local specialist. Most homes use an active soil depressurization system. Call (319) 320-1100 for a quote after a foundation review.
