In Lisbon, a high first reading is the usual reason to look at radon mitigation, and how high it is changes the next step.
Lisbon radon details
At 8 pCi/L and up, Linn County's chart says to retest with a short-term kit under closed-house conditions and advises against a long-term test, since exposure at that level could add risk [1].
Is there a radon hotline for Lisbon residents?
Yes. The state radon hotline at 1-800-383-5992 sells low-cost kits and answers questions from 8:30 a.m. to 4:30 p.m. Central. After hours, leave a message and staff will call back [2].
Where can Lisbon residents buy a kit from the county?
Linn County Public Health sells short-term and long-term kits. Call 319-892-6000, or visit the office at 1020 6th St. SE in Cedar Rapids [1].
Depending on your result, you may want radon testing, how a system works or crawl space radon. We gather the state rules for testers and mitigators in one place, how it works. Also covered: Cedar Rapids and Iowa City, plus all service areas.
Have a number from a test? Send a request.
We're a referral service, not a contractor. We send mitigation requests only to contractors on Iowa HHS's current credentialed list and testing requests only to state-certified radon measurement specialists, but we don't otherwise vet them, a referral is not an endorsement, and independent contractors may pay us for referrals.
