If your Fairfax test came back between 2 and 4 pCi/L, you may be unsure whether radon mitigation makes sense yet.
What applies in Fairfax
For readings of 2.0 to 3.9 pCi/L, Linn County's chart recommends testing again, since one test is a snapshot of a few days [1]. If the second test lands in the same range, the county calls a fix a personal decision that weighs cost against risk [1].
Who sells radon kits near Fairfax?
Linn County Public Health sells both short- and long-term kits at 1020 6th St. SE in Cedar Rapids, or you can order one by phone at 319-892-6000 [1].
Should a Fairfax home with a very high first result run a long-term test?
No. For a first result of 8 pCi/L or more, Linn County's chart says to follow up with a short-term test within the next few weeks under closed-house conditions, not a long-term one [1].

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.
