What 11.2 pCi/L means for your State Center home
The county number for State Center is 11.2 pCi/L, Marshall County's average in CDC-reported tests from 2008 through 2017, which ranks it 7th of 99 Iowa counties and 9 times the U.S. average. Polk County, next door to the metro, averages 7.3; Marshall County runs higher, and State Center homes test accordingly. What it cannot tell you is your own result; two houses on the same State Center street regularly land on opposite sides of the action level.
The county figure tells you the odds; a certified test tells you the answer. We place a continuous monitor in your State Center home for 48 to 72 hours and email the report the day it comes out. If it reads 4 pCi/L or higher, you get a written mitigation quote the same day, and every system we install is guaranteed below 2.7 pCi/L.
Free radon test kit for State Center homes
Yes. State Center is in a rural Iowa county covered by the state's free radon test kit program.
Healthy Hometowns: Combat Cancer, run by Marion County Public Health with local health departments across rural Iowa, provides one free radon test kit per household while supplies last. Request it through the program's order form, or ask Marshall County Public Health.
Request a free kit (Healthy Hometowns: Combat Cancer) →A free kit is a mailed charcoal test: results take a couple of weeks, one kit can miss a high reading, and it is not accepted for a real-estate sale. If it comes back at 4.0 pCi/L or higher, the next step is a certified 48-to-72-hour monitor test with same-day results, then a same-day mitigation quote.
The same program is funding mitigation help for rural homeowners whose homes test high. If your kit comes back at 4.0 pCi/L or above, call us: we confirm the number with a certified monitor test, quote a system the same day, and point you to your Marshall County program contact for any assistance you qualify for.

Radon in State Center Homes
Most of the homes in State Center (population 1,391, incorporated 1867) were built long before anyone thought about radon. Stone and block foundations, partial basements, and crawl spaces are the norm, which is exactly the kind of house where sealing and suction-point placement decide whether a system works.
State Center's 0.98 square miles hold about 1,419 people per square mile, classic Iowa small-town lots with room between houses. That usually means an exterior fan on the side away from the street and a vent run that stays off the front of the house, with the neighbors far enough away that fan placement is simple.
We reach State Center, 38 miles northeast of Des Moines, a routine drive for our crews, on regular routes. Our nearest other stops are Melbourne (6 mi), Colo (8 mi) and Collins (11 mi), so a State Center visit usually pairs with jobs nearby. Testing is a 48-to-72-hour continuous monitor with same-day results, and most mitigations finish in one visit, followed by a clearance test and our 2.7 pCi/L guarantee.

State Center Radon Questions
Does All Midwest Radon serve State Center, Iowa?
Yes. State Center is 38 miles northeast of our Des Moines base and inside our regular service area, along with the rest of Marshall County and nearby Melbourne, Colo, Collins. We test and mitigate homes in State Center on the same schedule as the Des Moines metro.
What is the average radon level in Marshall County?
The Marshall County average is 11.2 pCi/L in the CDC's 2008 to 2017 data, 7th of 99 Iowa counties. The EPA action level is 4. Averages describe the county, not your house: State Center homes land on both sides of the line, and only a certified test tells you which.
Can I get a free radon test kit in State Center?
Yes. Marshall County households can request one free short-term radon test kit through Healthy Hometowns: Combat Cancer, the state program for rural Iowa, while supplies last. A kit is a good first look, but results take weeks and it is not accepted for a home sale. A certified 48-to-72-hour monitor test gives same-day results, and any reading at 4.0 pCi/L or above should be confirmed that way before mitigation.
How long does radon mitigation take in State Center?
One visit for nearly every State Center home. The crew seals a suction point in the slab or sump, runs the pipe to an exterior fan on the least visible side of the house, terminates above the roof, and sets a clearance monitor. The result is guaranteed below 2.7 pCi/L.
Do State Center sellers have to test for radon?
No. Iowa Code chapter 558A is a disclosure law: a seller must disclose any known test results and provide the Iowa Radon Home Buyers and Sellers Fact Sheet, but no law requires the test itself. In practice the buyer orders a certified test during the inspection period. We schedule those seven days a week.
