Option 1: The Extension-Office Kit (about $10)

Kansas runs one of the country’s most accessible test-kit programs: short-term kits are sold at K-State Research & Extension county offices, typically for about $10. For Topeka, that’s the Shawnee County Extension office, 1740 SW Western Ave ((785) 232-0062) — call ahead for current price and stock. For a first answer on your own home, this is the best ten dollars in home maintenance.

Option 2: A Certified Measurement Professional

Kansas’s radon certification law means anyone measuring for pay must be KDHE-certified — and for any number that has to stand up to scrutiny (a home sale, a dispute, a mitigation decision), certified measurement with calibrated continuous monitors is the standard. Transaction testing has its own protocol; see radon and home sales.

Running a Valid Test

Closed-house conditions starting 12 hours before and throughout: windows shut, doors closed except normal use. Place the device in the lowest lived-in level — the basement rec room you actually use, not a crawl space — away from drafts, exterior walls, and humidity. Short-term kits run 2–7 days; mail promptly. Winter readings run closest to your worst case.

Reading Your Result

Under 2.0 pCi/L: good — retest every two years and after major work. 2.0–3.9: below the action level, but the EPA suggests considering mitigation; retest to confirm. 4.0 and up: the action level — mitigate. Context for Kansas nerves: the state average is 5.4, about 1 in 4 homes runs high, and the average mitigated home lands at 1.2. A high first test here is common, and fixable.
