Radon Test Kit

Radon is an odorless, colorless and tasteless gas produced by the decay of natural radioactive materials found in the soil. It’s a naturally occurring environmental hazard that seeps into homes and other buildings through joints or cracks in the foundation and has been found above recommended levels in as many as one in four homes in Kansas.

Radon is known to be the leading cause of lung cancer in non-smokers and the second leading cause of lung cancer in smokers, and testing is recommended.

Do-It-Yourself Air Chek radon test kits are available at the Johnson County K-State Research and Extension office
Following the directions provided with the test kits and detectors is important, so the results will reveal the potential for elevated concentrations in the lowest lived-in level of the home.

If your results are low, consider repeating the test every two or three years or whenever there is a significant change in the home’s foundation, heating system or air tightness from weatherization efforts.

If radon is present above the recommended ceiling (4.0 pCiL/Pico Curies per liter), a confirmatory test should be conducted. If you want to know the radon concentration in other areas of your home, conduct the desired number of tests at the same time. When high results are confirmed, experts recommend consulting a radon professional for mitigation system installation.

Fee: $8 each (Cash, credit card or checks — make checks payable to "Johnson County Extension Council")

Where to Purchase: Purchase your radon kits at our Extension office, Monday - Friday, from 8:30 a.m. - 5pm. Map to office.

Note: We are not able to mail or ship test kits.
