Get a result you can act on.

Testing is the only way to know a home's radon level. The right method depends on whether you need an initial check, independent documentation, or a result on a real-estate deadline.

Match the test to the decision.

01
Initial home check
Best for a first screening result
A do-it-yourself short-term kit can be a practical screening step. Use an approved device, place it exactly as directed, and return it promptly to the listed laboratory.
02
Independent measurement
Best when the result needs independent documentation
A Nebraska-licensed radon measurement professional can place and retrieve the device and document the conditions. This is useful when the result must be independent.
03
Real-estate timing
Best when timing and shared records matter
Coordinate the method and timing with the parties to the transaction before testing. Avoid moving or disturbing the device, and keep a clear record of the test conditions.

Short-term test basics

Protect the test conditions.

Follow the device instructions first. Nebraska DHHS advises keeping windows closed and limiting entry and exit for a short-term test. Place the device in the lowest level that could be used regularly, away from drafts, exterior walls, high heat and high humidity unless the instructions say otherwise.

Do not improvise placement. Device instructions and the measurement professional's protocol control. Weather, ventilation changes, fans and disturbed devices can affect a short test.

Prepare

Confirm the test duration and establish the required closed-building conditions.

Place

Record the start time and location, then leave the device undisturbed.

Finish

End on time, record the details and return the device as directed.

Understanding the number

A result is a decision point, not a diagnosis.

The EPA recommends fixing a home at 4 pCi/L or higher and considering action between 2 and 4 pCi/L. A short-term result can vary, so the appropriate confirmation path depends on the level, test type and timing.

Before comparing a home result with a county map, read what Lincoln and Lancaster County radon data can—and cannot—tell you.

If the result supports action, review radon mitigation options in Lincoln and what affects mitigation cost. After installation, use the post-mitigation retesting plan to verify performance and schedule future checks.

Official guidance

Verify the method and the provider.

Nebraska DHHS maintains radon information, test-kit guidance and radon occupation licensing resources. EPA also explains where to obtain a kit and how to find credentialed professionals.
