Nebraska Radon Program
Testing for Radon

Radon testing is recommended in all homes in Nebraska. Conducting a radon test is the only way to know how much radon you are exposed to. Fortunately radon testing is easy and inexpensive, and homes that have high radon levels can be easily fixed. If a home or building has an annual average radon level of 4 pCi/L or higher, it should be mitigated (fixed) to lower the radon level.

Short-term vs. Long-term Radon Tests
Short-term radon tests run typically from 2 to 7 days. They are useful as an initial screening test because they are inexpensive and the results are received quicker than long-term tests. Long-term tests run from 3 months to a full year and often give a better annual average of your radon exposure, since they can take into account the seasonal variations of radon.

Testing Your Home (Non-Real Estate Transactions)
If you want to know the radon level in your own home, you can conduct a test with a do-it-yourself kit. Follow the instructions that come with the test kit and place the kit in the lowest level where you spend time, preferably in a living room or bedroom. Do not test utility rooms, laundry rooms, or kitchens. If performing a short-term test, ensure windows are kept closed and entry/exit is kept to a minimum.

Steps to Testing Your Home

STEP 1 Start with a short-term test
  • If your first test is high (greater than 4 pCi/L), go to Step 2 and conduct a follow-up test.
  • If your first test is low (below 4 pCi/L), test again in 2 to 5 years, especially if your home is renovated or remodeled.
STEP 2 Perform a follow-up test
  • If your first short-term test was between 4 and 8 pCi/L, conduct either a long-term test or second short-term test and go to Step 3. 
  • If your first short-term test result was 8.0 pCi/L or higher, conduct another short-term test to verify the results of the initial test and go to Step 3.
STEP 3 Reduce Radon
  • If the follow-up test is higher than 4.0 pCi/L, fix your home to reduce radon levels. If the annual average radon level is between 2 and 4 pCi/L, consider taking action to reduce radon levels.
Testing in Schools & Workplaces
Radon testing in schools, offices, and other workplaces must be conducted by a licensed Radon Measurement Business. The Environmental Protection Agency and the American Lung Association recommend that all schools should be tested for radon, and the Nebraska Radon Program will test a small number of schools each year free of charge.
