Two Ways to Test for Radon 

Short-term Testing:   This type of test remains in the home for usually 2 to 90 days depending on the kit purchased. The test container is placed in the lowest lived-in level of the home for the recommended length of time, then sealed and returned to the company for analysis.

Specific instructions for placement and timing of the test are included with the test kit, so be sure to read and follow them carefully. The cost of the kit generally includes the sample collection container and the analysis.

Long-term Testing:   These tests remain in the home for more than 90 days, and will give a reading that is closer to the home's year-round average radon level.

You can order both short- and long-term radon test kits from the National Safety Council.

Radon Test Results:   What do they mean?

[Note: Radon gas is measured in “picocuries per liter of air” or pCi/L.]

If the short-term test result is 4 pCi/L or higher, you should confirm this by either:   

  •  a long-term test,   or
  •  another short-term test.

If the long-term test or the average of the 2 short-term tests is 4 pCi/L or higher, some action should be taken to fix the home.

You may even consider mitigating your home if the results are between 2 and 4 pCi/L.  There is no "safe" level of radon exposure.  (The average level of radon in outdoor air is 0.4 pCi/L.)

With the technology that is available today, radon levels in most homes can be reduced to 2 pCi/L or below.

For radon mitigation, using a certified radon mitigation contractor is recommended.
