On this page: e. Doing a Short-Term Test...

If you are testing in a real estate transaction and you need results quickly, any of the following three options for short-term tests are acceptable in determining whether the home should be fixed. Any real estate test for radon should include steps to prevent or detect interference with the test device.

Short-Term Testing Options Passive: Take two short-term tests at the same time in the same location for at least 48 hours.

or Take an initial short-term test for at least 48 hours. Immediately upon completing the first test, do a second test using an identical device in the same location as the first test.

Active: Test the home with a continuous monitor for at least 48 hours.

What to Do Next Fix the home if the average of the two tests is 4 pCi/L or more.

Fix the home if the average of the two tests is 4 pCi/L or more.

Fix the home if the average radon level is 4 pCi/L or more.

When Choosing a Short-Term Testing Option...

There are trade-offs among the short-term testing options. Two tests taken at the same time (simultaneous) would improve the precision of this radon test. One test followed by another test (sequential) would most likely give a better representation of the seasonal average. Both active and passive devices may have features which help to prevent test interference. Your state radon office can help you decide which option is best.
