How are the test results interpreted?
1. If the short-term test result is 4 pCi/L or higher, conduct a follow-up test to confirm the results. 2. Follow-up with either a long-term test or a second short-term test. For a better understanding of the home’s year-round average radon level, take a long-term test. If results are needed quickly, take a second short-term test. The higher the initial short-term result, the more certain the homeowner can be to conduct a short-term rather than a long-term follow-up test.
