If the first short-term radon test result is double the EPA action level of 4.0 pCi/L, what should be done next?

If the first short-term radon test result is double the EPA action level of 4.0 pCi/L, what should be done next?

• A. Conduct a long-term test
• B. Take a second short-term test
• C. Install a ventilation system
• D. Ignore the result

Answer: (B)

When the first short-term radon test indicates a level that is double the EPA action level of 4.0 pCi/L, it is crucial to verify the result for accuracy before taking any significant action. Conducting a second short-term test is a recommended step because it helps to confirm whether the elevated radon level was due to temporary conditions, measurement error, or a genuine concern that needs addressing. Short-term tests can be influenced by factors such as weather conditions or if the home was being used in a way that affects air circulation during the test period. If the second short-term result confirms the elevated levels, it would warrant further action, like performing a long-term test or considering mitigation strategies. Taking the time to conduct a second short-term test ensures that a proper decision is made based on accurate data.
