What is the minimum time a radon mitigation system should operate before conducting post-mitigation testing?

• A. 12 hours
• B. 24 hours
• C. 48 hours
• D. 72 hours

Answer: (B)

The minimum time a radon mitigation system should operate before conducting post-mitigation testing is 24 hours. This timeframe allows the system to stabilize and effectively reduce radon levels within the home. Initially, when a mitigation system is activated, it may take some time for the system to reach its optimal performance and for the indoor air to reflect the changes in radon concentration. Sufficient time is crucial to ensure accurate measurement results. Testing too soon could yield misleading results, as the radon levels may not have dropped significantly or stabilized into a consistent range. Therefore, waiting at least 24 hours is essential for reliable post-mitigation testing results, enabling homeowners to assess the efficacy of the mitigation system accurately.
