What is the minimum wait time to test for radon after a mitigation attempt?

The minimum wait time to test for radon after a mitigation attempt is indeed 24 hours. This timeframe is recommended to ensure that the radon system has stabilized and that any air movement created by the mitigation process has settled down. Testing too soon after mitigation could lead to inaccurate results due to residual effects of the mitigation process itself, such as fluctuations in air pressure or temporary changes in the radon level.

Allowing a full 24 hours before testing enables a more accurate assessment of the radon levels in the home after the mitigation measures have been implemented. This period ensures that the radon levels reflect the true condition of the indoor air quality after the system has been adjusted to its normal operational state. Following this guideline is crucial for homeowners and professionals involved in ensuring safe indoor environments.
