What is required to evaluate the effectiveness of radon mitigation?

To evaluate the effectiveness of radon mitigation, conducting one or more short-term tests is essential. This approach allows for a quick assessment of radon levels in the home after mitigation measures have been implemented. Short-term tests typically last from a few days to a week and can effectively indicate whether the mitigation system is functioning as intended.

By comparing the results of the short-term tests to the established action level for radon, it can be confirmed if the mitigation efforts have reduced radon concentrations to safe levels. If levels remain high, further evaluation of the mitigation system may be necessary to identify and resolve potential issues.

While long-term tests and continuous monitoring provide valuable data over extended periods, they are not typically used immediately following mitigation. Using short-term tests is an efficient way to gather timely information on the effectiveness of the mitigation system, making them the most appropriate choice for this evaluation process.
