What is the recommended action for a client planning to renovate their home concerning radon testing?

For a client planning to renovate their home, the recommended action is to perform a short-term test before and after the renovation. This approach is effective because renovations can disrupt the existing air flow and structural integrity of the home, potentially affecting radon levels.

Conducting a short-term test before the renovation provides a baseline measurement of radon levels, allowing the homeowner to understand the existing radon situation. After the renovation, performing another short-term test is crucial as it can reveal any changes in radon levels caused by the renovation activities.

This dual testing strategy also helps to identify whether any new construction materials or changes in the home’s ventilation have introduced or increased radon levels. It is essential to monitor radon levels, especially during times of significant changes like renovations, to ensure that the home remains safe for its occupants.

Other options, such as performing only a long-term test, ignoring radon testing, or testing only after the renovation, miss the opportunity to establish a baseline and assess the impact of the renovations effectively. Hence, testing both before and after helps ensure a comprehensive analysis of the radon situation in the home.
