True or False: Most radon problems can be corrected through professional remediation.

The statement that most radon problems can be corrected through professional remediation is true. Radon remediation specialists employ a variety of techniques to mitigate elevated radon levels in homes and buildings. Common methods include active soil depressurization, sealing entry points, and improving ventilation systems, all of which can effectively reduce radon concentrations to acceptable levels.

The effectiveness of these remediation solutions means that many homes experiencing high radon levels can be made safer. It is important for homeowners to work with qualified professionals who understand the specific diagnostics and remedial tasks necessary to address radon issues.

In contrast, the other choices suggest limitations or exceptions not supported by the general consensus in the field. For instance, the claim that remediation is only possible in newly built homes underestimates the range of techniques available for older structures. Additionally, stating that studies have not confirmed remediation success discounts extensive evidence demonstrating the efficacy of professional practices in radon mitigation.
