2026 InterNACHI/AARST Radon Measurement Professional Practice Exam – Complete Prep Guide

When documenting a mitigation system in a home, including a statement that the system was observed, its operational status, and the limits of the inspection is crucial for a comprehensive report. This information ensures that the homeowner or other stakeholders are aware of the following:

1. **System Observation**: Noting that the system is present provides an important context for understanding the home’s radon mitigation status. It indicates that radon levels are being actively managed.

2. **Operational Status**: Including whether the system is operational or not helps inform about its effectiveness in reducing radon levels. A non-operational system would mean that the mitigation is not currently effective, which is vital information for health and safety considerations.

3. **Limits of Inspection**: Specifying the limits of inspection clarifies what aspects of the system were actually inspected (e.g., visible components only) and what might not have been fully assessed. This helps avoid misconceptions about the system's overall functionality and reliability.

This holistic approach to documenting the mitigation system provides a thorough understanding of the radon safety measures in place, enabling informed decisions regarding the property. Such detailed reporting aligns with best practices in radon measurement and mitigation.
