During radon mitigation, which of the following is essential for device performance?

Regular calibration is essential for device performance during radon mitigation because it ensures that the measuring tools are providing accurate and reliable readings. Calibration involves comparing the measurements from the Radon measurement device with a known standard and making necessary adjustments to maintain precision. Over time, devices can drift from their accurate settings due to various factors such as temperature changes, wear and tear, or environmental conditions, making regular calibration crucial to maintaining compliance with safety standards and effectively monitoring radon levels.

Although device replacement and monitoring indoor temperatures can be important for overall indoor air quality and equipment maintenance, they do not directly impact the performance reliability of a radon measurement device in the way that regular calibration does. Ensuring airflow consistency can help in the overall effectiveness of radon mitigation strategies but does not pertain specifically to the performance of the measurement device itself. Therefore, the focus on regular calibration emphasizes the integrity and accuracy of the radon measurement process.
