Which quality assurance practice involves confirming that measurements from different devices align?

The practice that involves confirming that measurements from different devices align is known as Comparison Checks. This process is essential in ensuring consistency and reliability in radon measurement results across various measurement devices. By performing comparison checks, professionals can determine if the devices yield similar readings under the same conditions. Such checks help identify any discrepancies that may exist between devices, which is crucial for maintaining the accuracy of radon assessments.

Calibration refers to adjusting a device to ensure its accuracy; verification involves confirming that a process or measurement system is functioning correctly, typically against established standards; and measurement validation is about ensuring that the measurement process accurately represents the intended measurement results. While these other practices are important in quality assurance, they focus on different aspects of measurement reliability instead of directly aligning results from multiple devices.
