How can the accuracy of monitors be assured according to standard practices?

The accuracy of monitors can be assured through annual calibrations, which is a standard practice in monitoring environments for various instruments, including radon detectors. Calibration ensures that the monitor is providing accurate readings by comparing it to a known standard or reference. This process adjusts the instrument's output to account for any drift or changes that may occur over time due to environmental factors or internal wear. By adhering to a regular calibration schedule, technicians can maintain the reliability and precision of the monitoring equipment, ensuring that data collected is valid and trustworthy.

Regular bias testing can also contribute to accuracy, but calibration directly addresses the necessary adjustment needed to ensure specific measurements are correct. Increasing test frequency may improve data quantity but does not directly assure the accuracy of the instruments if they are not calibrated properly. Using only one monitor may limit the ability to cross-verify data for accuracy, as having multiple instruments can help identify inconsistencies. Therefore, establishing a thorough and consistent calibration routine is paramount in upholding the standard practices of monitor accuracy.
