How often should continuous radon monitors be calibrated?

Continuous radon monitors should be calibrated once per year to ensure their accuracy and reliability in measuring radon levels. Calibration is crucial because it verifies that the device is functioning correctly and producing valid results. Over time, the sensitivity of detectors can change due to factors such as environmental conditions, wear and tear, or changes in technology. Annual calibration helps maintain the monitor's performance, ensuring that the readings are consistent with established standards and regulations.

Calibration should be conducted using a recognized standard method by an accredited calibration laboratory. This regular maintenance is essential for professionals conducting radon measurements to provide trustworthy services and protect public health effectively. In contrast, calibration intervals shorter or longer than one year could lead to either unnecessary expense or the risk of inaccurate measurements, respectively.
