What do control charts primarily track in relation to radon testing?

Control charts are essential tools in monitoring processes over time, particularly in the context of radon testing. They are primarily used to evaluate the precision, accuracy, and bias of measurement methods, ensuring that the data collected is reliable and consistent. In radon testing, control charts help specialists track variations in measurements, allowing them to identify any unusual patterns that may indicate problems with the testing process or the instruments being used.

By focusing on the precision and accuracy of the measurement process, control charts assist in validating that the radon concentrations reported are trustworthy. This, in turn, helps ensure that any necessary remedial actions based on the data collected are grounded in solid, reliable information. The use of control charts is crucial for maintaining high standards in testing procedures and ensuring that radon mitigation efforts are based on accurate assessments of radon levels.
