Sensitivity in measurement methods is defined as what?

Sensitivity in measurement methods refers to the ability of an instrument or technique to produce reliable measurements even at low concentrations of a substance. This is crucial in contexts such as radon mitigation, where detecting low levels of radon gas is essential for assessing health risks and evaluating effective mitigation strategies.

A measurement method with high sensitivity can distinguish small variations in concentration, allowing for accurate readings even when the amount present is minimal. This is particularly important in situations where regulatory thresholds exist, and it is necessary to ensure that any levels detected are reported properly to ensure compliance with safety standards. Thus, understanding sensitivity helps practitioners select appropriate testing methods to effectively monitor and manage radon levels.
