What should be done prior to conducting measurements with a nuclear gauge?

Prior to conducting measurements with a nuclear gauge, it is essential to conduct a visual inspection and perform a calibration check. This process ensures that the gauge is in proper working condition and provides accurate and reliable measurements. A visual inspection allows the operator to identify any physical damage or wear that could affect performance, such as damaged cables, cracked housing, or loose components.

Performing a calibration check is equally important, as it verifies the gauge's accuracy by comparing its output against known standards. If a gauge is not properly calibrated, the measurements it provides could be significantly off, leading to incorrect data and potentially unsafe conditions.

While reviewing previous measurement logs, charging the battery, and notifying the regulatory agency are also important aspects of operating a nuclear gauge, they do not directly ensure the immediate accuracy and safety of the measurements being taken at the time of use. Proper function and calibration take precedence in this context to maintain safety standards and measurement integrity.
