What is the primary function of the detectors in a nuclear gauge?

The primary function of the detectors in a nuclear gauge is to measure scattered and transmitted radiation. In the operation of nuclear gauges, these detectors play a critical role by capturing the radiation that is either transmitted through a material or scattered as a result of interaction with that material. This measurement is essential in determining the density, moisture content, or other properties of the material being tested.

Detectors convert the incoming radiation into a measurable signal, which can be quantified to provide accurate readings. The ability to measure both scattered and transmitted radiation allows for a comprehensive analysis of the material's characteristics, thereby making the gauge an effective tool in various applications such as construction, soil testing, and quality control in manufacturing processes.
