How do nuclear gauges work? Why does so much care need to be taken when using them? - AnswerNuclear gauges use the interaction of radiation with matter to measure the density and moisture of material. Radiation sources within each gauge transmit radiation through the test material. Detectors contained in the gauge measure the radiation that is scattered by the test material or that passes through it. By calculating the percentage of radiation that reaches the detectors, the gauge can determi...
