DENSITY NUCLEAR GAUGE QUESTIONS AND ANSWERS...

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...

Before using a nuclear density gauge on a job, a ___________ __________ must be taken daily to determine if the gauge is operating correctly. - Answer-Standard count A suitable location for conducting a standard count is an ____________ surface, __________ feet away from large objects and _________ feet away from other nuclear gauges. - Answer-asphalt, greater than 10', greater than 60 The use of a nuclear density gauge for determining density of an asphalt pavement requires the determina...
