Nuclear gauge testing nuclear moisture density gauges are testing devices that use low level radiation to measure the wet density dry density and moisture content.
Nuclear density gauge test procedure. Percent density and the moisture content from the nuclear gauge is compared to the optimum moisture limits. Pretest warm up procedures for the 3440 nuclear gauge the standard count should be taken daily before any testing is done to check gauge operation and allow the. This test method describes the procedure for determining the in place density and moisture of earthwork through the use of a nuclear gauge. The density of the material shall be determined by direct transmission and the moisture content shall be determined by backscatter.
Nuclear densitometry is a technique used in civil construction and the petroleum industry as well as for mining and archaeology purposes to measure the density and inner structure of the test material the processes uses a nuclear density gauge which consists of a radiation source that emits particles and a sensor that counts the received particles that are either reflected by the test.
