Nuclear densometer Wikipedia

A nuclear densometer is a field instrument used in geotechnical engineering to determine the density of a compacted material. Also known as a soil density gauge, the device uses the interaction of gamma radiation with matter to measure density, either through direct transmission or the "backscatter" method. The device determines the density of material by counting the number of photons emitted
