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.
