Tungsten alloy industrial radiography uses gamma radiation to detect structural faults in materials such as metal and concrete. As with pipe-line inspection, the equipment uses tungsten shielding, coupled with a tungsten collimator.
Thickness, density and level gauging Radioactive sources are used in industrial processes to measure thickness, density or levels of materials during production e.g. paper, plastic film, steel sheet or surface coatings. The material passes between a radioactive source, which is housed in tungsten alloy, and a detector. The strength of the detector signal is used to measure the thickness, density or level of the material.
