Applications of tungsten alloy Industrial radiography

Tungsten alloy is used as Industrial radiography shielding in the following applications:

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.

The penetrating power of radiation has also been put to use in the fight against terrorism. The Homeland Security industry has designed scanners that use gamma radiation to detect objects in cargo containers or airline baggage.

The radioactive sources are very strong and require WOLFMET tungsten shielding to protect security staff and members of the public from the radiation. A tungsten collimator is also required to direct the gamma radiation onto its target.
