Applications of Tungsten alloy radiation shielding

Tungsten alloy radiation shielding is usually used in the following applications:

Non Destrcive Testing (NDT)tungsten radiation shielding
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples, which includes some kinds of microscopy to examine external surfaces in detail. Although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating electromagnetic radiation, such as X-rays or 3D X-rays for volumetric inspection.Tungsten alloy radiation shielding could be used for radiation protection from the harm radiation.

Geologging
Geologging is an exploration technique used mainly in the oil and gas industries. It is also known as wireline logging and borehole logging. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. This data can then be analysed to determine whether deposits of gas or oil are present. Tungsten alloy is used to shield the radioactive source and to act as a collimator for the gamma beam.

Pipe-line inspection Gamma
Radiation is used to inspect welds and to detect cracks in pipelines. A gamma source is mounted on a remote-controlled wheeled trolley (sometimes called a "pig") and travels inside the length of the pipe. A tungsten collimator is used to direct the radiation onto the target, whilst the radioactive source is housed inside tungsten shielding.
