Applications of tungsten alloy collimator shielding

Tungsten alloy is used as collimator shielding in the following applications:

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 inspectionGamma
　
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 WOLFMET tungsten collimator is used to direct the radiation onto the target, whilst the radioactive source is housed inside tungsten shielding.

Homeland Security and Border Control
　
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.
