Nuclear research establishments use nuclear reactors or cyclotrons to study or create radioactive materials. Tungsten alloy is used in research activities as collimators (devices which guide or focus beams of radiation) or containers for radioactive isotopes. tungsten alloy is ideal for shielding against both X- and Gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising the effectiveness of the shielding characteristics.

 

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