High-Density Tungsten Alloy Shielding Components from China Factory - Leading Suppliers for Radiation Protection
Tungsten alloy radiation shielding is usually used in the following applications
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 metallographic, 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.
Geological well drilling is an exploration technique used mainly in the oil and gas industries. It is also known as cable 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 analyzed to determine whether deposits of gas or oil are present. Tungsten alloy is used as shield the radioactive source and to act as a collimator for the gamma beam.
Radiation is used to inspect welds and detect cracks in pipelines. A gamma source is mounted on a remote-controlled wheeled trolley (sometimes called a "germanium") 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.
Why Use Tungsten Alloy Radiation Shielding?
When designing tungsten radiation shielding, it will be calculated according to thickness of shielding material to get total weakened multiple for layers of shield.
K: Shield weakened multiple
△ 1/2: The tungsten nuclear radiation shielding material of the half-value layer values
d: Shielding thickness, with the half-value layer thickness of their units, you need to half-value layer thickness of the quality of translation into the thickness of the material, divided by the density of the material can be obtained. In this way, tungsten alloy radiation shielding could be much thinner to have the same protection ability compared with other material such as lead or Al2O3.
