High-Density Tungsten Alloy Shielding Components from China Suppliers and Factory for Radiation Protection
Non Destructive Testing (NDT)
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 Logging
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.
Pipe-line Inspection
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.
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.
Why is tungsten alloy chosen over traditional lead for radiation shielding?
Due to its high density, tungsten alloy provides equivalent or superior radiation attenuation while being significantly thinner and more compact compared to lead or Al2O3.
How does tungsten alloy function in Non-Destructive Testing (NDT)?
In NDT, penetrating radiation like X-rays and 3D X-rays is utilized to inspect the internal structure of samples. Tungsten alloy shielding serves to safeguard operators and equipment from harmful stray radiation.
What is the role of tungsten alloy in geological borehole logging?
During oil and gas well exploration, tungsten alloy is deployed inside boreholes to shield the radioactive gamma ray source and function as a collimator to direct the gamma beam into rock strata.
How is tungsten shielding utilized during pipeline weld inspections?
In pipeline inspection, a gamma radiation source travels inside the pipe housed within tungsten shielding, while a tungsten collimator accurately beams radiation to detect cracks and examine welds.
How is the required thickness of tungsten radiation shielding calculated?
Thickness is determined using the attenuation formula K = e^(0.693 * d / △1/2), where K represents the shield weakening multiple, △1/2 is the material's half-value layer value, and d is the shielding thickness.
