Tungsten Alloy Radiation Shield

Descripción del producto

     Tungsten Alloy Radiation Shield is a best choice for radiation shielding applications, which could be used in both medical fields and industrial areas. Compared to traditional radiation shielding materials, such as lead, it provides excellent properties. Highdensity alloy can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy's reliable radiation shielding properties.

Tungsten Medical Radiation Shielding

    Guangxi Chentian Tungsten Alloy Co., Led could offer tungsten alloy radiation shield, which is used for radioactive source containers, gamma radiography, Xray shields and industrial instrumentation. Tungsten shielding is also serving as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections. We usually offer tungsten alloy radiation shielding as per the following standard. Besides, we could also design and make special size based on different properties:

HA**0 is the most ductile and readily machinable grade. Common application areas include counterbalancing weights for the aviation and aerospace industries, crankshaft and auto racing car, bucking bars for rivet setting, and radiation shielding.

HA**5 is commonly used to produce chatterresistant boring bars and tool shanks as well as radiation shielding components.

HA**0 is often applied where size is a factor in the placement of balance or ballast weights. It should be typically of parts with small volume but heavy density. Other applications include radiation shields and collimators of xray or gamma ray beams.

HA**5：The densest of the NiFe binder alloys with tungsten, and is the preferred grade for radiation shielding in the medical imaging industry.

HA**0C: Adding copper as a substitute for iron in the binder phase, as there is requirement for nonmagnetic working environment and ideal choice for nonmagnetic radiation shielding.

HA**0C: Much denser than HA**0C, can be used in large scale shielding in nonmagnetic working environment.

Tungsten Industrial Radiation Shielding

Tungsten shielding is used in research activities as collimators (devices which guide or focus beams of radiation) or containers for radioactive isotopes. Nuclear research use nuclear reactors or cyclotrons to study or create radioactive materials. Tungsten alloy radiation shielding is ideal for radiation protection for both Xray and Gammaray. High density of it is more than *0% denser than lead, which allows a reduction in the physical size of shielding components without compromising its shielding ability.

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

Non Destructive 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 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 Xrays or 3D Xrays for volumetric inspection. Tungsten alloy radiation shielding could be used for radiation protection from the harm radiation.

When designing tungsten radiation shielding, it will be calculated according to thickness of shielding material to get total weakened multiple for layers of shield.

Formula: K = e0.**3 d / â–³1/2

K: Shield weakened multiple

â–³ 1/2: The tungsten nuclear radiation shielding material of the halfvalue layer values

d: Shielding thickness, with the halfvalue layer thickness of their units, you need to halfvalue 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.
