Tungsten Alloy is Suitable for Gamma Radiation Shielding

Gamma radiation and X-rays are absorbed most effectively by high-density materials. Chinatungsten high-density materials are a family of tungsten-based materials with densities 50% greater than that of lead.The high-density, good mechanical strength and excellent machinability of Chinatungsten materials make them ideal for shielding applications. A variety of sizes and shapes are available.

Property:

Tungsten content(wt%): 90-97
High density   16.0~18.5g/cm3
High strength   580~950Mpa                                    
Good corrosion-resistant
Good machining property
High thermal conductivity
Low coefficient of thermal expansion
High mass absorption coefficient



Tungsten Alloy is Superior to Traditional Shielding Material

Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you’ll also reduce administration costs by eliminating the need to obtain special licensing, it’s not required.

Clients all across the globe are taking advantage of tungsten alloy’s reliable radiation shielding properties. If you need to protect yourself, your patients or your equipment from the harmful effects of excess radiation.

Chinatungsten could offer finished machined parts as rod, bar, sheet, strip, blank and rectangular blocks.



Tungsten Alloy as Radiation Protection Materials

The radiation shielding effects of some tungsten alloy was evaluated usig 133Ba(356 keV) and 137Cs(660 keV)γ-ray sources. Tungsten carbide had about the same effect as the commonly used lead, while tungsten copper alloy gave as good a performance as tungsten. The results of transmittance measurements for these materials, as well as of their Monte-Carlo simulation, are reported.

The denser the material, the better able it is to protect from radiation. That is why tungsten alloy material absorb X-rays and gamma radiation particularly well. Lead is still the most frequently used shielding material. Because it is a very soft material, it is mostly used only in combination with support structures made of steel.




Tungsten Alloy Shielding for Plasma Accelerator

Tungsten alloy shielding for plasma accelerator is used to protect staffs from radiation. Depending on heaviest density but small capacity, tungsten alloy material is more and more popular be used for making tungsten alloy shielding to protect body from plasma accelerator radiation. Compared with lead, tungsten alloy is much smaller but with heavier density, which is very helpful for high radiation absorption. It is more than 60% denser than lead, meanwhile, it has excellent machinability, good corrosion resistance. The most important thing is that, tungsten alloy is environment-friendly.


Tungsten Alloy Radiation Focusing Ring

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy radiation shieldings provide excellent density with small capacity. At the same weights tungsten alloy radiation shielding with high density alloy can provide the same energy absorption as lead using 1/3 less material.
When the tungsten alloy radiation shielding weight is certain, more density, more denser, and the thickness would be thinner. Tungsten alloy radiation shielding material could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten alloy radiation shielding material is suitable for raidation shielding.


Tungsten X-ray Protection Apron

There are wolfram anodes making from tungsten powder in the X-ray machine but the patients also have to wear a tungsten X-ray protection apron made from tungsten powder when they are making panorama X-ray of teeth or other parts on the body, due to the environmental reasons this apron is made of tungsten powder dispersed. Tungsten anodes made from tungsten powder are used in the X-ray machine; modern aprons are filled with tungsten powder, calcium tungsten powder is still used as fluorescent material in X-ray films. Tungsten powder product becomes more and more popular because of its good properties.


What Are the Different Types of Tungsten Alloy Radiation Shielding?

Tungsten alloy radiation shielding is the use of tungsten alloy to protect against ionizing radiation. Radiation occurs when energy is emitted from one substance and travels out in straight waves, possibly penetrating another substance. When this energy is absorbed, it can have the effect of exciting or destabilizing atoms. If a certain radiation penetrates an animal, it can have harmful impacts on the body, sometimes causing cancer or deformities. Shielding uses specific types of material, such as a leaded glass pane, a lead apron, or packed dirt, to act as a barrier between the body and the source of radiation.
