Tungsten-blend Fabric Shields for Radiation

As tungsten material special properties, now it is made with aramid fibre fabric as new kind of

radiation shielding material as its high-density for a better protection against X-ray and gamma-

ray radiation. Also it should be used as protective clothing.

This kinf of radiation-shielding is based on tungsten particles, high-strength para-aramid fibre.

It is said to include superior strength to polyester and other general-purpose fibres - despite

containing high concentrations of tungsten, a high-density metal that tends to impair the fibre's

mechanical properties. It also offers "excellent" flexibility as it is tungsten alloy material

based.

In addition, tungsten-blended fabric has better flame retardancy and cutting resistance than the

regular aramid fibre,  which means it is likely to be taken up in protective clothing for people

handling high-temperature objects and/or sharp-edged materials.

Tungsten Alloy Based Aramid Fiber Fabric Radiation Shielding

Here is a new aramid fiber fabric that protects users against X-ray and gamma ray radiation, which

will provide samples to selected customers for applications such as protective clothing and sheet

materials used in areas with high radiation levels.

The new fabric is produced by blending radiation-shielding tungsten particles with high strength

para-aramid fiber.

Here are some advantages:

Superior strength: the product is stronger than polyester despite containing a high concentration

of tungsten alloy, which can impair fiber’s mechanical properties.

A high level of radiation shielding from the amount of tungsten blended into the aramid fiber.

Excellent flexibility and workability properties not present in lead plates or concrete used for

tungsten alloy radiation shielding.

The tungsten-blended fabric also has a high level of flame resistance compared to regular aramid

fabric, making it useful in high-heat working conditions.

Producing a high-density metal filament yarn presents many technical difficulties. Chinatungsten

is able to leverage its fiber expertise and polymer and spinning technologies to overcome these

challenges.

Lead and lead-containing materials are typically used to shield against radiation, as lead is

comparatively inexpensive and offers excellent shielding. However, it poses significant

environmental concerns and movement is underway to regulate its use. Tungsten alloy is being

increasingly used as a more environmentally friendly alternative.

Advantage for Tungsten Alloy Collimator



 Chinatungsten Online could offer tungsten alloy collimator with the following advantages:

1. Tungsten alloy collimator is one of the most effective devices for reducing the radiation levels on a job site;
2. Tungsten alloy collimator also increases the quality of radiography shots by reducing the scattering radiation around  the film;
3. Tungsten alloy collimator can provide a safer operating conditions for radiographers;
4. Tungsten is a more effective shielding material than lead. It is an easy handle, non-licensed and very effective shielding material;
5. Tungsten alloy collimator does not spark, which makes it a ideal material for plant operations.

Tungsten Alloy Syringe Shield from Chinatungsten



Chinatungsten Tungsten alloy syringe shield reduces hand exposure and is convenient to use.
The barrel of the shield is constructed of .08" (2 mm) thick tungsten that will reduce radiation exposure from Tc-99m by more than 99% attenuation for Tc-99 tested with TLD chips. A 5.05 density (1.5 mm lead equivalency) lead glass window provides protection and visibility. A white reflective surface on the shield interior improves viewing of the syringe's markings and fluid content. A bevel around the lead glass helps protect it from scratching or breaking.
The Safe-T-Lock design provides increased protection by allowing minimal handling. The Safe-T-Lock design grips and secures the syringe upon insertion and will release the syringe at the press of a button. Disposing used syringes is easy; invert the syringe shield over a sharps container, press the release button and the syringe freely disengages.
Chinatungsten tungsten alloy syringe shields accommodate the standard sized 1 cc, 3 cc, 5 cc, 10 cc and 20 cc syringes.

Tungsten Alloy Collimator Shielding

Tungsten alloy collimator shielding is a device that narrows a beam of particles or waves. It belongs to input and output element of optical fiber communicaiton devices. It can be adopted as linear accelerator and cyclotron in medical treatment. Tungsten alloy collimator shielding has a simple structure, through which the fiber radiate light can be converted into parallel light (gaussian beam). So its main fuction is to efficiently maximize the light coupling into the device.Though a big parameter insertion loss may happen during this process, Chinatungsten has minimize the value under 0.15db. In addition to the standard parameters, Chinatungsten can manufacture tungsten alloy collimator shieldings according to the customer drawings.

Tungsten Alloy Is Suitable Material for Gamma Radiation Protection




Tungsten alloy is ideal for shielding against gamma radiation. The very high density of Chinatungsten tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics.

Why Use Tungsten as Replacement to Lead?

Why Use Tungsten as Replacement to Lead?
 Lead's popularity is mainly due to its outstanding physical properties: high density, ease of casting and fabrication, and malleability.

Tungsten is a much suitable material for lead replacement applications. It has an even higher density than lead. However, due to its extremely high melting temperature, molding tungsten into a shape is complex and costly. Still, tungsten can be formed into solids through a process called sintering. This is where tungsten and other metal powders are pressed into shape and bound in a special furnace.

Another approach to using tungsten powder as a lead replacement is currently used by many companies that manufacture non-toxic thermoplastic composite materials. These materials are mostly used for injection molding processes contain a variety of polymers and fillers.
