Industrial radiography is a way to perform non-destructive testing. It uses ionizing radiation to inspect materials and components, locating and quantifying defects or degradation in material that would lead to failure. Industrial gamma radiography uses gamma rays generated by the natural radioactivity of sealed radionuclide sources. It is also possible to perform tomography in nearly real time.

While industrial radiography is usually associated with medical applications, it is applicable to components across an extensive range of sectors. Our radiography components are used to perform a variety of jobs, such as:

• Inspecting welds and castings
• Food inspection
• Airport security checkpoints
• Evaluating nuclear test equipment
• Neclear shields
• X-ray Collimators
• Other types of radiation detectors

Properties

Its Mechanical properties are of tensile strength, ductility and hardness plus other elemental metals, create a family of tungsten alloy materials that have found wide acceptance where a concentrated mass is required in a limited space. Tungsten alloys guarantee the strength and stability needed for the tough oil and gas drilling process.  Tungsten alloys are economically fabricated by powder metallurgy techniques and routinely machined by conventional methods. So it can be delivered both as a semi finished product for further processing by the customer or in accordance with the customer's drawing as a finished machined part.

 
Characteristics and features

As medical science developing, there is more and more radiation in our life, which has become a new trouble, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc.  In order to protect patients and other people safe from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc. One type of excellent radiation-absorbing medium is badly needed.

Experts find that radiation exposure could be reduced by maxing shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding. With a higher density, tungsten alloy has a greater protection than lead. It is greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten alloy shielding provide diminished exposure risks than equivalent lead shielding.

1. Can be machined to different shapes per customer drawings and requirements. 
2. Good corrosion resistance
3. High radiation absorption (superior to lead)
4. Simplified life cycle and high strength.
5.  Non-toxic material as a replacement to lead

Application

Tungsten alloy radiation shields are made to only allow radiation to go where it is actually needed. Our tungsten radiation shields guarantee that environmental radiation exposure is kept to an absolute minimum during the generation of X-ray radiation.  A particularly dense material with excellent shielding properties is needed to ensure that the surrounding tissue is protected and the radiation guided only to the intended locations where those are widely used in Medical and Industrial Radiation Shielding.

There is no licensing required for tungsten alloy materials. Tungsten alloys are stable at high temperatures. You can use one-third less material than lead for the same energy-absorbing effectiveness and also it is non-toxic.  You can use our high density tungsten alloys for shielding wherever radioactivity has to be controlled and directed.   Xi'an Kefeng Powder Metallurgy Co., Ltd. specializes in producing tungsten radiation shields according to customer's drawing.
