Tungsten alloy radiation shielding

Why we need tungsten alloy radiation shielding?

As medical science developing so repaid, 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.

Advantages of tungsten alloy radiation shielding

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. Due to a higher density, tungsten alloy has a much higher stopping power than lead. Its 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.

Tungsten alloy is a suitable raw material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high strength. It can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium in the past, tungsten alloy is more acceptable in this case, for they are non-toxic.

Appliance for tungsten alloy in radiation protection

The usage of tungsten alloy in radiation protection is not subject to NRC, EPA, or special OSHA regulations, so it has been widely used, such as:

  • Tungsten alloy radioactive source containers
  • Gamma radiography shields made by tungsten alloy
  • Shielding block of tungsten alloy
  • Source holders for oil well logging and industrial instrumentation
  • Tungsten alloy X-ray collimators
  • Tungsten alloy PET syringe shield
  • Shielding in cancer therapy machines
  • Syringe protection for radioactive injections
  • Tungsten alloy syringe shielding
  • Nuclear shielding wall
  • FDG container
  • Inspect welds
  • Nuclear testing equipment
  • Nuclear power plant shielding
  • Radiation shielding barrel
  • Isotope production, transport, and containment
  • Personal protection equipment for emergency responders
  • Large container inspection devices
  • Oncology Isotopic and accelerator based platforms
  • Pipe-line inspection Gamma
  • Defense for nuclear submarines

Tungsten alloys is a best choices for radiation shielding applications, in both medical and industrial settings. Compared to traditional radiation shielding materials, tungsten alloys radiation shield provide excellent value. A high-density 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.

Our tungsten alloys radiation shields are used for radioactive source containers, gamma radiography, shields, and industrial instrumentation. The radiation shielding is also serving as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections.

Tungsten alloy radiation shield give you best protection from the harmful radiation. Meet to the AMS 21014 and ASTM B777 material standard, we can offer tungsten alloy radiation shields with finished machining by CNC according to clients drawings.
