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
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.
