Tungsten Alloy Radiation Container

Tungsten Alloy Radiation Container
Tungsten alloy is used in many radiation-shielding applications including industrial, nuclear and
medical. Because of its high density and high atomic number, is an effective construction material
for shielding against gamma rays and x-rays. Lead and boron carbide can shield radiation too, but
cannot perform as well as tungsten alloy.
Tungsten alloy is a suitable raw material for tungsten alloy radiation container, because of
tungsten alloy radiation container combination of radiographic density (more than 60% denser than
lead), good machinability, good corrosion resistance, high radiation absorption (superior to lead),
simplified life cycle and high strength. Tungsten alloy radiation shielding can provide the same
degree of protection as lead whilst significantly reducing the overall volume and thickness of
shields and containers. Moreover, compared with lead or depleted uranium, tungsten alloy is more
acceptable in this case, for it is non-toxic and environmentally friendly material.
Why Use Tungsten Alloy Radiation Shielding?
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten
alloy radiation shielding provide excellent density with small capacity. At the same weights high
density alloy can provide the same energy absorption as lead using 1/3 less material. When the
weight is certain, more density, and the thickness would be thinner. Tungsten alloy radiation
container material could be made with thinner thickness but high absorption of radiation in high
density. That is why tungsten alloy material is suitable for tungsten alloy radiation shielding.


Formula: K = e0.693 d / △1/2
K: Shield weakened multiple
△ 1/2: The shielding material of the half-value layer values
d: Shielding thickness, with the half-value layer thickness of their units, you need to half-value
layer thickness of the quality of translation into the thickness of the material, divided by the
density of the material can be obtained.


A main application of tungsten alloy products, tungsten alloy radiation containers are widely
applied in medical and nuclear industries.

Owing to its excellent radiation resistance, tungsten heavy alloy has gradually replaced lead
shields to become the main shielding materials in many industries to protect the radiation.
Tungsten alloy radiation container is a flexible heat-resistant tungsten alloy raidation shielding
made of tungsten and iron metal powder immersed in a silicone polymer. Lead blankets have been the
backbone of tungsten alloy radiation shielding applications for years but, in comparison, is a
less effective and efficient tungsten alloy raidation shielding choice. Due to the ability to place
the maximum amount of weight between the source and the worker, the new generation tungsten alloy
radiation shielding has proven to be up to twice as effective as lead in lowering exposure rates.
Designed in custom shapes, tungsten alloy radiation container has the ability to field-fit,
providing for attenuation of radiation totaling from 5 to 10 person-Ram/years than provided by the
equivalent weight of traditional lead blanket. Additionally, the tungsten alloy radiation shielding
weighs 25 to 50 percent less than lead while removing the accompanying toxicity hazard and mixed
waste processing costs.
