Tungsten
Excellent metal for radiation protection
With a melting point higher than 3,410°C, tungsten has the best temperature behaviour of all common metals.
It is also noncombustible and offers very high mechanical characteristics.
WHY CHOOSE Tungsten
- Performance: very high gamma attenuation and high technical characteristics
- Resistance: very high temperature resistance
- Modularity: machinable
- Compactness: very small footprint
DESCRIPTION
With a melting point higher than 3,410°C, tungsten has the best temperature behaviour of all common metals. It is also noncombustible and offers very high mechanical characteristics.
The most common grades are alloys at >90%W + Ni/Fe or Ni/Cu.
Thanks to their extremely high densities, tungsten and its alloys are suitable for X-ray and gamma ray shielding screens. They are used in particular in the manufacture of collimator or container components.
Tungsten: radiation protection properties
It has excellent resistance to gamma radiation. However,under neutron flux, it produces capture gamma rays, with energies between 1 and 7 MeV and is strongly activated.
