The density of tungsten is 60 percent higher than that of lead. That is why even thinner layers of tungsten are able to provide
reliable shielding against radiation.
Tungsten is particularly suitable as a shielding material. It consists of tungsten and a small proportion of nickel-iron. Like
tungsten, the material has excellent shielding properties.
However, it is also considerably more ductile than tungsten and can therefore be machined better.
Thanks to the ductility and high melting point of the material, isotope containers made from tungsten are also able to withstand
extreme mechanical and thermal loads.Because of their high strength, tungsten components act as both the support structure
and the shielding in one. Unlike when lead is used, no additional steel support structures are required.
