Effective shielding such as tungsten
shielding of gamma radiation is in most cases based on use of materials with two
following material properties: high-density and high atomic number.
However, low-density material such as lead can
be compensated with increased thickness, which is as significant as density and
atomic number in shielding applications. Yes, lead is also widely used as a
gamma shield, however, if the density is much lower than the tungsten shielding
material. Besides, depleted uranium could also be used for gamma radiation
shield, but it is not environmental friendly. Considering with those factors,
tungsten shielding is suitable for gamma radiation shielding. Especially for
the gamma radiation, which is much more complex than the alpha and beta radiation
shielding, in order to find a way to shield it, high density must be the most
important thing, while tungsten have the high density almost to 18.6g/cm3,
which is similar to gold. Therefore, tungsten shielding for gamma radiation is
more and more popular.
