Tungsten Shielding for Gamma Radiation

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.

Tungsten Radiation Shielding for Medical Industry

X-Ray existed in medial industry has very high intensity radiation primarily for component inspection of critical manufactured parts. The inspection of welds for example is of prime importance in any aircraft component or in the inspection of nuclear power plant piping. That type of X-Ray for the inspection is the expensive micro processing circuitry. Radiation shielding for medial industry applications require thicker lead or thicker lead-equivalent glass in lead lined wall material or shielded doors. Doors may also require borated polyethylene to shield from neutron scattering. The highest level of shielding is required badly for X-ray in medical industry. As far as I know, tungsten alloy with density from 17.0g/cm3 to 18.5g/cm3 has excellent radiation absorption for X-ray. Besides, due to its good machinability, it could be machined into different shapes, such as brick, working as the tungsten radiation shielding wall, each brick is manufactured with four tongue and groove edges for interlocking. In this way, X-ray in medical industry could be absorbed well by tungsten radiation shielding.
