Nuclear research establishments use nuclear reactors or cyclotrons to study or create radioactive materials. Tungsten alloy shielding in industry is used in research activities as collimators (devices which guide or focus beams of radiation) or containers for radioactive isotopes. Tungsten alloy is ideal for shielding against both X- and Gamma radiation. The very high density of tungsten alloy shielding in industry (more than 60% denser than lead) allows a reduction in the physical size of tungsten alloy shielding components, without compromising the effectiveness of the shielding characteristics.
During design of shielding,tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
Formula: K=e0.693 d / △1/2
K: Shield weakened multiple
△ 1/2: The tungsten alloy radiation shielding material of the half-value layer values
d: Tungsten alloy radiation 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.
