Tungsten alloy radiation shielding
Experts find that radiation exposure could be reduced by maxing shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding.
Due to a higher density, tungsten alloy has a much higher stopping power than lead. Its greater linear
attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal
amounts of tungsten alloy shielding provide diminished exposure risks than equivalent lead shielding.
Tungsten alloy is a suitable raw material for radiation protection, as its combination of radiographic density
(more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption
(superior to lead), simplified life cycle and high strength. It can provide the same degree of protection as
lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides,
compared with lead or depleted uranium in the past, tungsten alloy is more acceptable in this case for they are non-toxic.
