Tungsten--Lead Replacement Material for Radiation Shielding

It is widely known that frequent contact and exposure to radiation are hazardous to human health and detrimental to the equipment. Therefore, many radiation shielding applications have been installed to protect people and the working facilities from the harmful rays as well as to comply with work-safety regulatory requirements.For a long time, lead has been the leading material used in radiation shielding structures and applications. However, lead has come under severe criticism in recent years due to its disastrous impacts on people and the environment. Research shows that lead can negatively impact human’s nervous and reproductive system, weakening the muscles and damaging the brain. Therefore, the need for lead replacement and lead substitute materials is highlighted when selecting radiation shielding materials.

Tungsten as the new material is being developed to serve as lead replacement material that is100% lead equivalent in radiation shielding efficacy. Tungsten, which is a hard and rare metal and often exists in the form of chemical compound, serves as an efficient lead replacement material. Tungsten alloys have high density and hardness, in fact almost 60 percent higher than lead, which are desirable characteristics for radiation shielding applications. They can be used to mitigate X-ray and gamma rays. Other benefits of tungsten-based materials include their high temperature resistance and environmental friendly.
