Tungsten alloy has is ideal for medical radiation shielding against X-rays and gamma radiation because of the good advantages of it such as: high radiation resistance, high density (more than 60% denser than lead) with small volume, high temperature resistance, non-toxic and environmentally friendly. Radiation shielding used in medical areas in former days was usually made by lead, but lead is toxic so tungsten alloy is the first choice to substitute lead in medical radiation shielding. Tungsten alloy medical radiation shielding used in applications of collimator, nuclear shielding, beam stopper, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.
