Tungsten alloy is more and more widely used for radiation protection to shield people or objects from radiation. For example, it is promising in applications of converging collimator – an important part of human brain SPECT, which is known to increase the photon detection efficiency compared to conventional parallel-hole collimator in SPECT imaging. That is because tungsten alloy is poison-free with better radiation shielding ability than lead (poisonous).
