Fine Qualities of Tungsten Alloy in Nuclear Medicine

For many years, tungsten alloy has been the best choice for engineers and doctors regarding nuclear medicine. One key reason for this is the high density of tungsten alloy. In fact, it is more than 60% denser than lead, providing superior attenuation characteristics for x-ray and gamma radiation.

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.

Tungsten alloy is a best choice for the prevention of radiation in nuclear medicine. Compared to traditional radiation shielding materials, tungsten alloys radiation shield provides excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material. Using tungsten alloy reduces the finger dose received by medical staff, protecting them from exposure to harmful levels of radiation. People are taking advantage of tungsten alloy's reliable radiation shielding properties in nuclear medicine to provide a better protection for both patients and doctors.
