Nuclear Medicine
With the rapid development of medical science, more and more radiation instruments are used in our lives. Medical instruments x-ray and nuclear power stations have become widespread and are now affecting all our lives. It is essential that people paid more attention to radiation and even more important for the institutions to protect public from the radiation exposure and to make sure to protect every radiation source of X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc.
In order to protect patients, doctors, nurses and other people who may be exposed to radiation, sources of the radiation must be safely separated and shielded. It is crucial that holding and delivering instruments for radioactive materials would keep the radiation levels low enough, not to create harmful effects of ionizing radiation such as breast cancer, skin cancer, etc.
Advantage of Tungsten Alloy Radiation Shielding
Due to a higher density than most other materials, tungsten radiation shielding has a much higher ability to absorb and stopping almost all rays than other metals such as the traditional radiation shielding – lead. Tungsten radiation shielding greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively, equal amounts of tungsten shielding provide diminished exposure risks than equivalent lead.
Tungsten heavy alloy is the right 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 and steel), simplified life cycle and high strength. Tungsten nuclear shielding 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 (DU), tungsten radiation shielding is more friendship for the environments both lead and DU for it is not toxic.
