Studies now show that tungsten, which is also used in welding, metal cutting, and other applications, is not as chemically inert as previously thought. Some forms of tungsten can move readily though soil and groundwater under certain environmental conditions. Both the U.S. Department of defense and the environmental protection agency now classify the element as an "emerging contaminant" of concern. Tungsten alloy material is widly used as substitution for lead, and is considered as tungsten alloy health material working as fishing weight and military fitting parts compared with DU.
Scientists think that tungsten is much less toxic than lead or mercury. Tungsten has been shown to act by antagonizing the action of the essential trace element, molybdenum. Long industrial experience has indicated no pneumoconiosis to develop among workers exposed solely to W or its insoluble compounds.
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 delivery 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. Lead and steel are the traditional protection materials, but tungsten alloy radiation shielding is without a doubt the best solution. Excellent radiation-absorption, twice the density of lead and good physical resistance are main reasons to use tungsten alloy radiation shielding. Tungsten alloy health is a hot tipic for environment protection and human protection from radiation.
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloys provide excellent density with small capacity. With the same weight, high-density alloy can provide the same energy absorption as lead using 1/3 less space.
Tungsten heavy alloy is best choices for tungsten alloy health applications, in both medical and industrial settings.Tungsten alloys radiation shield provide excellent alternative for traditional radiation shielding materials. High-density tungsten heavy alloy radiation shielding can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy's reliable radiation shielding properties.
