Tungsten Alloy in Waste Handling

Nuclear waste is unstable containing elements α, β and γ radiation and is accompanied by heat generation of unwanted material. Nuclear waste into the environment can cause water, air and soil pollution, and enter the body through various means, when radioactive radiation exceeds a certain level, you can kill the organism's cells and interfere with normal cell division and regeneration, causing the genetic cell mutation information. Is the use of deep geological methods. Common type repository mine, located 300 to 1500 meters deep. Structure of the library include natural barriers and engineered barriers to prevent the waste from leaking radionuclides in the package, but it is difficult to ensure that up to hundreds of years in the packaging material from corrosion, formation does not change.

For protecting personnel from contact with radioactive waste materials tungsten can be used to produce sample pots and transport containers in a variety of shapes and sizes. Tungsten provides a superior level of attenuation in comparison to alternative materials such as lead, especially for gamma radiation. This can reduce the wall thickness and weight of the sample vessels, making them easier to handle. Tungsten alloy can also be used to produce shielding components for waste or fuel handling systems, such as gamma gates.
