Tungsten Alloy Shielding Used For Agriculture

With the development of radiation technology, it is widely used in various fields. In the medical field, it is used to diagnose the abnormal changes in tissues and organs of the body and cancer therapy; in industry, it is used in the automated quality control of industrial production line and the detection of the casting crack and weld crack; in the food safety, it is used for food preservation, food sterilization; in agriculture, it is mainly used for radiation breeding, isotopic tracing and radiation disinfestation. Among them, radiation breeding is the use of ionizing radiation to treated with crops to induce mutations, then choosing good variation individuals to cultivate to obtain new varieties; isotopic tracing is the technology that introduce the radioisotope into the body of plants and animals, and then research the growth rhythm or the absorption condition of nutrition of plants and animals by using the radiation detector to track the absorption, accumulation and transfer conditions of isotopes in the body; while the radiation disinfestation is a method that uses radiation source to irradiate injurious insect, resulting in dominant lethal mutations in the body of insects and causing the abnormal mitotic, then overwhelming numbers of sterile insects are released into the wild.

Tungsten alloy shielding is widely used in the agriculture field due to its excellent radiation shielding performance. Radiation can cause harm to human body by accelerating the decline of the cells, causing cell abnormalities or inhibiting the generation of new cells, or causing changes in the body's biochemical reactions. Long-term exposure to radiation can also lead to serious damage to human organs and systems, as well as causing leukemia, cancer, reproductive system diseases, aplastic anemia and other diseases. Thus, people should pay attention to use the tungsten shielding for the application of radiation technology in agriculture to shield and absorb radiation. Scientists have discovered that the radiation shielding property of a metal material increases with its density, the higher density means the better radiation absorption capacity and radiation shielding ability. Compared to other traditional materials (such as lead), tungsten alloy has higher density, therefore tungsten alloy shielding has better radiation shielding performance. And tungsten alloy shielding is non-toxic and is extremely environmentally friendly shielding material.
