Tungsten Alloy And Nuclear Radiation Protection

With the development of China's modernization, the application of radioactive substances and nuclear radiation technology has been developing rapidly. Nuclear radiation, or commonly referred to radioactivity, is the micro-particles released by nucleus from the conversion process of an energy state or a structure into another structure or another energy state. Currently nuclear radiation sources have been widely used in industrial, medical, scientific research, agriculture and other fields, such as for the flaw inspection of petroleum pipeline transportation and large machines and food sterilization and preservation. Although the application and research of nuclear energy has brought country and people huge benefits, but its harm also should not be underestimated.

Nuclear radiation has harmful effects on the human body, once the body is irradiated with the nuclear radiation, it can cause nausea, vomiting, spontaneous bleeding, dizziness, insomnia, skin redness, ulcers, bloody diarrhea, skin peeling, hair loss, severe fatigue, gastrointestinal disorders and other symptoms, in severe cases it can even cause nerve cells, gastrointestinal cells and immune system damage. Due to the nuclear radiation will block the metabolism of cells, a large number of cells will grow, which can also lead to lung cancer, leukemia, thyroid cancer, breast cancer and other cancers. Sometimes nuclear radiation will increase distortion, the incidence of hereditary disease, affecting the health of generations. In general, the more radiation energy received by the body, the greater the risk of cancer, birth defects will be.

Tungsten alloy can be used for nuclear radiation protection due to its high radiation shielding performance. Compared with the traditional shielding materials (such as lead), tungsten alloy shielding has higher density, thus in the condition of the same weight, the volume of tungsten alloy shielding is smaller, but its radiation shielding performance is not diminished. Further, lead shielding is toxic which can harm human health and pollute the environment, while the problem does not exist in the tungsten alloy shielding.
