Nuclear Technology And Tungsten Alloy Shielding

Nuclear technology refers to the modern new and high technology and one of the signs of social modernization which is based on the nuclear reaction, nuclear properties, nuclear effect and nuclear spectroscopy, and with radiation source, nuclear radiation detector, accelerator and reactor as its tools. Nuclear technology is an important method for early diagnosis of certain cancers, coronary heart disease and brain dysfunction. Its sensitivity, selectivity, specificity, interference, penetrating are so high that it is widely used in various fields of national economy as well as medical care, food preservation, agriculture, industry and hydrology aspects. Nuclear technology can be divided into military nuclear technology, nuclear power and civilian nuclear technology, of which civil nuclear technology is the most active, including radiopharmaceuticals, radiation processing technology, nuclear diagnostic technology, nuclear instrumentation, nuclear analytical techniques.

Nuclear technology not only has brought a variety of convenient, but also brought the nuclear radiation. For the question about the long-term effects of nuclear radiation on people, the study of Atomic Energy Commission geneticist James • Nair and his colleagues shows that the probability to have cancer for the people surviving from nuclear radiation is higher than ordinary people. In fact, many survivors suffered from thyroid cancer, lung cancer, breast cancer, leukemia and other cancers, and some people suffered from mental abnormalities after Hiroshima and Nagasaki nuclear explosions suffered. Many examples show that pregnant women subjected to nuclear radiation can lead to fetal malformation, fetal death and other diseases.

Tungsten alloy shielding can effectively shield the nuclear radiation generated in the use of nuclear technology to avoid it causing harm to humans. Since tungsten alloy combines high density, good machinability, good corrosion resistance, high radiation absorption capacity and high intensity, it is the best raw materials for radiation shielding. In the situation of reducing the volume and thickness of shielding, the radiation shielding performance of tungsten alloy shielding is still equivalent to that of lead. In addition, compared to lead and depleted uranium, tungsten alloy is more environmentally friendly.
