The isotope and radiation technology and its applications is an important milepost in twentieth Century the history of human civilization, is a high-tech recognized, its application level is an important symbol of a country's comprehensive national strength, is the focus on the development of world power field.

    At present, nearly 150 countries and regions in the world have carried out the research and development of nuclear technology. In recent years, especially after entering the last century in 90s, the United States and Japan as the representative of the developed countries in the world, with the support of the government and the market pull, has formed a high degree of correlation, energy saving, high efficiency and no pollution of the emerging industry, modeling of conventional nuclear technology industry in the world nearly trillion. Isotope and radiation technology has become a global technology, with high permeability and strong industrial relevance, and its development can lead to sustained growth and social progress of the national economy.

    The application of nuclear units in China in the field of national economy and technology has reached tens of thousands, with the application of nuclear technology in the national life of the dozens of all areas, with nearly more than 100 kinds of products, many products and technology in coal, petroleum, chemical industry, information industry, iron and steel, machinery, medical and other industries in the field of nuclear technology. The application of products has been essential. At present, China produces and supplies more than 70 isotopes of isotopes and more than 1000 products. It is one of the few countries in the world with an annual output of 5 million Curie cobalt and -60 radiation sources.

    Radioactive isotopes are to make significant contributions to improving the national health care, fluorodeoxyglucose (FDG/18FDG) for various types of cancer staging and follow-up treatment, -177 and -90 isotopes of lutetium yttrium is frequently used in the medical field. Using ray to realize mutation breeding, insect killing, sterilization and food preservation is of great economic significance to agriculture development. The radiation processing of modified polymers for industrial applications more and more widely, from wire and cable, foam, radial tires, batteries and air filters to wound dressings, wear-resistant resin, deodorant and so on a variety of products are from radiation processing technology. Environmental monitoring of ocean, land and atmosphere using isotope technique has been widely used in environmental monitoring.

    The development speed of our gamma irradiation facility and industrial accelerator is the fastest in the world. The built irradiation units of more than 300 thousand Curie 120, built in 8, the total installed capacity of 140 million design source Curie; built more than 5kW of power electron accelerator reached 171 units, 22 units under construction, the total power is more than 140 million kW. The global production and operation of large-scale radiation inspection equipment have been realized. The large-scale production and use of industrial on-line inspection devices and nuclear instruments and meters have made important contributions to the development of the national economy.

    As the International Atomic Energy Agency (IAEA) as the evaluation, "the breadth of applications, only modern electronics and information technology and the ability of isotope and radiation technology, isotope and radiation technology is making a valuable contribution to the development of the world economy."
