Review on the Application and Production of 14C in China

Carbon-14 is widely used in labeling and tracing，clinical disease diagnosis，research and development of new drugs，and environmental monitoring. In the 20th century，China carried out research on the production of carbon-14 nuclides and develpoed various preparation process for carbon-14 nuclides，but failed to realize large-scale production. In recent years，the supply of carbon-14 nuclides has become tight，which limits the development of related application industries. This paper briefly describes the domestic application of carbon-14，the production process methods of carbon-14 nuclides by nuclear reaction，as well as the current status of domestic carbon-14 production research and the construction of bases with carbon-14 production capacity. It is expected that a comprehensive independent supply of carbon-14 nuclides can be realized in the near future，which will help the high-quality development of nuclear technology application industry.
