China has achieved the mass production of carbon-14 isotopes via its commercial reactor for the first time, announced the China National Nuclear Corporation (CNNC). According to the CNNC, the project was carried out in China's very first nuclear power plant, Qinshan, and the production capacity is expected to fully meet domestic demand, as some 150 curies of carbon-14 were produced, much higher than the annual import of around 100 curies. Carbon-14 is widely applied as a marker in agriculture, chemistry, medicine, biology and other fields for being radioactive and detectable.
