Development and Application of Fingerprints of Radioactive Cesium-Plutonium-Uranium Isotopes as Tracers in Air Pollution

Recently, air pollution occurs frequently in China mainly in the form of haze, which poses great risks to human health and obstacles to social and economic development. It is well known that the sources of China's air pollution are complicated and unique, and the source identification of air pollutants is one of key points in air pollution prevention. With the development of radioisotope tracer technology, its utilization in the source identification of air pollutants has attracted increasing attention. Recently, this technology has obtained great achievements in environmental science, especially in the source identification of environmental pollutants. A variety of radioactive isotopes have been used in the source identification of air pollutants. The article presents a brief overview on the development and application of isotopes of radioactive cesium, plutonium and uranium in the source apportionment of air pollutants, as well as the existing problems and their future prospect.
