On March 16, 2019, researcher Liu Fudong, director of the institute of nuclear and radiation safety of the ministry of environmental protection and doctoral supervisor, delivered an academic lecture titled international NORM research progress and current management situation in China in room 21B103. The lecture is a postgraduate course of the College of Nuclear Science and Technology.

Liu first introduced the definition, range and radiation characteristics of natural radioactive materials (NORM). He explained and distinguished some commonly confused terms in radiation protection.

The report introduces the hierarchical management of NORM by the international atomic energy agency (IAEA), Canada and the European Union, and reflects the international research status and latest progress in this field.

In light of his own experience in IAEA NORM work, in which he expressed his opinions, fully demonstrated and gained recognition, Liu Fudong talked about his own experience.
