Radioactive material is used throughout the world for many applications that benefit humankind encompassing agriculture, industry, medicine, electric power generation and research. The transport of this material places it outside of controlled facilities, in the public domain, and often entails movement between countries. The IAEA was assigned the task of developing, maintaining and providing the application of safety standards for the transport of radioactive material. This conference was convened to discuss the safety of the international transport of radioactive material. It was co-sponsored by the ICAO, IMO and UPU. These proceedings contain the opening addresses, papers from the background session and other papers presented at the conference, summaries of all discussions, and the summary and findings of the conference president. Contributed papers are provided in a CD-ROM that accompanies this volume.
