[en] Radiological safety during the transport of radioactive materials is closely related to the capabilities of packings and to their capacity to limit the hazards of direct irradiation and contamination of the environment. For some typical types of transport (irradiated fuels, high-level wastes, uranium hexafluoride, air transport) the author uses hypotheses concerning the development of the production of nuclear energy in France in 1980 in an attempt to evaluate the collective doses under normal conditions and the consequences of certain accident sequences for individuals of the public
