This Safety Report provides practical information as a basis for radiation protection of the public in the event of accidental releases of radionuclides to the environment, transfer from environmental media into foodstuffs and ingestion by members of the public. It offers the scientific basis for the values of committed effective doses per unit intake of radionuclides via ingestion and their application, providing the information necessary to assess the radiological implications, in terms of doses to population groups, of the measured concentrations of radionuclides in foodstuffs independent of the source of exposure.
