title: Radioactivity in two tide-washed marsh areas in the eastern Irish Sea: a radiological assessment.
abstract: The doses received by man from exposure to artificial radionuclides deposited onto marsh land during tidal inundation on the English side of the Solway Firth and the Dee Estuary have been assessed. The range of total doses received by the different marsh user groups was similar in both study areas, varying from < 1 microSv year-1 to approximately 55 microSv year-1, with total dose dominated by the contribution from external exposure (generally 80% of the total). The maximum doses in both study areas were received by people working on the marshes and are well below the annual dose limit recommended by ICRP for members of the public (1 mSv year-1). The largest dose estimated (56 microSv year-1) is only 6% of the recommended dose limit.
