This project describes the application of bioindicator systems
intended for the measurement of the low level radioactive contamination
around nuclear installations. The system has been
applied around the Swedish and Finnish nuclear power plants
and has, furthermore, been used in a study of the dispersion
of the effluents from the British nuclear reprocessing plant,
Sellafield. The doses to man from these installations have
been calculated and compared with the natural background radiation
received from the consumption of marine fish.
