What are the main conclusions?
Many cancers (including leukaemia) were shown to cluster in a non-random fashion in high socio-economic areas. The clustering was not more marked near nuclear power generating plants but there were excesses of some types of cancer near Sellafield, Dounreay, Aldermaston, Burghfield and Harwell. There was also a trend of risk with distance from Rosyth. The excesses, types of cancer and time scales were not consistent around these sites.
