The Greenpeace research found traces of the radioactive waste in salmon on sale in major supermarkets and has blamed this on emissions from the Sellafield nuclear reprocessing plant in Cumbria.
Westminister Environment Minister Elliot Morley announced that his department would write to nuclear operator BNFL for a nine-month moratorium on emissions of low level Technetium-99 .

The tests were conducted by the Greenpeace research laboratory at Exeter University.
