Radioactive waste from Sellafield has been found in Scottish farmed salmon sold in major British supermarkets. Tests commissioned by Greenpeace revealed traces of radioactive waste in packets of fresh and smoked salmon.
Tc-99 is a byproduct of Magnox fuel reprocessing. Dr David Santillo, a scientist at Greenpeace's research laboratories at Exeter University, said: "Tc-99 should not be there at all. It is inexplicable yet significant. Scottish salmon is marketed as something that comes from a pristine environment."
