Publication Abstract

Derived concentration factors for caesium-137 in edible species of North sea fish

A.K. Steele

Concentration factor (CF = Bq/kg fillet/Bq/kg filtered sea water) values for super(137)Cs in fillets of cod (Gadus morhua), haddock (Melanogrammus aeglefinus ), plaice (Pleuronectes platessa) and whiting (Merlangius merlangus), were derived from fish and filtered seawater concentrations. Samples were collected in twelve sampling boxes in the North Sea over an eight-year period--1978-1985. The range of results with species, between species, and between surveys are discussed. Mean CF values of 92, 58, 39, and 150 were found in cod, handdock, plaice, and whiting respectively. These support the IAEA recommended CF value of 100 for fish in generalised dose assessments.
