Radiocesium in marine fish, shrimps and scallops in coastal waters in Northern Norway and in the Barents Sea, measured over a period of two years

The paper deals with a national programme for assessing the radioactivity in marine species important for human consumption. The programme that started in 1993 and will continue for several years, focuses on the marine area of Norway north of the Arctic Circle. Using NaI detectors, measurements of 59 samples from fish, shrimps and scallops have recently been made. In all samples the radioactivity was below the detection limit (29 Bq/kg wet weight). Compared to the intervention levels for foodstuff, this level is negligible. 4 refs., 2 figs., 1 tab
