Radiocaesium from Chernobyl in benthic algae along the Swedish Baltic Sea coast

摘要

The concentrations of (sup 137)Cs, (sup 134)Cs and (sup 40)K were measured in algal samples taken from the upper littoral along the Swedish Baltic Sea coast in 1990 and 1991. The results were compared with earlier measurements carried out 1984-1989, and some unpublished data from these years are presented as well. The levels of radiocesium in algae that belong to different algal groups were compared, and the value of different algal species as monitoring organisms for radionuclides in the Baltic Sea was discussed. Suggestions for future monitoring and future research are given. 10 refs, 5 figs, 10 tabs. (Atomindex citation 26:005335)
