Sammanfattning

The results of the project SSM2019-5225, “Marine 14C levels around the Swedish coast”, financed by the Swedish Radiation Safety Authority (SSM), are presented in the paper “Spatial and temporal variations of 14C in Fucus spp. in Swedish coastal waters” published in the Journal of Environmental Radioactivity. The project SSM2019-5225 focussed on spatial variations in 14C in Fucus spp. samples collected in 2020 along the entire Swedish west coast, in coastal waters in the very south of Sweden, and for the east coast up into the Gulf of Bothnia. In this report we present results from additional measurements of the Fucus spp. samples, using gamma-ray spectrometry (of 7Be, 40K, 60Co, 137Cs and 131I) and inductively coupled plasma mass spectrometry (ICP-MS) (of Co, Ni, Cd, Gd, Hg and Pb). The gamma spectrometry showed in addition to the expected content of natural 40K also 137Cs and 7Be, and at some places also 60Co and 131I. The ICP-MS analysis revealed a correlation between F14C and Gd, and the highest values of F14C and Gd were found close to Ringhals nuclear power plant. This strengthens the hypothesis that that a significant part of the observed peak in F14C on the west coast originates from Ringhals nuclear power plant.
