The contributions of 137Cs-enriched particles to 137Cs concentrations in sediment samples ranged from 9% to 64%. These experiments revealed that the variability of 137Cs concentrations was due mainly to the heterogeneous distribution of 137Cs enriched particles in the samples. Therefore, the heterogeneous distribution of 137Cs enriched particles is probably one of the main factors responsible for the temporal and spatial variations of 137Cs concentrations in sediment samples.}, title = {Contribution of 137Cs-enriched particles to radiocesium concentrations in seafloor sediment: reconnaissance experiment}, volume = {13}, year = {2018} }
