Contribution of (137)Cs-enriched particles to radiocesium concentrations in seafloor sediment: Reconnaissance experiment

Autoradiography was used to detect (137)Cs-enriched particles in sediment samples. The contributions of (137)Cs-enriched particles to (137)Cs concentrations in sediment samples ranged from 9% to 64%. These experiments revealed that the variability of (137)Cs concentrations was due mainly to the hete...

Sumario:Autoradiography was used to detect (137)Cs-enriched particles in sediment samples. The contributions of (137)Cs-enriched particles to (137)Cs concentrations in sediment samples ranged from 9% to 64%. These experiments revealed that the variability of (137)Cs concentrations was due mainly to the heterogeneous distribution of (137)Cs-enriched particles in the samples. Therefore, the heterogeneous distribution of (137)Cs-enriched particles is probably one of the main factors responsible for the temporal and spatial variations of (137)Cs concentrations in sediment samples.
