Temporal variation of cesium isotope concentrations and atom ratios in zooplankton in the Pacific off the east coast of Japan
After the Fukushima Daiichi Nuclear Power Plant accident in March 2011, concentrations of cesium isotopes ( 133 Cs, 134 Cs, and 137 Cs) were measured in zooplankton collected in the Pacific off the east coast of Japan from May 2012 to February 2015. The time series of the data exhibited sporadic 137...

| description | After the Fukushima Daiichi Nuclear Power Plant accident in March 2011, concentrations of cesium isotopes (
133
Cs,
134
Cs, and
137
Cs) were measured in zooplankton collected in the Pacific off the east coast of Japan from May 2012 to February 2015. The time series of the data exhibited sporadic
137
Cs concentration peaks in zooplankton. In addition, the atom ratio of
137
Cs/
133
Cs in zooplankton was consistently high compared to that in ambient seawater throughout the sampling period. These phenomena cannot be explained fully by the bioaccumulation of
137
Cs in zooplankton via ambient seawater intake, the inclusion of resuspended sediment in the plankton sample, or the taxonomic composition of the plankton. Autoradiography revealed highly radioactive particles within zooplankton samples, which could be the main factor underlying the sporadic appearance of high
137
Cs concentrations in zooplankton as well as the higher ratio of
137
Cs/
133
Cs in zooplankton than in seawater. |
